Interventions Into Group Process: An Approach to Improving the Effectiveness of Groups*

ABSTRACT Some new directions for research on group effectiveness are proposed. These include: (a) explicit recognition of group interaction process as the moderator of input‐output relationships in groups; (b) research which focuses on the functions of group interaction in influencing group performance; and (c) use of experimental interventions which create new, non‐typical patterns of interpersonal behavior in groups as an approach to studying group effectiveness. The results of two studies based on these proposals are summarized. One study examines the effectiveness of implicit vs. explicit discussion of group task “strategies”; the other addresses the effects of implicit (“traditional”) vs. explicit (“adaptive”) approaches to the maintenance of internal social relationships in work groups. Implications of the research are drawn both for future research on group effectiveness, and for the design of interventions aimed at improving the performance of on‐going groups in organizations.
