In recent years, there has been growing interest in examining role competence and the factors that can contribute to a sense of role competence among social workers. In the present study, we used the occupational competence model (OCM) as a basis for examining the contribution of the personal dimension (mastery, self-esteem, and secondary traumatization), environmental dimension (support systems),-and occupational dimension (exposure to the field of family violence) to the social worker's subjective sense of role competence. Participants in the study were 214 social workers employed at centers for prevention of family violence, at shelters for victims of violence against women, and at social service bureaus. The findings indicate that in the occupational dimension, the contribution of exposure to work in the field of family violence contributed significantly to two components of the participants' subjective sense of role competence: general sense of role competence and task knowledge/problem solving. In the personal dimension, the contribution of secondary traumatization and mastery to a sense of role competence was significant. In the environmental dimension (i.e., support systems), the specific contribution of managerial support to the participants' sense of role competence was significant. In light of these findings, practical recommendations for developing a sense of role competence among social workers are provided.
