Fourteen behavior therapy patients were interviewed to determine if phenomena regularly observed in psychodynamic psychotherapies had occurred in their behavior therapies as well. Interview data were analyzed both statistically and clinically. Ratings by patients, their therapists, and the Es indicated that the prevalence of behavior modification techniques in the therapy was not significantly related to outcome, whereas a variety of the patients' personal feelings about their therapists were. Impressionistic analysis of the interviews also suggested that the important elements of these therapies were interpersonal ones, much as has been demonstrated in psychodynamic psychotherapy. The behavior modification techniques themselves seem to have added little to the therapies, and in some instances may even have facilitated continued defensive avoidance of problems.A careful reading of the proliferating behavior therapy literature reveals that the model of therapist and patient, rationally cooperating to the fullest in a straightforward, scientific enterprise, is met with only in theory and rarely, if ever, in actual practice. The observations of Klein, Dittmann, Parloff, and Gill (1969), for example, suggest that there is much more to the conduct of behavior therapy-at least as it is practiced by Wolpe and Lazarus--than is generally believed. If one pays close attention to patients' words and actions, as they are quoted or described in behavior therapy case reports, one is struck by the variety and intensity of feelings these treatments elicit, and the substantial portion of those feelings which is irrational, unreasonable, and even theoretically iconoclastic-precisely the same situation as exists in traditional, psychodynamic psychotherapy. Some of the authors who describe feelings which are similar to those arising in verbal psychotherapy include the following: Bond and Hutchison (1960), Carter (1968), Cooper, Gelder, and
