In a study using 73 females and 30 male undergraduates, information on the basic dimensions of Millon's eight personality styles was obtained from correlations of the Millon Behavioral Health Inventory with Rotter's I-E scale and Byrne's R-S scale. Hypotheses predicting a significant relationship between the active-passive and repression-sensitization were generally supported. Predictions of a significant relationship between the dependent-indepenent dimension and generalized expectancy of locus of control were not supported. Implications of these findings for the efficacy of Millon's system are discussed, along with future research possibilities.

The Purpose of this study was to investigate the relationship of the repression-sensitization dimension and leisure preferences, specifically threatening versus nonthreatening physical activity and television program preferences. The hypotheses were that sensitizers would prefer threatening (violent) television programs and threatening (competitive) physical activities to a significantly greater degree than repressors. Sixty college undergraduates were designated repressors, sensitizers, or middle group by their scores on Byrne's Repression-Sensitization Scale. Preference sheets determined subjects' preferences for threatening and nonthreatening television programs and physical activities. Simple analyses of variance revealed no significant differences in repressors', sensitizers', or middle group's preferences for threatening television programs or physical activities, and thus the hypotheses were rejected. Non-significant tendencies in the data, in hypothesized directions, suggest further research.
