Multilevel structural validation of Leary's interpersonal diagnosis system.

Interpersonal Check List (ICL) ratings and TAT protocols were obtained from 150 university sorority women, constituting 14 groups who rated themselves, rated 5 others within their group, and were rated by 5 others within their group. Independent factor analyses of self-rating (Level II ICL), public impact (Level I ICL), and TAT (Level III) octant scores were rotated to maximum similarity. Three roughly orthogonal factors, 2 bipolar and 1 monopolar, were extracted at each level. Factor loading plots of Factors I and II (the bipolar factors) yielded a circular array roughly conforming to T. Leary's (1957) circumplex model at Level I ICL, Level II ICL, and the "best-fit" matrix, but not at Level III TAT. Factors I, II, and III were congruent across Levels I and II ICL, whereas only Factors I and II matched all 3 levels. Support for the Leary model was fairly strong for Levels I and II ICL and modest for Level III TAT. Cross-level octant correlations were significant but modest across Levels I and II ICL. All such correlations involving Level III TAT were insignificant. Although generally similar dimensions were measured at different levels, octant scores were not necessarily interchangeable across levels.
