Verbal and Nonverbal Behavior in Therapy Session: Effects of Drug
Time Frame: videotapes of session were reviewed and scored 1-3 months after the patient completes the study
|
Videotapes of 2 therapy session (PBO/OT) were reviewed by blinded raters to determine differences in two treatments.
There were nine aspects analyzed using the Ethological Coding System for Interviews: eye contact, affiliation, submission, prosocial, flight, assertion, displacement, relaxation, and gesture.
