Simplified use of the semantic differential to measure psychotherapy outcome.

To initially establish the validity and utility of a simplified use of the Semantic Differential to measure psychotherapy outcome, 14 clients were administered, before and after 15 sessions of individual psychotherapy, the Semantic Differential and a symptom checklist. As predicted, results indicated that change of clients' self-constructs in a positive direction was associated with symptom reduction. Implications for psychotherapy research are discussed.
