Several effects of client-centered therapy were predicted on the basis of a short intake-interview divided into two parts: an exploration-phase and a quasi-therapy-phase. Elements of the international behavior and elements of the intrapersonal exploration of the client were rated by neutral observers and served as predictor variables as well as ratings of the experiences in the two interview situations by the client himself. Our population were 29 out-patients of a psychiatric clinic. We could demonstrate, that on the basis of an 45-minutes intake-interview it is possible to make a rather good prediction of the therapy outcome -- measured by several clinically relevant personality scales -- though therapists and interviewer were not identical and though there was a waiting period of several weeks between the interview and the start of therapy and though the therapists were rather unexperienced.
