A sequence of action-oriented games and initiatives is provided in this guide for group therapy leaders who wish to employ activities to promote trust, problem solving, and cohesion among group members. Introductory material discusses the objectives of action-oriented therapy, the adaptation of traditionally outdoor activities to indoor settings, and the balance of activity time to processing time. Following the introduction, a history of adventure activities for groups is presented in outline form, highlighting the distinctive features of Outward Bound, New Games Foundation, Playfair, and Project Adventure--organizations that have pioneered in adventure education, creative play, and experiential learning. The third section gives directions for six warm-up games, six games for pairs, and seven activities for group problem solving. Following the activities are ten tips for leaders of processing/debriefing sessions. These include asking the group to evaluate the activity, discussing how group members felt as they were participating, and relating games and initiatives to issues facing the group. A seven-step approach to creative problem solving gives directions for brainstorming, identifying and evaluating alternative problem solutions, and developing a sequential plan for implementing a solution. A bibliography of 16 references is included. (JHZ)
