This article argues for more research and audit by group psychotherapists in order to inform clinical practice and to influence resource allocation. Problems encountered in research are described. The need for careful planning is emphasized. The choice of outcome measures is discussed and also the choice of research protocol by symptom questionnaire or by change in use of psychiatric services. An account is given of the CORE outcome measure. Reasons for missing data are given and ways are suggested of analysing incomplete data that can provide useful information, using as an example figures from our outcome study on a slow-open group of 94 patients.
