Abstract
This article emphasizes similarities between Berne's concept of group imago adjustment and the stages of group development as conceptualized by Tuckman (1965) and Lacoursiere (1980), highlighting the most relevant tasks of group leaders at different phases of a group's maturation. Feedback from practitioners and trainees is used to identify useful group leader behaviors at different stages. The article focuses on how developmental phenomena related to the group as a whole can be understood and used as an adjunct to individual psychotherapy in the group, not as a substitute for it. Particular factors in the blending of individual and group psychotherapy are also discussed.
