A session-level analysis examines the relationship between intimate behaviors of an individual group member and of the other group members in a session, and individual group member attendance in the following session. Specifically, the model proposed by Kenny, Mannetti, Pierro, Livi, and Kashy (2002) for analyzing individual and group effects in small groups is used to examine session attendance in 575 group sessions for 30 group members in 5 interpersonal growth groups. Either being the member who enacted the most or least intimate behaviors in a session, or having a relatively lower level of intimate behaviors by the other group members in a session, decreases the likelihood that a group member would attend the following group session. These findings are interpreted in terms of Yalom and Leszcz’s (2005) ideas about being a group outlier and the importance of group context. Implications for research and practice are discussed.
