This mixed-methods research examined the translation of a family nursing conversation intervention to the multidisciplinary treatment of patients experiencing chronic noncancer pain. The intervention required educating nurses who offered family nursing interventions to these families. The research uncovered barriers and facilitators influencing the nurses' perceived self-efficacy related to the process of incorporating family nursing conversations in their nursing care. A qualitative, descriptive, longitudinal design with three focus group interviews was implemented. A template analysis, using themes based on Bandura's self-efficacy theory, illuminated a process initially predominated by barriers. Learning how to offer family nursing conversations was initially overwhelming for nurses because they were concerned about harming the family. Over time, the nurses came to understand the usefulness of the therapeutic conversation with families. Significant facilitators were the project manager's role, a strong nursing community, and the positive influence of the family intervention on the nurses' professional identity.
