Abstract
The study of the psychotherapeutic process presents special problems to clinicians and clinician investigators. In the absence of supportive, working relationships between the therapist, patient and investigator, important data about therapeutic transactions cannot be obtained. In addition, we are lacking methodologies for isolating the significant therapeutic factors which explain variations in the outcome of psychotherapy. These problems need to be jointly addressed by clinicians and investigators if we are to advance the theory and practice of psychotherapy.
