title: How should we measure outcome in psychotherapy?
abstract: The problem of assessing outcome in psychotherapy is considered by examining the experiment conducted by Bloch et al (1977). The experimental design and statistical considerations in investigating psychotherapy outcome are briefly examined. Tt is argued that attention should be directed towards assessing the severity of patients' problems rather than improvement after treatment.
