This study compared the relative effectiveness of two communication-skills training models: Ivey's Microcounseling Paradigm and Carkhuff's Systematic Human Relations Training Model. After 107 educational psychology students volunteered to participate in the group that fit their schedules, treatments were randomly assigned. Pretesting and posttesting of all subjects was conducted by administering the Index of Communication; responses scored on the scale for Gross Ratings of Facilitative Interpersonal Functioning yielded a function level for each subject before and after training. An analysis of covariance, evaluating the difference between groups with regard to levels of functioning, found significant differences between the two training models and between the experimental groups and the control group.
