Summary

A new computerised tool, PROQSY, effectively screens for minor psychiatric morbidity in general practice, showing a 33% prevalence. This method is reliable and reduces bias in psychiatric assessments.

Area of Science:

  • Psychiatry
  • General Practice
  • Health Services Research

Background:

  • Minor psychiatric morbidity is prevalent in primary care settings.
  • Accurate screening tools are essential for identifying and managing mental health conditions in general practice.
  • Existing screening methods may have limitations in terms of time, manpower, and potential for bias.

Purpose of the Study:

  • To evaluate the acceptability and utility of PROQSY, a novel computerised psychiatric assessment tool.
  • To estimate the prevalence of minor psychiatric morbidity in a general practice population.
  • To assess the validity of different versions of the General Health Questionnaire (GHQ) using PROQSY as a criterion measure.

Main Methods:

  • A two-stage screening process was implemented with 256 patients (aged 15-69) consulting a general practitioner.

  • Patients completed a short General Health Questionnaire (GHQ).
  • A 40% subsample underwent evaluation using PROQSY, a computerised assessment based on the Clinical Interview Schedule (CIS).

    • Main Results:

    • PROQSY was found to be acceptable to patients in a general practice setting.
    • The estimated prevalence of minor psychiatric morbidity was 33%.
    • Validity indices for 12-, 28-, and 30-item GHQs were comparable to previous studies when using PROQSY as the criterion.

    Conclusions:

    • PROQSY is a recommended research tool for measuring minor psychiatric morbidity in general practice.
    • This computerised approach can potentially reduce time, manpower, and interviewer bias in psychiatric assessments.
    • PROQSY provides a reliable criterion measure for validating screening instruments in primary care settings.
