External evaluation of efficacy by means of an Adjective Check List scale for observers

Reports the development of an observational scale for efficacy developed from the Adjective Check List. The 42 items in the scale had interitem alpha coefficients ranging from .82 to .96 in 12 examinations, though interobserver correlations were lower, ranging from .36 to .54. In subsamples that included 236 males and 236 females, scores on the observational scale were positively related to various demographic and self-report indices of attainment, self-confidence, and personal resourcefulness.
