Abstract
This outcome investigation compared the relative efficacy of two assertive training groups for self-report indices of assertiveness and anxiety. 36 female subjects were assigned to one of four experimental conditions: (a) 8-hr. assertive training, (b) 2-hr. assertive training, (c) 8-hr. no-treatment control, or (d) 2-hr. no-treatment control. Significant increases in assertiveness at posttreatment and 2-wk. follow-up were noted only for the 8-hr. treatment group. None of the groups showed significant reductions in trait or state anxiety levels. Treatment of the two control groups in 4- and 6-hr. assertive training programs produced data suggesting that increases in assertiveness relate to length of time in treatment. Implications of these findings for program development and future research are discussed.
