Designed to serve training oriented professionals, therapy oriented practitioners, and practicing managers, this book presents insights into the change process, along with problems contained in efforts to evaluate this process in management training and in therapy. First, the four essential strategic problems of evaluation are set forth: setting criteria; measurement and control; reducing the contamination of participants. A detailed example of therapy evaluation is drawn from the work of Alcoholics Anonymous, with attention to such elements as personality profiles, attendance, results of overall treatment, and reentry into society. Next comes a case study of a conference leadership discussion program that stressed supervisory decision making. Both studies have employed rigorous evaluation designs (including Solomon's Four-Way Design) which lay bare the underlying change processes. The focus then shifts to the positive values of evaluation in terms of organizational and individual change. Finally, practical implications and suggestions are offered. An index and 36 references are included. (Author/LY)
