Effect of a structured educational intervention on explanatory models of relatives of patients with schizophrenia: randomised controlled trial.

Abstract

We examined the effect of a structured educational programme on explanatory models of illness among the relatives of people with schizophrenia, in a randomised controlled trial. Participants were assessed at baseline (n=100) and after 2 weeks (n=75) using a vignette from the Short Explanatory Model Interview. There was a reduction in non-biomedical causal explanatory models at follow-up among those who had completed the structured educational programme compared with the control group. There was no significant difference in non-biomedical treatment explanatory models between the two groups.
