This paper, presented at the April 1976 meeting of the Eastern Psychological Association, reports part of an ongoing study of psychiatric interviews at Hahnemann Medical College and Hospital in Philadelphia. Faculty from the Department of Mental Health Sciences are videotaped in initial evaluative interviews with clients who volunteer from the psychiatric facilities of Hahnemann. Client and therapist fill out questionnaires on their experiences of the sessions, and clients are given psychological tests. In future stages of the project, these will be correlated with movement assessments. The present paper deals with observer and repeat reliability on parts of the extensive inventory of patients' and therapists' body patterns. The Individual Movement Patterns Inventory used deals with individual style assessment, pathological features of movement, sex-role stereotypic nonverbal behaviors, interpersonal variables, and items believed to relate to cultural differences. Initial results suggest that individuals have consistent movement patterns over time, and those can be reliably assessed by trained observers. Therapist expressive movement patterns are focussed on, with descriptive examples of individual differences presented. The paper concludes with therapist role-specific nonverbal patterns, preliminary observations of patterns of eye contact, facial expression, gesturing and interacting nonverbally which appear related to the therapy context.
