Hispanic ethnicity and social self-concept were positively associated with counseling self-efficacy when culture differences were present. Physical self-concept was positively associated with self-efficacy related to physical activity topics. Nutrition assessment skill was negatively associated with self-efficacy for working with non-English-speaking clients.Conclusions and ImplicationsDevelopment of MI skills and strategies to improve social and physical self-concept may increase WIC nutritionists' counseling self-efficacy, particularly when counseling clients from diverse backgrounds.
