MMPI and EPPS Profiles of High and Low Verbal Interactors in Therapy Groups

The frequency of verbal interactions between patients in four open therapy groups was found to be to a statistically significant degree negatively correlated with scores on the L and K scales of the MMPI and the scale of Order on the EPPS, and positively correlated with the Ma scale on the MMPI and the scale of Aggtession on the EPPS. This was interpreted to mean that patients who on these psychometric tests are shown to be defensive are unlikely to interact with other group members as often as patients who score low on the trait of defensiveness. On the other hand, patients whose test results show them to be forceful, vigorous, aggressive, and candid are likely to interact with other group members more often than ere patients who score low on these personality traits. The findings were discussed in the light of previously reported similar investigations and with reference to their possible practical usefulness to group therapists.
