Introducing Semantic Cohesion Analysis

Abstract

This article introduces semantic cohesion-a nonreactive, atheoretical indicator of conversational involvement-to the study of group process. Conversational involvement is assumed to be necessary and common to all types of groups, but groups achieving more cohesive involvement are expected to be relatively more effective. Cohesive talk was observed over time and across four psychotherapy groups led by self-disclosing or nondisclosing therapists; clients'perceptions of the process and outcome were assessed on multiple indicators. Despite individual therapist differences, the nondisclosing groups showed significantly more cohesive interactions throughout (and especially in the early phase) therapy. No differences were observed in clients'perceptions of therapists or their attraction to the group. On all indicators clients showed appreciable gains, but the nondisclosinggroups were relatively more successful. Differences in how self-disclosing and nondisclosing leaders elicit group involvement are discussed and the utility of semantic cohesion analysis in future work on group process is considered.
