DEPRESSION
SPECIFICTION: The behavioural, emotional and cognitive characteristics of depression. The cognitive approach to explaining and treating depression: Beck’s negative triad and Ellis’s ABC model; cognitive behaviour therapy (CBT), including challenging irrational thoughts.
THE EMOTIONAL, BEHAVIOURAL, AND COGNITIVE CHARACTERISTICS OF DEPRESSION
Clinically, depression, or major depressive disorder, is diagnosed when an individual experiences at least five significant symptoms over two weeks, one of which must be a pervasive feeling of sadness or a noticeable loss of interest and pleasure in most daily activities. These symptoms significantly impact daily functioning, encompassing emotional, behavioural, and cognitive domains.
These symptoms are not attributable to the physiological effects of a substance or another medical condition, highlighting the necessity of a thorough clinical evaluation for accurate diagnosis and treatment planning.
THE EMOTIONAL CHARACTERISTICS OF DEPRESSION
Emotional characteristics of depression are marked by a persistent feeling of sadness, emptiness, or a sense of hopelessness. Individuals may experience a profound loss of interest or pleasure in activities that were once enjoyed, leading to diminished engagement with daily life. Feelings of worthlessness or excessive guilt are common and often disproportionate to the situation. Depression can also manifest as irritability or frustration, even over small matters, which can strain relationships. In severe cases, thoughts of death or suicide may emerge as the individual struggles with the overwhelming emotional burden of depression.
THE BEHAVIOURAL CHARACTERISTICS OF DEPRESSION
Behavioural characteristics of depression encompass a range of actions and inactions that are observable in individuals suffering from this mental health condition. These characteristics typically include a significant energy loss, resulting in pervasive fatigue and lethargy, making the person highly inactive and unenthusiastic about engaging in previously enjoyable activities.
Furthermore, individuals experiencing depression often demonstrate notable social impairment, which manifests as a marked lack of social interaction with friends and family. This isolation can exacerbate feelings of loneliness and contribute to the cycle of depression.
Changes in weight, either through loss or gain, are also common behavioural indicators of depression. These changes can directly result from altered eating habits, such as under-eating due to a lack of interest in food or overeating as a form of emotional comfort.
Poor personal hygiene is another behavioural characteristic of depression. Individuals may neglect personal grooming tasks such as bathing, changing into clean clothes, and maintaining general cleanliness, indicating a diminished concern for personal well-being.
Sleep disturbances, including constant insomnia or oversleeping (hypersomnia), are also prevalent among those with depression. These sleep issues not only reflect the disorder's impact on physical health but also contribute to the overall severity of depressive symptoms by affecting energy levels, mood, and cognitive function.
THE COGNITIVE CHARACTERISTICS OF DEPRESSION
Cognitive characteristics of depression encompass various symptoms related to how individuals think and process information. A defining feature of depression is the prevalence of negative and irrational thinking patterns or cognitive distortions that individuals have about themselves and their outlook on the world. Individuals may possess a pervasive belief that situations will turn out badly, which can become a self-fulfilling prophecy due to their subsequent lack of effort or motivation. This cycle can further entrench depressive thinking patterns.
Affected individuals often experience a significant lack of concentration and focus, making engaging in tasks requiring sustained mental effort difficult. This can lead to pronounced indecisiveness, as even making minor decisions becomes an overwhelming challenge.
Suicidal thoughts are a severe and distressing cognitive symptom of depression, reflecting the depth of despair and hopelessness the individual feels. Additionally, those suffering from depression may exhibit poor memory and struggle to recall details and events, which can impair their daily functioning and social interactions.
THE COGNITIVE APPROACH TO EXPLAINING DEPRESSION
PLEASE NOTE
The specification states you need to know Ellis’s ABC model (1962) and Beck’s Negative Triad (1967). These two are specifically named in the A-level psychology specification, meaning you must know them intricately.
Fortunately, as they are both cognitive models, much of the general evaluation for one model can be used for the other.
To achieve full marks, it's essential to discuss cognitive models applied to depression only. Simply discussing the cognitive approach on its own is not enough. This specification requirement emphasizes the importance of linking theories, such as Beck's Cognitive Triad or Ellis' ABC Model, specifically to depression, demonstrating their relevance to this condition.
ELLIS’ ABC MODEL
Ellis' model highlights the crucial role of individual cognition in emotional well-being, suggesting that our internal belief systems significantly influence our reactions to life events. These beliefs, often formed through past experiences, shape our interpretation of current events, influencing our emotional state. Ellis proposed that irrational beliefs, which are unrealistic and unhelpful, can lead to negative emotional outcomes. For instance, a person who believes they must succeed at everything they attempt may experience intense distress when faced with minor setbacks. This distress isn't directly caused by the setbacks themselves but by the person's belief that they signify failure or inadequacy. This model underscores the importance of addressing these underlying beliefs through therapeutic interventions to mitigate their impact on mental health.
COGNITIVE DISTORTIONS AND IRRATIONAL BELIEFS
A cognitive distortion is essentially a pattern of thinking that deviates from rational, logical reasoning. It's a psychological mechanism through which individuals convince themselves of a reality far from accurate, often skewing towards a negative perspective. These distorted perceptions commonly fortify undesirable emotions or thoughts, convincing individuals of their validity despite being counterfactual.
For example, consider someone who believes, "I always mess up whenever I try something new; therefore, I'm a failure in everything I attempt." This thought process embodies "black or white" or polarized thinking, where the individual perceives situations in extremes. They either see total success or complete failure, with no middle ground. If they extend this thought to "I must be an utter failure," it further illustrates overgeneralization. Here, they're expanding on one specific failure to define their identity and worth.
Cognitive distortions are central to what cognitive-behavioral therapy (CBT) and similar psychotherapeutic approaches aim to address. The goal is to assist individuals in recognizing these distorted thought patterns, challenging and refuting irrational or exaggerated thoughts. By consistently countering these negative beliefs, individuals can gradually replace them with more balanced and rational thinking. This shift in mindset can significantly diminish the power of cognitive distortions over time, fostering a healthier mental state.
MUSTABATORY THINKING
Mustabatory thinking is a term introduced by Albert Ellis, a key figure in the development of Rational Emotive Behavior Therapy (REBT), to describe a form of irrational thinking where individuals believe they must have certain things or must act in a certain way to be happy, successful, or valued. This thinking pattern is characterized by rigid "musts," "oughts," and "shoulds" that people impose on themselves and others.
Mustabatory thinking often leads to emotional distress because it sets up unrealistic and inflexible demands. For example, someone might think, "Everyone must like me" or "I must perform perfectly in every task." When these stringent, self-imposed rules are not met, it can result in feelings of failure, anxiety, depression, or anger. Ellis argued that challenging and changing these irrational beliefs is crucial for overcoming emotional distress and achieving a healthier, more rational way of thinking. Facilitatory thinking is pivotal in encouraging irrational beliefs by establishing unattainable expectations for individuals. Not meeting these expectations can lead to negative thoughts and, in more severe instances, culminate in conditions such as depression.
POLARISED THINKING (BLACK-AND-WHITE THINKING)
Viewing situations, people, or self-evaluation as entirely good or bad, with no middle ground. For example, if a person makes a mistake, they may believe they are a total failure, disregarding any positive aspects of their abilities.
OVERGENERALISATION
Drawing broad conclusions based on a single event or limited evidence. For example, after a minor setback, someone might think, "I always fail," applying this negative outlook to all future events.
CATASTROPHISING
Imagining the worst possible outcome in any situation. For example, a minor health issue may be interpreted as a catastrophic illness, creating disproportionate anxiety.
PERSONALISATION
Assuming responsibility or blame for external events without evidence. For instance, if a friend is upset, a person might believe they are the cause, leading to feelings of guilt or worthlessness.
MIND READING
Assuming what others are thinking without any factual basis. For example, believing that everyone views you negatively without any real feedback, which often fuels social withdrawal and anxiety.
MENTAL FILTERING
Focusing exclusively on the negative aspects of a situation while ignoring any positive elements. For example, a person receiving mixed feedback might only remember the criticism, overlooking praise or constructive comments.
DISQUALIFYING THE POSITIVE
Rejecting positive experiences by insisting they don’t count. For instance, someone might attribute their success to luck rather than recognising their skills or effort.
"SHOULD" STATEMENTS
Imposing rigid expectations on oneself or others, leading to guilt or frustration when these expectations are not met. For example, thinking, "I should always succeed," and feeling like a failure when encountering difficulties.
EMOTIONAL REASONING
Believing that feelings must reflect objective reality. For example, if a person feels worthless, they believe they must actually be worthless, regardless of any evidence to the contrary.
LABELLING AND MISLABELLING
Assigning global, negative labels to oneself or others based on specific incidents. For example, calling yourself "stupid" after making a mistake, overlooking any evidence of intelligence or competence.
MAGNIFICATION (CATASTROPHISING) AND MINIMISATION
Exaggerating negative aspects (magnification) while downplaying positive ones (minimisation). For example, seeing a minor mistake as catastrophic while ignoring significant achievements.
JUMPING TO CONCLUSIONS
Making negative interpretations without evidence. This includes:
Mind Reading: Assuming others are thinking negatively about you.
Fortune Telling: Predicting negative outcomes without any real evidence.
CONTROL FALLACIES
Believing you have either total control or no control over a situation. For example, an external control fallacy makes someone feel powerless, while an internal control fallacy involves assuming responsibility for everything, even things beyond one’s control.
FALLACY OF FAIRNESS
Expecting that life or situations should always be fair, and feeling resentful when they are not. This can lead to frustration, as life is rarely as fair as we might wish.
BLAMING
Blaming others for one’s problems or blaming oneself for things outside one’s control. This prevents individuals from taking responsibility for their own emotions and actions.
FALLACY OF CHANGE
Believing that others must change their behaviour to suit your needs, leading to frustration when others don’t meet these expectations. This can result in a lack of personal responsibility for one’s own happiness.
GLOBAL LABELLING (GLOBAL JUDGEMENT)
Making broad negative judgements about oneself or others based on limited information. For example, calling yourself "a failure" based on one setback, ignoring other successes.
ALWAYS BEING RIGHT
Believing that your views are always correct, and needing to prove this at any cost, often leading to conflicts with others and a lack of openness to other perspectives.
HEAVEN’S REWARD FALLACY
Believing that self-denial or sacrifice will inevitably lead to rewards. When these rewards do not materialise, the person may feel bitter or resentful.
These cognitive distortions can significantly impact mental health, reinforcing negative self-schemas and maladaptive behaviours. In CBT, individuals learn to identify and challenge these distorted thoughts, helping to break the cycle of negative thinking and improve emotional wellbeing.
ANTECEDENT BELIEF CONSEQUENCE: THE ABCs
A – ACTIVATING EVENT: This pertains to any trigger or occurrence within the environment, such as receiving a negative assessment of one’s work.
B – BELIEFS: The focus is on the individual’s perceptions about the event or circumstance. These beliefs may range from rational to irrational. For instance, an irrational belief might lead a person to see themselves as a failure. In contrast, a rational belief might encourage them to work harder to improve upon the negative feedback received.
C – CONSEQUENCE: This aspect deals with the result of the individual's belief, significantly impacting their emotional state and behaviour. Within the depression context, it predominantly refers to the emotional reaction elicited. Rational beliefs are often associated with healthy emotional responses, while irrational beliefs can provoke unhealthy emotions, potentially resulting in depression.
For instance, consider the scenario where an individual receives criticism at work (Activating Event). Suppose they harbour the irrational belief (Belief) that they must be perfect in all aspects of their job to be valued or respected. In that case, this can lead to feelings of worthlessness and inadequacy (Consequence), potentially spiralling into depressive symptoms. This example illustrates how Ellis’ model captures the cognitive pathway from a triggering event through a distorted belief system to the emotional and behavioural consequences that characterize depression.
ELLIS’ ABC MODEL EVALUATION
A notable strength of Ellis' ABC model lies in its practical application in real-world settings. By pinpointing thinking as the root cause of depression, cognitive-behavioural therapies (CBT) can effectively address these issues. There is also substantial research backing the cognitive underpinnings of depression. Studies, such as those by Evans et al., indicate that more intense negative thinking is closely linked with more severe forms of depression, characterized by maladaptive attitudes and beliefs. This lends credence to the ABC model's premise that irrational thinking is a primary contributor to depression. The efficacy of CBT in treating depression further reinforces the model's validity.
However, the ABC model faces criticism for seemingly attributing blame to patients for their disorders. It implies that the patient's irrational thoughts are self-generated, potentially disregarding the impact of their life situations. This perspective may oversimplify the complexity of depression by suggesting that individuals can 'think themselves better.'
Moreover, much of the supporting research for cognitive explanations is correlational, making it challenging to establish a clear causal relationship between negative cognitions and depression. This raises the question of whether such cognitive patterns are a cause or a symptom of depression.
An alternative explanation, such as the diathesis-stress model, might more accurately account for why certain individuals develop depression in response to negative thinking while others do not. This model suggests that a genetic predisposition, combined with specific environmental stressors, triggers the cognitive biases leading to depression. Biological evidence, including the association of depression with low serotonin levels, suggests that purely cognitive explanations may overlook underlying biological factors, indicating the complexity of depression extends beyond cognitive processes alone.
BECK’S NEGATIVE TRIAD
Beck's Negative Triad is a cognitive theory developed by Aaron Beck in 1967 to explain the underlying thought patterns contributing to depression. This model proposes that individuals with depression have a pessimistic view of themselves, the world, and the future. These negative views are interrelated and reinforce one another, creating a cycle that perpetuates depressive symptoms. Beck's Negative Triad consists of three main components:
Negative View of the Self: Individuals see themselves as deficient, inadequate, or unworthy. They often believe they are flawed or have insurmountable weaknesses, leading to helplessness and low self-esteem.
Negative View of the World: People perceive their environment and life experiences through negativity. They might feel that the world is an unfair, hostile place and that they face insurmountable obstacles. This view reinforces the idea that achieving happiness or success is impossible.
Negative View of the Future: There is a pervasive belief that the future holds no hope for improvement, happiness, or success. Individuals expect that difficulties will continue or worsen, leading to a sense of despair and hopelessness.
According to Beck, these three components interact to maintain and exacerbate depressive states. For example, a negative view of the self may lead to the belief that one cannot face life's challenges, which feeds into the perception that the world is overwhelmingly difficult and that the future will be bleak. This triad of negative beliefs influences how individuals interpret their experiences, often leading them to overlook positive aspects of their lives and interpret ambiguous situations negatively.
Beck's Negative Triad has been influential in the development of Cognitive Behavioural Therapy (CBT) for depression. CBT aims to identify, challenge, and modify the distorted beliefs and negative thinking patterns characteristic of the Negative Triad, helping individuals adopt a more balanced and realistic view of themselves, their experiences, and their prospects
SIMILARITIES AND DIFFERENCES BETWEEN THE TWO COGNITIVE MODELS
The ABC Model by Albert Ellis and Beck's Negative Triad are both cognitive frameworks used to understand and treat depression, with several similarities and differences in their approach and focus:
Similarities:
Cognitive Basis: Both models emphasize the role of cognitive processes in developing and maintaining depression. They suggest that it is not the events themselves but the interpretation of these events that leads to depressive feelings and behaviours.
Therapeutic Application: Each model has been foundational in developing Cognitive Behavioral Therapy (CBT) techniques. They provide a structure for identifying and challenging negative thought patterns to alleviate depressive symptoms.
Negative Thinking Patterns: Ellis's ABC Model and Beck's Negative Triad highlight the significance of negative thinking patterns. Ellis focuses on irrational beliefs (B) following an activating event (A) leading to negative consequences (C). At the same time, Beck’s model outlines a general pattern of negative views towards oneself, the world, and the future.
DIFFERENCES
Structural Focus: The ABC Model explicitly outlines a process or sequence (Activating event, Belief, Consequence) that leads to depressive emotions and behaviours, suggesting a more dynamic interaction between events and beliefs. In contrast, Beck's Negative Triad provides a thematic categorization of negative thoughts without explicitly linking them to specific sequences or triggers.
Scope of Negative Beliefs: Beck's Negative Triad specifically targets three areas of negative thinking (self, world, future), providing a focused lens on the thematic areas where depressive individuals have distorted views. Ellis's ABC Model, however, is broader and can apply to any irrational belief about any event, making it more versatile in identifying a wide range of cognitive distortions.
Irrational vs. Negative Beliefs: Ellis's model strongly emphasizes the irrationality of beliefs (B) and how they can be contested and restructured. Beck's model, while also concerned with distorted thinking, tends to focus more on the negativity of the beliefs within the triad, regardless of whether they are irrational or simply pessimistic.
Application Beyond Depression: While both models are used to understand and treat depression, Ellis's ABC Model is also a foundational element of Rational Emotive Behavior Therapy (REBT) and is applied to a variety of psychological disorders beyond depression, emphasizing its applicability to a broader range of emotional issues. Beck's Negative Triad is primarily focused on depression.
In summary, while both Ellis's ABC Model and Beck's Negative Triad share a cognitive perspective on depression, emphasizing the role of negative thinking patterns, they differ in their structure, focus, and the scope of negative beliefs they address. These differences highlight the unique contributions each model makes to understanding and treating depression within cognitive behavioural therapy.

EVALUATION
SPECIFIC TO THE ABC MODEL
A notable strength of Ellis' ABC model lies in its practical application in real-world settings. By pinpointing thinking as the root cause of depression, cognitive-behavioural therapies (CBT) can effectively address these issues. There is also substantial research backing the cognitive underpinnings of depression. Studies, such as those by Evans et al., indicate that more intense negative thinking is closely linked with more severe forms of depression, characterized by maladaptive attitudes and beliefs. This lends credence to the ABC model's premise that irrational thinking is a primary contributor to depression. The efficacy of CBT in treating depression further reinforces the model's validity.
CONTROL FALLACIES: The ABC Model provides a structured framework for understanding how beliefs about control influence emotions and behaviours. However, it may oversimplify complex psychological processes related to control, such as learned helplessness or locus of control.
FALLACY OF FAIRNESS: The model effectively highlights how beliefs about fairness can impact emotional responses. However, it may not fully address the cultural or contextual factors that shape individuals' perceptions of fairness.
BLAMING: The ABC Model acknowledges the role of attributions in emotional experiences. However, it may overlook the nuances of blame-shifting dynamics and the influence of social factors on attributions.
SHOULDS: By recognising the role of rigid rules and expectations, the ABC Model emphasises the importance of flexible thinking patterns. However, it may not fully capture the cognitive and emotional complexities underlying "should" statements.
JUMPING TO CONCLUSIONS: While the model acknowledges cognitive biases like jumping to conclusions, it may benefit from a more comprehensive exploration of specific cognitive distortions and their underlying mechanisms
SPECIFIC TO THE BECK’S TRIAD MODEL
CONTROL FALLACIES: Beck's Triad Model offers insights into how negative beliefs about control contribute to depression and other psychological disorders. However, it may overlook the reciprocal relationship between control beliefs and emotional experiences.
FALLACY OF FAIRNESS: The model emphasises negative views about the world, including perceptions of unfairness. However, it may not sufficiently address individual differences in perceptions of fairness or the impact of cultural factors.
BLAMING: Beck's model recognises negative self-attributions as a core feature of depression. However, it may not fully explore the interpersonal dynamics of blaming and the role of social factors in shaping self-blame.
SHOULDS: Similar to the ABC Model, Beck's Triad Model highlights the role of rigid rules and expectations. However, it may not explicitly address the cognitive and emotional consequences of "should" statements.
JUMPING TO CONCLUSIONS: Beck's model acknowledges cognitive distortions like jumping to conclusions as part of negative thinking patterns. However, it may benefit from a more detailed examination of specific cognitive biases and their implications for psychological interventions.
SPECIFIC TO BOTH MODELS
one of the significant criticisms directed towards cognitive models of depression, including the ABC Model and Beck's Triad Model, is their perceived tendency to attribute blame to individuals for their disorders. These models highlight the role of irrational or negative thoughts in the development and maintenance of depression, potentially overlooking the broader contextual factors that contribute to mental health difficulties.
The emphasis on individuals' cognitive processes may inadvertently suggest that depression is solely a result of self-generated irrational thoughts, disregarding the impact of external life situations and systemic factors. This perspective oversimplifies the complexity of depression by implying that individuals can "think themselves better," which may not always be the case.
Indeed, there are numerous external factors, such as socioeconomic inequalities, discrimination, trauma, and systemic injustices like laws, sexism, homophobia, and racism, which can profoundly influence mental health outcomes. For example:
Structural Constraints: People may be restrained by societal structures, laws, and policies that limit their opportunities and exacerbate stressors. Discriminatory practices and systemic inequalities can significantly impact mental health, creating barriers to accessing resources and support.
Traumatic Events: Certain life events, such as the death of a child, forced marriage, or a history of abuse, can have profound and lasting effects on an individual's mental well-being. These traumatic experiences can contribute to the development of depression and other mental health disorders, regardless of an individual's cognitive processes.
Cultural and Social Contexts: Cultural norms and societal expectations play a crucial role in shaping individuals' experiences and expressions of distress. Cognitive models may not adequately account for cultural variations in coping mechanisms, beliefs about mental health, and help-seeking behaviors.
Therefore, it's essential to recognize that while cognitive processes play a significant role in depression, they are only one piece of the puzzle. Effective understanding and treatment of depression require a comprehensive approach that considers the multifaceted interplay between cognitive, biological, social, and environmental factors. By acknowledging the broader context in which depression arises, mental health professionals can provide more holistic and culturally sensitive care that addresses the diverse needs of individuals experiencing depression
Much research supporting cognitive models, such as Beck's Triad Model, relies on correlational evidence. This means that while negative cognitions often co-occur with depression, it's difficult to determine whether these cognitive patterns directly cause depression or if they are a symptom or consequence of depression.
Several factors contribute to this challenge:
Bidirectional Relationship: Depression and negative cognitions likely influence each other in a bidirectional manner. Negative thoughts can contribute to the onset and maintenance of depressive symptoms, while depression itself can also exacerbate negative thinking patterns.
Depression as a Symptom, Not a Cause: Critics question whether negative cognitions identified in cognitive models are the cause of depression or merely a symptom. They argue that focusing solely on cognitive factors may overlook underlying causes of depression, such as trauma or neurochemical imbalances.
Third Variables: Other factors, such as genetic predispositions, environmental stressors, and personality traits, may influence both cognitive patterns and depression. Disentangling the effects of these variables from cognitive processes can be complex.
Methodological Limitations: Correlational studies often cannot establish causality due to their observational nature. Longitudinal studies and experimental designs are better suited for investigating causal relationships, but they can be challenging to conduct in depression research.
Clinical Implications: Despite the difficulty in establishing causality, cognitive therapies based on these models have shown effectiveness in treating depression. This suggests that addressing negative cognitions can lead to improvements in depressive symptoms, regardless of whether they are a cause or a consequence of depression.
Simplicity Oversimplifies Complexities: Critics argue that cognitive models, such as Beck's Triad Model, oversimplify the multifaceted nature of depression. They may neglect the influence of biological, social, and cultural factors on depression, focusing solely on cognitive processes.
Cognitive Bias in Research: Some critics suggest that researchers in the cognitive paradigm may have a cognitive bias themselves, leading to an overemphasis on cognitive factors in understanding depression while neglecting other important factors.
Individual Differences Ignored: Cognitive models often assume uniformity in cognitive processes across individuals. However, critics argue that people have unique cognitive styles and coping mechanisms, which these models may not adequately address.
Limited Predictive Power: Cognitive models may struggle to predict who will develop depression and why, particularly in cases where there are no identifiable negative cognitions present beforehand.
Treatment Implications: While cognitive therapies based on these models have shown effectiveness, critics argue that they may not address the root causes of depression for all individuals. Some people may require interventions that target biological or environmental factors rather than cognitive processes alone.
Cultural Considerations: Cognitive models of depression may not adequately account for cultural variations in cognitive styles and expressions of distress. What constitutes negative thinking or maladaptive beliefs may vary across cultures.
CLINICAL APPLICATION: Both models have been widely used in clinical practice to understand and treat psychological disorders. However, they may not address the diverse range of individual experiences or incorporate recent advances in cognitive and affective neuroscience.
CULTURAL SENSITIVITY: While both models acknowledge the influence of sociocultural factors on cognitive processes, they may not fully account for cultural variations in cognitive styles and emotional expression.
An alternative explanation, such as the diathesis-stress model, might more accurately account for why certain individuals develop depression in response to negative thinking while others do not. This model suggests that a genetic predisposition, combined with specific environmental stressors, triggers the cognitive biases leading to depression. Biological evidence, including the association of depression with low serotonin levels, suggests that purely cognitive explanations may overlook underlying biological factors, indicating the complexity of depression extends beyond cognitive processes alone.
COGNITIVE APPROACH TO TREATING DEPRESSION
OVERVIEW OF CBT
Cognitive psychologists focus on how people perceive, anticipate, and evaluate events rather than the events themselves. For example, consider how someone perceives exams. It is not the exam itself that causes anxiety or stress, but how the individual anticipates and evaluates the experience of taking the exam. If someone holds optimistic or realistic cognitions, they are more likely to approach exams with a healthy mindset, even in the face of failure.
The central premise of CBT is that cognitions influence behaviour: healthy cognitions result in adaptive behaviour, while faulty cognitions lead to maladaptive behaviours, emotions, and perceptions. This concept is sometimes referred to as a self-fulfilling prophecy — the idea that "you are what you think." In other words, the way individuals think about themselves and the world around them significantly impacts how they feel and behave.
Ultimately, CBT is a form of psychotherapy that helps patients recognise and challenge distorted thinking patterns and beliefs. Through guided questioning and self-reflection, patients learn to replace these unhealthy thoughts with more constructive ways of thinking and behaving. By addressing both the cognitive and behavioural aspects of their issues, individuals can develop healthier responses to the challenges they face in daily life.
COGNITIVE BIASES AND NEGATIVE SCHEMAS IN MENTAL ILLNESS
Cognitive biases are systematic errors in thinking that affect how we perceive and interpret situations. These distorted thought patterns often lead to negative emotions and behaviours, contributing to mental illnesses such as depression, anxiety, and schizophrenia. When a person consistently interprets their experiences through a distorted lens, they are more likely to develop negative self-beliefs and maladaptive behaviours.
Negative schemas are deeply ingrained negative beliefs about oneself, others, or the world. These schemas are often formed in childhood and are activated by stressful life events. For example, someone with a negative schema might believe they are unlovable or inadequate, and cognitive biases reinforce these negative beliefs. Together, cognitive biases and negative schemas create a cycle of distorted thinking that worsens mental health conditions, making them a key focus in Cognitive Behavioural Therapy (CBT).
These cognitive distortions not only distort how we see ourselves and the world but also fuel negative schemas, deepening mental health issues. By identifying and challenging these biases through CBT, individuals can break the cycle of negative thinking and develop healthier thought patterns.

PERSONALISED AND COLLABORATIVE PROCESS
CBT is highly collaborative. At the start of each session, the therapist and client create a session agenda to decide what will be discussed. Together, they also study the client’s symptoms and explore potential triggers and solutions, identifying what worsens or alleviates symptoms. A crucial part of CBT is homework, where the client practices a skill learned during the session in real-life situations between appointments.
SPECIALISED TECHNIQUES
The CBT therapist uses a variety of specialised techniques to help clients identify unhelpful thoughts (or “cognitions”) and teaches them skills to modify these maladaptive cognitions over time. For example, a client who feels worthless might work on identifying this thought, questioning its validity, and replacing it with more balanced and rational beliefs.
In addition to cognitive restructuring, the therapist helps the client evaluate their current coping strategies for managing stress, paranoia, voices, depression, or anxiety. Through a process of trial and error, the therapist and client optimise coping strategies, determining what works best and adjusting accordingly.
THE PAST OR PRESENT ?
CBT presumes that a person’s symptoms are not random or purely “biological” in nature but are closely related to their psychology and personal experiences, often carrying significant meaning. For instance, CBT theory suggests that if a person hears voices telling them they are a terrible person, it is not a random occurrence. This may be tied to past experiences where the person was told they were worthless, and their current voices are a reflection of their internal struggle with feelings of inadequacy or worthlessness.
BECK’S TRIAD AND ELLIS’S ABC
Cognitive behavioural therapy (CBT) is the main psychological treatment used to treat people suffering from depression and was first introduced by Ellis as REBT (rational emotive behavioural therapy).
CBT assumes that maladaptive thoughts and beliefs cause and maintain depression in individuals.
CBT focuses on helping patients identify and change these maladaptive thought processes. It believes that changing thinking will then change behaviour and emotions, as these are seen to be generated by thinking.
The idea is that individuals have beliefs, expectations and cognitive assessments of themselves, the environment and the irrational problems they face. By replacing these with more positive and productive thinking and behaviour, emotions will also become more positive, breaking the depressive cycle.
The behavioural element involves encouraging the patient to engage in rewarding experiences and activities in the hope that their thoughts will become more positive. The treatment is usually short, between 16 and 20 sessions, and two of the main techniques often used are “challenging irrational thoughts” and “Behavioural activation.”
By challenging their irrational thoughts, patients learn to see the link between how their thinking affects their emotions and to record any emotionally arousing events (or activating events) that may occur. They then think about the negative thoughts associated with this event and are encouraged to challenge them with more positive thoughts. They do this by questioning whether what they think is logical and makes sense, whether it is empirical and has evidence and whether the thought is pragmatic and helpful.
Through this type of thinking, patients are taught to become more objective and replace dysfunctional thoughts with constructive ways of thinking, which should improve their emotional state, too.
Behavioural activation is based on the idea that being active will lead to more positive rewards that will help alleviate depressive symptoms. Many depressed people become withdrawn and do not engage in previously pleasurable activities. With the therapist's help, the patient identifies enjoyable activities and encourages the patient to challenge any negative thoughts they may have regarding them to help them become active again.
EVALUATIVE POINTS FOR CBT AND DEPRESSION
ADVANTAGES
EMPOWERMENT AND SELF-MANAGEMENT: CBT empowers individuals to take an active role in managing their mental health. By teaching patients coping skills and strategies to identify and challenge negative thought patterns, CBT promotes self-awareness and self-efficacy in dealing with depressive symptoms.
VERSATILITY AND ADAPTABILITY: CBT is a flexible treatment approach tailored to individual patient's unique needs and preferences. Therapists can adapt CBT techniques to accommodate cultural differences, developmental stages, and comorbid conditions, making it suitable for diverse populations.
PREVENTION OF RELAPSE: CBT is effective in preventing relapse in individuals who have recovered from depression. Through continued practice of coping skills and relapse prevention strategies learned in therapy, patients can better manage stressors and early signs of recurrence, reducing the likelihood of depressive relapse.
INTEGRATION WITH OTHER THERAPEUTIC APPROACHES: CBT can be integrated with other therapeutic modalities, such as mindfulness-based interventions or interpersonal therapy, to enhance treatment outcomes. Combining different approaches allows therapists to address a broader range of factors contributing to depression and offer more comprehensive care.
LONG-TERM BENEFITS: Research suggests that CBT for depression can extend beyond the completion of therapy sessions. Patients may experience sustained improvements in mood, functioning, and overall well-being, leading to better long-term outcomes than medication alone.
COST-EFFECTIVENESS: Despite the initial investment of time and resources required for CBT, studies have shown that it can be cost-effective in the long run. By reducing the need for ongoing medication management and healthcare utilization associated with untreated depression, CBT may result in significant cost savings for individuals and healthcare systems.
POTENTIAL FOR DIGITAL AND REMOTE DELIVERY: Advances in technology have expanded the accessibility of CBT through digital and remote delivery methods. Online CBT platforms, mobile applications, and teletherapy services offer convenient and scalable options for individuals seeking evidence-based treatment for depression, overcoming barriers related to geographical distance and scheduling constraints.
CONSIDERATIONS FOR TREATMENT RESISTANCE: While CBT is effective for many individuals with depression, some patients may not respond adequately to standard CBT protocols. In such cases, clinicians may need to explore alternative treatment approaches or modifications to CBT techniques to address underlying factors contributing to treatment resistance.
A strength of CBT that makes it more appropriate and effective is that the therapy has no side effects, unlike drug therapies. Drugs can have severe side effects affecting the heart and have even been linked to suicides and murder. Some drug therapies require patients to avoid certain foods, such as cheeses and wines, which can have adverse and fatal reactions. For patients suffering from health conditions or those who are unable to make such lifestyle changes, CBT may be more appropriate for them.
NO SIDE EFFECTS
Another notable strength of CBT is its focus on addressing the root cause of depression, which is often psychological. In contrast, drug therapies may primarily alleviate symptoms without targeting the underlying issues. Consequently, CBT is viewed as a more curative and holistic approach, with benefits expected to be longer-lasting. Unlike medication, which typically remains effective only as long as it's taken, CBT's effects are believed to persist beyond the treatment period. Follow-up studies, including research by Evans et al., have reported lower relapse rates with CBT than other treatments, further highlighting its effectiveness.
Moreover, CBT doesn't pose concerns related to addiction or dependency, which can be associated with antidepressant medications. This aspect makes CBT particularly suitable for patients with a history of drug dependency issues, as it offers a safer and more appropriate treatment option.
SUPPORTING RESEARCH
The effectiveness of Cognitive Behavioral Therapy (CBT) in treating depression has been the subject of various studies, each providing valuable insights into its efficacy and potential applications.
A study conducted by Rush et al. demonstrated that CBT is comparably effective to antidepressants in treating depression. This suggests that CBT can offer similar benefits in alleviating depressive symptoms, providing patients with an alternative treatment option.
On the other hand, research by Keller et al. suggests that CBT may be most effective when used in conjunction with antidepressant medication. This combination approach could potentially enhance treatment outcomes, offering patients a more comprehensive and integrated approach to managing their depression.
Whitfield and Williams highlighted the robust research base supporting the effectiveness of CBT. However, they also acknowledged challenges in delivering traditional face-to-face CBT sessions, particularly in light of current healthcare budget constraints. Despite this, the study underscores the potential for real-world applications of CBT through self-help interventions.
One example of such an application is the SPIRIT course, which aims to teach core cognitive-behavioural skills through self-help materials. By offering self-directed CBT resources, such as online courses or workbooks, individuals can access evidence-based treatment strategies at their convenience, potentially overcoming barriers related to cost, time, and accessibility.
In summary, these studies' findings highlight CBT's versatility and potential in treating depression. Whether used alone, in combination with medication, or through self-help interventions, CBT offers a valuable therapeutic approach for individuals seeking relief from depressive symptoms.
DISADVANTAGES OF CBT FOR DEPRESSION
TIME AND COST FACTORS: CBT often requires multiple sessions with a trained therapist, which can be time-consuming and costly. Unlike drug therapies, which involve simply taking medication, CBT demands a significant investment of time and financial resources. For individuals with limited time or financial constraints, accessing CBT may be challenging or even unaffordable, making it inappropriate for some patients.
PREFERENCE FOR DRUG THERAPIES: Some patients may prefer drug therapies over CBT due to their simplicity and convenience. Taking medication does not require the same level of engagement or sharing of intimate feelings as CBT sessions with a therapist. This preference may be especially pronounced in individuals who are uncomfortable discussing their emotions with a stranger or prefer a more passive approach to treatment.
SEVERITY OF WITHDRAWAL AND ENGAGEMENT ISSUES: For patients who are severely withdrawn or have difficulty engaging with others, CBT may be inappropriate or even detrimental. The requirement to actively participate in therapy sessions and engage in cognitive restructuring exercises may feel overwhelming for these individuals, potentially reinforcing their feelings of isolation and hopelessness.
POTENTIAL TO STRENGTHEN DEPRESSIVE SYMPTOMS: In some cases, attempting CBT with patients who are severely withdrawn or struggling to engage with others may backfire. Feeling overwhelmed or disappointed by the therapy process may exacerbate depressive symptoms rather than alleviate them. This could lead to a worsening of the individual's mental health and make CBT ineffective or inappropriate for these patients.
EFFECTIVENESS HINGES ON THERAPIST COMPETENCE: Another factor affecting CBT's efficacy is therapists' proficiency. The effectiveness of CBT hinges on the therapist's ability to establish a collaborative relationship with the patient and apply the techniques adeptly. Therapists vary in enthusiasm and competence, potentially impacting the therapy's success. According to Kuyken et al., up to 15% of the variance in outcomes can be linked to therapists' competency levels, underscoring the importance of therapist skill in CBT's effectiveness.
LIMITED ACCESSIBILITY: While CBT can be highly effective, access to qualified CBT therapists may be limited in some regions or healthcare systems. Long waitlists or high costs for private therapy sessions can hinder individuals from accessing timely treatment.
RESISTANCE AND DROP-OUT RATES: Some patients may initially resist or struggle to engage with CBT due to the confrontational nature of cognitive restructuring or behavioural interventions. This can lead to high dropout rates and limited effectiveness for those who are unable to commit to the therapy process fully.
RELIANCE ON SELF-REPORTING: CBT heavily relies on patients' self-reporting of thoughts, feelings, and behaviours. However, individuals may inaccurately recall or misinterpret their experiences, leading to potential biases or inaccuracies in therapy progress assessments.
INEFFECTIVENESS FOR SEVERE CASES: While CBT is generally effective for mild to moderate depression, it may be less effective for individuals with severe or treatment-resistant depression. These individuals may require more intensive or specialized interventions, such as medication or electroconvulsive therapy, to achieve symptom relief.
LIMITED FOCUS ON UNDERLYING TRAUMA: CBT primarily targets cognitive and behavioural patterns associated with depression but may overlook underlying trauma or unresolved emotional issues contributing to the condition. For individuals with a history of trauma or complex psychological needs, alternative therapies or adjunctive interventions may be more appropriate.
CULTURAL AND LINGUISTIC BARRIERS: Cultural and linguistic differences between therapists and patients can pose challenges in CBT delivery, affecting treatment rapport, understanding, and effectiveness. Therapists may need to adapt their approach to accommodate diverse cultural perspectives and communication styles.
TIME AND COMMITMENT REQUIREMENTS: Successful CBT outcomes often require consistent attendance, active participation in therapy sessions, and ongoing practice of learned skills outside of sessions. This time and commitment may be challenging for individuals with busy schedules or competing priorities, leading to limited engagement and suboptimal treatment outcomes.
POTENTIAL FOR OVEREMPHASIS ON POSITIVE THINKING: Some critics argue that CBT's focus on challenging negative thoughts and promoting positive thinking may inadvertently dismiss or invalidate the validity of individuals' genuine emotions and experiences. This emphasis on positive thinking alone may not address deeper psychological issues or existential concerns underlying depression.
