The process of assertive behavior change of college women who received assertion training (AT) and cognitive restructuring was examined to assess the relative effects of different durations of exposure to cognitive restructuring. Undergraduate and graduate women students (N=27) at a state university volunteered and were screened for AT groups. Single-subject methodology was utilized to plot the process of change in subjects' assertive behavior and situational discomfort when asserting themselves. Idiosyncratic individual patterns of situational discomfort and behavior changes suggest the need for research designs which focus on individual progress records rather than global group improvement.
