Study hypothesis
To evaluate the cost-effectiveness, under service conditions, of case finding followed by computer-generated patient-specific clinical practice guidelines, compared with locally-agreed guidelines only, for the management of common mental disorders in primary care. The self-administered computerised assessment included
1. The Revised Clinical Interview Schedule (CIS-R), and
2. A social assessment covering sociodemographic characteristics, any current difficulties in housing, employment, finance and personal relationships, and the availability of social support.
In the course of this project, the previous version of the computer program entitled PROQSY (PROgrammable Questionnaire System) was upgraded so as to be compatible with Windows 95 and subsequent versions. Further modifications were also made. These included a method for detecting errors in the questionnaire files (or scripts), an integral randomisation command and new commands to provide more variety in the type face when generating the output for clinicians. The clinical practice guidelines were based on those developed by the World Health Organisation (WHO) for the management of psychiatric disorders in primary care (ICD10-PHC, Goldberg, 1994). These guidelines were discussed with the GPs in all 5 practices and they were given opportunities to alter any of the advice given in the guidelines. We also provided them with a list of local voluntary sector organisations and self-help groups and established whether the GPs regarded these as a useful organisations for patients. These groups were then incorporated in the guidelines.

Intervention
Cases of common mental disorder were identified by case-finding questionnaire and then randomly allocated within practices to
1. An intervention group, in which the GP was given the results of a detailed self-administered computerised psycho-social assessment, combined with patient-specific treatment recommendations, or
2. A control group, in which the GP was not given any additional information or advice, but who had access to a copy of locally agreed clinical practice guidelines.
Randomisation was performed by the computer which administered the questionnaires and generated the advice for the GP. The randomisation was therefore concealed from the research assistant and the subject.

Primary outcome measures
12-item General Health Questionnaire (GHQ12)
Outcome was assessed at 6 weeks and 6 months. The subjects were sent the questionnaires by post and were reminded by telephone if they did not respond.
Secondary outcome measures
1. Quality of life assessed with 6 questions
2. Satisfaction with treatment assessed with 1 question: If a friend were in need of similar help from a general practitioner would you recommend your GP to him/her?
3. Number of consultations in primary care assessed both by asking the subjects, and also by recording the number of consultations in the primary care notes of the subjects
4. In 2 of the practices we recorded the psychotropic medication prescriptions for all those in the trial.
