Abstract

Background

Explanatory models of illness may differ between ethnic groups and influence treatment satisfaction and compliance.

Aims

To compare explanatory models among people with schizophrenia from four cultural backgrounds and explore their relationship with clinical and psychological characteristics.

Method

Explanatory models, insight, treatment compliance, health locus of control, quality of life, treatment satisfaction, therapeutic relationships and symptomatology were assessed in UK Whites and Bangladeshis, African-Caribbeans and West Africans.

Results

When biological and supernatural causes of illness were compared, Whites cited biological causes more frequently than the three non-White groups, who cited supernatural causes more frequently. When biological and social causes were compared, Whites cited biological causes more frequently than African-Caribbeans and Bangladeshis, who cited social causes more frequently. A biological explanatory model was related to enhanced treatment satisfaction and therapeutic relationships but not treatment compliance.

Conclusions

Explanatory models of illness contribute to patient satisfaction with treatment and relationships with clinicians.
