Beck’s cognitive theory
negative interpretations and thoughts = depression; lack of positivity bias; less access to positive thoughts
Beck’s cognitive theory
diathesis: formation of dysfunctional beliefs// stressor: critical incident > activates beliefs> automatic thoughts result> depressive symptoms
negative cognitive triad
self: I’m unloveable/ world: no one loves me// no one will ever love me
helplessness theory
learned helplessness// depressive attributional style// negative outcomes are ones fault// stable attributions/ future negative outcomes will be one’s fault// global attributions/ negative events disrupt life events/ hopelessness//
helplessness theory:
uncontrolled event/ sense of helplessness/ emerging depression
hopelessness theory
uncontrolled event/ sense of hopelessness/ emerging depression/
hopelessness theory
explains comorbidity between anxiety and depression: helplessness = anxiety// helplessness+ hopeless = depression
helpless/hopeless
pessimism/ diathesis/ will not result in depression unless experiences hopelessness

“I failed because I am no good”: I always fail” (a stable attribution). “I fail in everything”( global)
depression attributions: internal
if someone loses a job, and they
attribute it to some failing on their part (internal),
see things as similarly not working out for them
in other areas (global), and see a long term
pattern of failure and disappointment in the
future (stable) they are likely to become
depressed.
