The goal of this study was to investigate the relationships among demographics variables (age, sex, and ethnicity), organizational culture, interpersonal self-efficacy, and perceived job performance of nonprofit human service workers. The 13 participating organizations provided services such as adoption assistance, adult daycare services, child care resource and referral help, children's daycare services, family counseling, children and youth mentoring, residential care for elderly, residential care for persons with disabilities, and substance abuse treatment programs. Only 607 full-time workers filled in the questionnaire. The response rate was 54%. Findings in the present study found that self-efficacy is a major predictor of performance. This study found that to perform more effectively at the interpersonal level, nonprofit human service workers require expertise,resources, organizational and supervisor support, self-efficacy and the opportunity to engage in interpersonal interactions on job-related matters. Furthermore, the empirical results of this study support the two categories of job performance: task and contextual performance, and individual differences among workers. Sex and ethnicity had a disordinal interaction on self-ratings of contextual job performance. The findings have implications for workers, managers, policymakers, and nonprofit researchers. Suggestions are also offered to improve areas such as management and communication practices, advocating, counseling, and mentoring skills, and collaborating, supporting, volunteering, and technical skills.
