, Cognitive vulnerability-stress models of depression – Ambramson
Why some people are vulnerable to depression whereas other not? According to BOTH
theories, the meaning/interpretation that people give to their experiences influence
this
Hopelessness Theory Beck’s Theory
Inference Stable-global causes
s Future negative consequences
Negative self-characteristics
Event Negative cognitive Event Negative cognitive
style (inferences) schema/dysfunctional attitudes
Hopelessness Symptoms Cognitive distortions Negative
cognitive triad (yourself, world and
future) Symptoms
Moderato Social support, material,
rs emotional and informational
support
Depressed people inferences are Depressed people inferences are
negative negative and distorted
Similarities
- Role of cognition in the origins and maintenance of depression
- Cognitive vulnerability component moderating the effects of negative events on
depression
- Mediating sequence of negative inferences (hopelessness/negative cognitive
triad)
- Heterogeneity of depression
Differences
- Cognitive process (encoding, retrieval, attention)
- Cognitive products (cognitions about causes and consequences)
Hopelessness = Depressive & non cognition differ in content but not in process
Beck’s = Depressive & non cognition differ in content AND process
Cognitive theories explain the big facts of depression:
- Depression is recurrent
- Life events play a role in the development of depression
- Depression can be lethal (as increase the risk for suicide)
- Depression is a common disorder
- Depression peaks during middle to late adolescence
- There are gender differences where women show elevation in interpersonal
domain and negative cognitive styles (Abramson) while men on dysfunctional
attitudes (Becks)
- Depression is heterogenous with multiple causes
Assumptions of contemporary integrative interpersonal theory –
Hopwood
Contemporary integrative interpersonal theory (CIIT)
Personality and psychopathology manifest in interactions
with others
Psychopathology = Someone acts different than expected
o Agency (vs passivity) & communion (vs
dissociations)
o Levels = Motives, traits, behaviours
Motive = Be in control – Be close
Trait = Dominance – Nurturance
Behaviour = Directive – Friendly
