Critically discuss - Criticism for whatever sources you use, but also pro and con for question topic
- Critically discuss the genetic theory for depression
- Critically discuss the social impact on depression
Diagnosis
Collishaw (2015) - Clinical diagnosis and treatment of child and adolescent psychiatric disorders increased over recent decades.
McElroy - Average number of symptoms reported higher in those born at the turn of the millennium, compared with those born in the 1990s, 1970s, and 1950s
Genetics / Heritability
Wray (2012) - Traditionally, heritabilities have been estimated from families' info from specific hospital registers, but finding sufficient numbers of families can be difficult.
Flint (2014) - “Despite convincing evidence for a genetic contribution to disease susceptibility, there has been a dearth of substantive molecular genetic findings.”
Caspi et al. (2013) - Serotonin transporter gene (5HTT) + Polymorphism (two short alleles). The specific combination of this and environmental stressors found to predict depression.
Researchers found that:
- 7.4% of total disease burden in 2010 attributed to mental health problems
- Depressive disorders accounted for 40.5% of this (approximately 3% of all burden)
- Genome-wide association studies – largely failed to identify specific genes associated with depression
Neurological
Pizzagalli et al. (2014) - Anhedonia has emerged as one of the most promising endophenotypes (hereditary bio-marker) of depression. Pizzagalli et al. summarised animal data indicating that "stress negatively affects mesocorticolimbic dopaminergic pathways critically implicated in incentive motivation and reinforcement learning."
Keren et al. (2018):
- Meta-analysis of 38 fMRI and 12 EEG studies.
- Consistent neural aberrations during reward processing in depression
- Blunted neural response to reward, may be more pronounced in under 18's.
Social
Cromby (2013) - All experiences require biology, but it's reductionist to reduce experiences to JUST biology.
Mandelli et al. (2015) - Meta-analysis 26 studies found emotional abuse showed the strongest association with depression. Other associations found were neglect, sexual abuse, domestic violence, and physical abuse.
McElroy - Those in lower SES classes (i.e. those with less income, education etc.) at greater risk of mental distress, but only in more recent generations.
Gender
Salk et al. (2017) - Women are twice as likely as men to meet the criteria for depression. Possible factors:
- Biological (e.g. hormones – findings mixed)
- Social
- Girls more likely to be abused
- Women more likely to be exposed to chronic stress (e.g. caregiving)
- Women tend to provide more social support to others facing stress; dubbed the ‘cost of caring’
- Social roles – may intensify self-critical attitudes about appearance
Treatment
Klerman et al. (1984) - Interpersonal psychotherapy: identifying key interpersonal problems, make decisions/develop strategies to solve these issues.
Jackobsen et al. (2017) - Several meta-analytic reviews find that SSRIs are an effective method of treatment for depression.
E Karyotaki (2016) - Combined therapy did produce better maintenance of recovery compared to pharmacotherapy alone at 6-months and 12-months+.
