Self-efficacy as a mediator in bottom-up dissemination of a research-supported intervention for young, traumatized children and their families

Implementation literature has under-reported bottom-up dissemination attempts of research-supported interventions (RSI). This study examined factors associated with individual clinicians’ implementation of Child–Parent Psychotherapy (CPP), including CPP social network (SN), supervision, and self-efficacy. Seventy-seven (90%) CPP graduates completed a cross-sectional survey, including measures regarding social network, receiving supervision, and CPP self-efficacy. Self-efficacy was significantly associated with CPP implementation; CPP SN and supervision were not. Mediation models showed that self-efficacy significantly mediated between CPP SN and supervision, and the implementation variables. Findings illuminate the importance of supporting clinicians using a new RSI, particularly in bottom- up dissemination, in order to foster RSI self-efficacy.
