| The purpose of this study was to examine collective efficacy formation. I conceptually proposed and empirically tested a model in which interpersonal group trust mediates the impacts of the four main antecedents of efficacy belief (i.e., past performance, vicarious learning, social persuasion, and group affect) on collective efficacy. Data were collected from 102 ongoing intact manufacturing work groups (484 individuals) in China. Past performance, social persuasion, and group affect were found to have statistically significant relationships with collective efficacy. Interpersonal group trust fully or partially mediated their relationships with collective efficacy. Neither direct nor indirect relationship of vicarious learning with collective efficacy was found. Collective efficacy was positively related to group performance. The four antecedents and interpersonal group trust together accounted for about 46% of the variance in collective efficacy. |
