A self-report inventory was compared with a situational test as a predictor of the verbal behavior of individual members of small interpersonal skills training groups. As hypothesized, the situational test was a better predictor than was the self-report inventory. A powerful social conformity effect may have operated in both the situational test and the criterion groups, perhaps obscuring individual differences in preferred styles of interaction, which the self-report inventory seeks to measure.
