Controlled trials in the evaluation of counselling in general practice.

In this paper the difficulties of conducting a controlled evaluation of counselling (brief psychotherapy) in general practice are discussed. Results of a pilot study indicate that patients referred by family doctors to counsellors are often seriously emotionally distressed and recovery is slow. Counsellors come from different backgrounds and use a variety of therapies. Although the results show that controlled research is feasible, in a definitive trial patients should be randomized in a stratified manner, according to severity, by the researcher after initial assessments have been made. Counsellors should have a recognized accreditation and preferably be employed for the trial to ensure uniformity of approach and avoid long waiting lists. Blind assessments of outcome are desirable but are not always feasible and reliance on patient self-report is important. Within the limitations of current knowledge, only controlled evaluations will provide a greater understanding of the efficacy of counselling in general practice.
