This study attempted to extend the concept of achievement motivation, as proposed by Weiner's attributional model, to social affiliative contexts. It was proposed that low social anxiety individuals behave like high achievement motivation individuals who make more self-attributions for success, but more external attributions for failure, whereas high social anxiety individuals take more personal responsibility for failure social outcomes, but make more external attributions when successful. Subjects were 243 undergraduate students, 143 females and 100 males. They completed the Leary Social Anxiety Scale, the Lefcourt Affiliation Locus of Control Scale, the Fenigstein Social Anxiety Scale, the Social Attribution Scale, and the Russell Causal Dimension Scale.
