  • Outcomes independent of behaviour

Q

Abramson’s hopelessness theory

A 
Attributions of negative events are:
- Stable,
- Internal,
- Global
Helplessness was driven not by how people perceived the relationship between actions and outcome, but by how they explained the situation / incident to themselves

Q

Basic Cognitive Model (Beck)

A

Situation –> Automatic thoughts –> reaction
Example:
Difficult reading material for class –> I don’t understand, I’m so stupid –> Sad, turn on TV for comfort
OR
Difficult material –> awesome! deep material –> studies hard/excited

Q

Automatic thoughts

A
  • Specific to situations – they come from core beliefs or cognitive schemas
  • stream of positive or negative thoughts; unconscious
  • NOT RANDOM*
  • Surface level cognitiion

Q

Core Beliefs/Cognitive Schemas

Depressive Schema

A
  • Organized structures of stored information that contain individuals’ perceptions of self and others, goals, expectations and memories
  • Rigid, generalizable, developed during childhood, absolute truth for the person, influence information processing

Enduring, rigid, and complex negative beliefs about the self, world, and future that are resistant to change despite the presentation of disconfirming information.

Q

Automatic thought vs. Core Beliefs

A

Automatic is situation specific and come from schemas

Core beliefs/schemas are rigid and generalizable, developed in childhood

Q

Levels of Depressotypic Cognition

A
  • Core Beliefs/Schemas (ex: “I’m a failure”) –>
  • Intermediary beliefs/assumptions (rules, attitudes, assumptions) (ex:“I must do everything right, otherwise I’m a total failure”) –>
  • Automatic Thoughts (e.g., I never can do anything right)–>
  • Situation (e.g. receive a bad grade) –>
  • Sadness

Q

Original Model

A

Adverse developmental experiences –> dysfunctional attitudes (schemas); cognitive vulnerability –> activation by stressful events –> pervasive negative cognitive bias; depression

Q

Cognitive Distortions

A

All-­or-­nothing thinking: concrete rather than on continuum
Catastrophizing: predicting the future negatively without
considering more likely outcomes
Discounting the positive
Emotional reasoning: associating truth with the intensity of emotion
Magnification/minimization: of the negative/positive aspects of situations.
Selective Abstraction/mental filter: focus on one detail at
the expense of others.
Mind-­‐reading: You believe what others are thinking and not considering other possibilities.
Personalization: attributing cause of external events
to inherent weakness or inadequacy while disregarding
contradictory evidence

Q

STUCTURE OF CBT

A
  • Early sessions: assessment and conceptualization; goal setting
  • Middle sessions: Cognitive (and behavioral) interventions
  • Late sessions: evaluation, relapse prevention

Q

STUDY: Temple-Wisconsin Cognitive Vulnerability to Depression

A

Retrospective:

  • HR (high-risk individuals) were twice more likely to report a history of depression in the past - But no differences in rate of anxiety
  • Causal direction between cognitive vulnerability to depression and lifetime depression is unclear

Prospective:
- Participants without a depression:
•HR had greater likelihood of having first episodes (later) - 17% vs. 1%
•No significant differences in risk for anxiety - 7% vs. 3%
- Participants with a depression
•HR had greater risk (more likely to have a NEW depression) -27% vs. 6%

Predictors of Relapse 
Lower age of onset 
Lifetime history of dysthymia 
Severity of the first episode 
Cognitive vulnerability is stable over time --> Did not change during episode of depression

Q

Cognitive Reactivity

A

Cognitive reactivity = fluctuations in person’s negative attitudes about themselves in response to daily negative events

Measured by self-report
- LEIDS or DSC

17
Q

STUDY: cognitive reactivity as a predictor of depression

Longitudinal data, Netherlands study of depression and anxiety; 2,891 participants, including people with lifetime history of depression/anxiety

They looked at predictors such as baseline/subthreshold symptoms, negative recent life events, anxiety, family history, LEIDS, gender, age, education

A

Results: LEIDS was a strong predictor, as well as sub threshold mood disorder symptoms and recent negative life events

18
Q

Autobiographical memory

A

memory concerned with life events

19
Q

Autobiographical Memory Test (AMT)

A

Ask to provide a specific memory to in response to a positive or negative word.
Ex: “Happy” is the key –> they respond with a specific memory of their birthday

** the event must be from a specific time and place and lasting less than 24hours (ex can’t say my childhood)

20
Q

Autobiographical memory and depression

A

Overgeneralized AMT response is predictor of depression after a negative life event.
Also seen in remitted patients and can predict the outcome/course of depression
Two kinds:
Categorical memory: class of similar events (ex: all my birthday parties)
Extended memory: events lasting more than a day (ex: walking my dog every morning)

21
Q

Why does overgeneralized AMT tests predict depression?

A

Possible Mechanisms:
Rumination interfering with retrieval process
Avoiding painful memories
Impaired executive control (lead to issues with problem solving)

22
Q

Study looking at AMT overgeneralization and 5-HTTLPR

A

Method: participants genotyped for s/s, s/l, l/l 5-HTTLPR gene. s/s and s/l at risk.

  • asked AMT questions
  • SCID interview

Results:
- More overgeneralized memories in those with a history of depression and s/s genotype
- Number of s alleles associated with greater number of specific memories in those without a history of depression
- Combination of MDD and s/s = lowest scores; no history of MDD and s/s = highest scores (better)
…….Why? Differential susceptibility hypothesis
• S/S are more sensitive to environment therefore, in negative environment do worse (therefore, MDD and bad AMT results) but in positive environment do better (therefore, no MDD and good AMT results)

23
Q

Describe another study looking at serotonin and cognitive vulnerability

A
  • eye tracking study- gaze bias
  • genotypes: serotonin transporter 1a or 2a, 5-HTTLPR
    o Calculate “genetic scores”; higher score, more at risk
    o Individuals with higher serotonin cumulative genetic score were significantly more likely to look towards dysphoric images and away from positive images as mood reactivity increased (lower moods)
    o Shows: cognitive and serotonin vulnerability may be related
24
Q

How does normal sadness effect vulnerable individuals?

A

Triggers dysfunctional cognitions

25
Q

Possible relapse prevention technique

A

Mindfulness

26
Q

What entails mindfulness

A
  • being aware of the situation without judgement

- accepting, letting go of struggle

27
Q

Study supporting mindfulness

A

mindfulness CBT raises likelihood of survival compared to placebo with clinical management and maintenance of antidepressants

28
Q

Cognitive Bias Modification

A
  • Training individuals to be more concrete and less overgeneralized in their thinking
    • leads to less rumination and better problem solving
    • significant reduction in depressive symptoms
  • Attentional training control: learn to selectively attend certain sounds and ignore others
    - Reduction in symptoms of DEP
