  • Genetic Explanation
    • Strong relationships between genetic similarity of family members and likelihood of both being diagnosed with depression
    • Biological Etiology of Depression
      • Biological Determinism
      • Reductionism v holism
      • Bidirectional ambiguity
        • Capsi et al (2003) People who had inherited one or more short versions of the allele demonstrated more symptoms of depression and suicidal ideation in response to stressful life events.
          • Diathesis-stress
            • Kendler et al (1995) interaction between stressful life events and genetic predisposition
