Interactionist approach + SZ

• Interactionalist approach-

  • Turkington et al- Biological + psychological explanations + therapies from both biological + psychological aspects
  • Old diathesis stress model- Meehl- diathesis= genetics (candidate gene) stress= environment (trauma)
  • New diathesis stress model- Ingram + Luxton - psychological trauma = diathesis is the trauma
  • Rispke- 108 genes - not 1 SZ gene
  • Read - child abuse = Hypothalamic-pituitary-adrenal system overactive = vulnerability to external stress
  • Huston- anything can be a stress trigger
• Interactionalist approach to SZ

  Evaluations-

  CPS- Tarrier - 315 P’s - medication + CBT or medication + counselling or (control) medication = better symptom decrease with combinations

  CPW- Jarvis - logical error of treatment-causation fallacy
• Interactionalist approach to SZ

  Evaluations-

  S- Tienari (2004)- 19,000 Finnish kids W/ SZ mothers adopted = high risk, compared to a control adopted W/O SZ= low risk - raised W/ hostility, criticism + no empathy = SZ only in high risk group - both impact

  W- original diathesis-stress model is over-simplified as it only states 1 schizogene without external factors - Houston- childhood sexual abuse = vulnerability + cannabis usage = trigger
