"Use of self" is a central concept throughout social work history and theory, yet no unified definition and little empirical research exist. Thus, a qualitative exploration was required. Three focus groups (n = 10) were conducted with experienced BSW educators. Participants defined use of self in the context of their students' beginning social work practice. The findings suggest that use of self incorporates personal self qualities such as openness, self-reflectiveness, attunement to others, commitment, and emotional maturity, and results in professional capacities such as nurturing the social worker-client relationship, reflective practice, and practice wisdom. Use of self is the integration of theory and practice embodied in the social worker and enacted in the worker-client relationship.
