Cognitive Model of Depression
Beck et al. (1979) · Depression
Written by Tarun Vermani, Trainee Clinical Psychologist Last reviewed
Beck's cognitive model of depression (Beck, Rush, Shaw and Emery, 1979) traces low mood from early experience through core beliefs and rules to the negative automatic thoughts of the cognitive triad, and on into withdrawal.
Cognitive Model of Depression
Beck et al. (1979)
Early Experiences
Early experiences that shape beliefs about the self — loss, rejection, harsh or conditional criticism, neglect, or unfavourable comparison, often in childhood.
Core Beliefs / Schemas
Negative core beliefs (schemas) laid down by those experiences — e.g. 'I'm unlovable', 'I'm worthless', 'I'm helpless / inadequate'. They can stay latent until something activates them.
Dysfunctional Assumptions & Rules
Dysfunctional assumptions and rules developed to live with the core belief — 'if I succeed at everything, I'm OK', 'unless everyone likes me, I'm worthless', 'I must not show weakness'.
Critical Incident
A critical incident that breaks an assumption, or echoes the original experience — a loss, failure, rejection or setback — activating the dormant core belief.
Negative Automatic Thoughts (Cognitive Triad)
Negative automatic thoughts, patterned by Beck's cognitive triad — a negative view of the self ('I'm a failure'), of the world and current experience ('nothing works out') and of the future ('it will never change') — and shaped by cognitive distortions (all-or-nothing thinking, overgeneralisation, magnification, discounting the positive).
Symptoms of Depression
The symptoms of depression that follow — low and hopeless mood, loss of pleasure and motivation, withdrawal and reduced activity, fatigue, disturbed sleep and appetite, poor concentration. These feed back to reinforce the negative thoughts and confirm the core belief.

Understanding the model
When we're depressed, the way we think turns sharply against us. Beck's cognitive model shows how this negative thinking develops — from early experiences right through to the low mood of today — and how it keeps itself going.
Early experiences can lay down deep beliefs about ourselves — for example 'I'm not good enough' or 'I'm unlovable'. These beliefs can sit quietly in the background for years. To cope, we build rules to live by, like 'as long as I succeed, I'll be OK'.
Later, a setback that breaks one of those rules — a loss, a failure, a rejection — can wake the old belief up. Once it's active, the mind produces a stream of harsh automatic thoughts that fall into Beck's 'negative triad': a bleak view of yourself, of the world around you, and of the future.
Those thoughts pull mood down, drain energy and motivation, and lead us to withdraw and do less — which then seems to prove the thoughts right, so low mood and negative thinking keep each other going. Seeing the whole chain shows where therapy can step in.
Questions therapists ask about this model.
Frequently asked questions
What does this model say maintains depression?
Early experiences can lay down deep beliefs about the self, and rules for living are built to keep them out of view. A setback that breaks one of those rules reactivates the belief, and a stream of negative automatic thoughts follows, patterned by the cognitive triad — a bleak view of the self, of current experience and of the future. Those thoughts lower mood and energy and lead to doing less, which then appears to confirm them, so thinking and mood hold each other in place.
How does it differ from the behavioural activation model?
This is a longitudinal account that carries the developmental layer — early experience, core beliefs, rules — and places thinking at the centre. Lewinsohn's behavioural model of depression, from which modern behavioural activation (Jacobson, Martell and colleagues) developed, works at the level of behaviour and its consequences: withdrawal removes the sources of reward, and mood falls further as a result. Both are formulated for depression, which NICE NG222 covers, and they describe the same picture at different levels.
How has the model developed since it was first described?
Beck's first full account (1967) drew on clinical, experimental and theoretical work on depression, and the 1979 book with Rush, Shaw and Emery set the model out in the form used here. Clark, Beck and Alford (1999) reviewed the scientific foundations of its central claims, and Beck (2008) traced how the model had evolved and how it relates to later findings on the neurobiology of depression.
