This manual was devised to help supervisors, counselors, trainees, and other educators to better understand and improve counselor/client interview behavior through utilization of the Counselor Client Behavior Analysis System (CCBA). The CCBA is an interaction training and/or research schema designed to provide a formalized feedback system on the types (and their efficacy) of interactions between a counselor and his client. A general picture of what is being studied is provided in the CCBA Instrument, which lists: (1) specific types of counseling interactions; (2) their corresponding subroles (i.e., the intention of the counselor and/or client during these interactions); and (3) observational guidelines for judging whether a specific interaction assists or impedes the counselor/client relationship. The manual comes complete with comprehensive definitions, a coding sheet designed specifically to accompany the CCBA System for recording observations of the counselor/client interactions, and ample instructions for implementing it. Also included is a section on various approaches to data treatment utilizing the coding sheet information or employing a specifically designed CCBA matrix. The emphasis throughout is placed on making the manual a practical guide for utilizing the CCBA System in studying counselor/client interactions. (TL)
