Lewinsohn's behavioral measures of social skill: their stability and relationship to mood level and depression among college students.

Reports on investigations of the stability of eight of Lewinsohn's (1975) measures of social skill and their relationship to indices of depression and mood level in college students who are attending small informal discussion groups. Five of his measures showed no significant degree of stability across group sessions. The remaining measures, mainly indices of activity level, showed a significant though only moderate degree of generalizability. No significant differences in activity level were found between depressed and nondepressed Ss. However, several post-hoc analyses revealed that the variability of the Ss' mood and behavior across group sessions was associated significantly with their D30 scores. Depressed Ss were more variable in their mood and behavior. Implications of these results are discussed briefly.
