L3 - Depression Flashcards
What is depression?
- Sadness, discouragement, pessimism, hopelessness
- Sometimes adaptive e.g low mood helps to disengage individuals from unproductive efforts
When does depression become clinically significant?
- Unusually severe or prolonged
- Results in significant impairment at the personal, relational and professional levels
What Is major depressive disorder?
5+ symptoms have been present during the same 2-week period and represent a change from previous functioning
What are the symptoms of MDD?
- Depressed mood most of the day
- Diminished interest/pleasure
- Significant weight loss/gain, appetite increase/decrease
- Insomnia/hypersomnia
- Psychomotor agitation or retardation
- Fatigue/loss of energy
- Feeling of worthlessness
- Diminished ability to think
- Recurrent thoughts of death
What are features of depressive disorders?
- High comorbidity with anxiety/stress
- More prevalent in females than males
- Variety of symptoms: hard to diagnose
- High likelihood of recurrence - increases with number of prior episodes and presence of comorbid disorders
What are the genetic causes? (Evidence)
Prevalence of mood disorders 2/3x higher among blood relatives
What are environmental causes?
- Stressful life events: 70% of people with a first onset of depression
- Chronic stress
- Social media
What is an example of gene-environment interplay?
- Diathesis stress model
- Neurotic individuals have negative appraisal of events and are more likely to experience stressful life events
What is the psychodynamic perspective?
- Anger turned inwards
- Response to imagined/symbolic loss
- Similarities between depression and grief
What is the behavioural perspective?
- Lack of positive reinforcement
- Lack of the reinforcement capacity of previously reinforcing stimulus
- Increase in negative reinforcement
- No causal link
What is the Behavioural Activation Treatment?
- Scheduling daily activities, mastery and pleasure tasks, exploring alternative behaviours to reach goals
- Goals are to increase levels of positive reinforcement and reduce avoidance and withdrawal
What is the cognitive perspective?
- Cognitive Depressive Triad: About negative appraisals about the self, the world, the future
- Depressogenic schemas = rigid, extreme and counterproductive way of thinking
- Select, code and evaluate stimuli
- Significance of experiences
- Accompanied by memory biases
What is Beck’s Cognitive Theory? (graph)
- Early experience = dysfunctional attitudes/beliefs = depressogenic schemas = cognitive triad
- Depressogenic schemas = severe/mild stressful events = activation of schemas = cognitive distortions = conditional beliefs = NATs (negative automatic thoughts)
- NATs = depressive symptoms = Behavioural, motivation, affective, cognitive, somatic
What is Beck’s Cognitive Theory?
- Depressed people have reduced positivity attribution bias
- Cognitive vulnerability predicts onset and recurrence
- Diathesis Stress = stressful life events moderate association between cognitive vulnerability and depression
What is Cognitive Behavioural Therapy?
- Our interpretation of events determine our emotional states
- Distorted or irrational thinking patterns lead to emotional problems and maladaptive behaviour
- Result from inaccurate or biased processing of information in the world = cognitive distortions
- e.g NATs (im being boring) = beliefs/distortions (if people know me, they’ll know im useless) = schemas (im unloveable)
