Assertion training: The effectiveness of a comprehensive cognitive-behavioral treatment package with professional nurses

Abstract

The purpose of the study was to evaluate the effectiveness of a comprehensive cognitive-behavioral treatment package with a professional population of registered nurses using multiple self-report and role-play measures. Twenty-six self-referred registered nurses were randomly assigned to either a Treatment or Control group. The treatment package consisted of five weekly 2-hr sessions of group assertion training using the cognitive-behavioral model of Lange and Jakubowski. The Assertiveness Self-statement Test, the Rathus Assertiveness Schedule, the Adult Self-expression Scale, two Likert scales and role-play were used to evaluate changes over time. The results indicated: (1) the nurses in both groups at Pretreatment were clearly subassertive; (2) by Posttraining the Treatment-group members increased significantly their assertiveness as indicated on the self-report tests; (3) Treatment-group members had successfully maintained their improved assertiveness by the 2-month Follow-up; (4) the role-play ratings paralleled and supported the self-report results, but not at significant levels; (5) there was strong empirical support for the social validity of the treatment package; and (6) there was a high degree of treatment credibility for the cognitive-behavioral Assertion-training group. Overall, the results indicate clear support for the effectiveness of a broad-based cognitive-behavioral treatment package for treating subassertive behavior in a professional population of registered nurses.
