Module 3: Psychological Problems Flashcards
Name symptoms of unipolar depression
- Lowering of mood, tiredness unrelieved by rest, lack of motivation
- Poor sleep, poor/increased appetite, lack of enjoyment in previously enjoyed activities, low self-esteem, feelings of guilt, suicidal thoughts
What is required for a unipolar depression diagnosis?
- One main symptom present most time/days for two weeks
- One other symptom present at some point
How are the different severities of unipolar depression identitified/classified?
- Mild: 4 symptoms
- Moderate: 5-6 symptoms
- Severe: 7+ symptoms and general feelings of worthlessness
Why is depression more commonly diagnosed now than in the past?
- Reduction of stigma
- Increasing knowledge of mental health
- Modern life more stressful and so more likely to cause depression
What are the effects of depression on an individual?
Increased risk of suicide (suggested 10-15% of people with severe depression commit suicide)
What are the effects of depression on society?
- Time missed from work: behind on work –> guilt –> worsens depression, company must cover workload
- Cost of treatment: antidepressants expensive, not enough trained therapists
What studies give evidence for the genetic explanation of depression?
- Craig Hyde et al. (2016), 17 gene variations linked to depression, more likely to develop if family member has it
- Peter McGuffin et al. (1996), identical twins more likely to be depressed if the other one is than non-identical twins
What is the diathesis-stress model of depression?
Some are genetically predisposed to develop depression but only develop it if exposed to stress that activates the gene
What are the strengths of the genetic explanation of depression?
- Lessens stigma (cannot be blamed for depression)
- Research evidence
What are the weaknesses of the genetic explanation of depression?
- Deterministic (assumes people have no free will over being depressed)
- May be reductionist (fails to take life events into account)
Describe Aaron Beck’s cognitive explanation of depression
Cognitive triad: negative view of world –> negative view of self –> negative view of future –> (repeat)
- Example of cognitive bias (negative self-schema)
- Leads to magnification (negative exaggeration)
Describe Albert Ellis’ cognitive explanation of depression
ABC Model: Activating event (stress) –> Beliefs (either rational or irrational) –> Consequences (rational belief (true) –> no depression, irrational belief (untrue) –> depression)
What are the strengths of the cognitive explanation of depression?
- Acknowledges life events, takes nature/nurture into account
- Practical applications (CBT)
What are the weaknesses of the cognitive explanation of depression?
- Can’t tell if negative thoughts a cause or symptom
- Post-natal depression more likely caused by hormones (unclear event)
What are the aims of cognitive behavioural therapy?
- Help change the way the patient thinks
- Help change the way they act to improve symptoms
What is the process of cognitive behavioural therapy?
- Patient discusses symptoms (thoughts, feelings, behaviours)
- ‘Homework’, change ways of thinking & write down feelings
What are the strengths of cognitive behavioural therapy?
- Evidence: Beltman et al. (2010), CBT patients improved more than non-CBT
- Longer lasting treatment (skills permanent, drugs temporary)
- Gives patients self-determination
What are the weaknesses of cognitive behavioural therapy?
- Relies on patients recognising symptoms and wanting to change (lack of motivation a main symptom)
- Ethical issue: patient told their ways of thinking are ‘wrong’, therapist may abuse power
What are the four types of antidepressants?
- SSRI, block re-uptake of serotonin, make is available for longer
- SNRI, block re-uptake of serotonin and noradrenaline
- MAOI, prevent enzyme monoamine oxidase from breaking down serotonin and noradrenaline
- TCA, prevent reabsorption of serotonin and noradrenaline
What are the strengths of drug therapy as a treatment for depression?
- Improves symptoms so allows patients to access other treatments (CBT)
- Evidence: Royal College of Psychiatrists study
What are the weakenesses of drug therapy as a treatment for depression?
- Side effects (diabetes, insomnia, suicidal feelings)
- Helps symptoms, not cause (relapse upon treatment stopping)
What are the symptoms of addiction (dependence disorder)?
- Feeling of needing to take the substance
- Stopping very difficult
- Physical withdrawal symptoms (shaking, sweating, vomiting)
- Tolerance to substance
