CONSTRUCT VALIDITY FOR EVALUATION OF THERAPY OUTCOMES

Evaluation is a matter of judging conformity to certain values and the judgment of how healthy or diseased a person is. The 1st step in doing outcome evaluation studies of psychotherapy is to choose a reference group or public and find out what its relevant values are. Patients, clients, sponsors, and therapists constitute 4 such publics with somewhat different values. Probable value criteria for these publics are proposed and the problems of defining and collecting valid data for these criteria are discussed.
