Arjan has recently been diagnosed with schizophrenia. He has a biological uncle with the disorder. Arjan's symptoms first appeared shortly after he began using cannabis heavily while preparing for highly competitive university entrance exams. His clinical team is deciding whether to treat him with antipsychotic medication alone or to use a combination of antipsychotics and cognitive behavioural therapy (CBT).
Explain how the interactionist approach (including the diathesis-stress model) can account for Arjan’s diagnosis, and discuss the clinical value of using a combined treatment plan rather than drug therapy alone.
