Abstract

Two-stage screening for minor psychiatric morbidity was carried out with a consecutive sample of 256 patients aged 15–69 consulting an experienced GP in a semirural setting over a seven-week period. Patients completed a short GHQ, and the GP made a standardised assessment of the reason for consultation and the degree of psychological disorder. A 40% random subsample were evaluated using PROQSY, a newly developed computerised psychiatric assessment based on the CIS. PROQSY is acceptable to patients in general practice, and yields an estimate of the prevalence of minor psychiatric morbidity (33%), and validity indices for the 12-item, 28-item, and 30-item GHQs, comparable with those found in similar studies, when the CIS has been administered by an interviewer. PROQSY may be recommended as a research tool, providing a criterion measure of minor psychiatric morbidity in general practice, where it may reduce time and manpower, and eliminate interviewer bias.
