Professional psychologists are increasingly encouraged to utilize evidence-based treatments (EBTs), and therefore have a need to participate and provide the most efficient training methods for these treatments. Multicomponent trainings, which commonly include ongoing support, are more effective than brief methods such as 1-day workshops or reading treatment manuals. The present study examined the effectiveness of 1 form of ongoing support, consultation, as part of a multicomponent training protocol. Thirty-two community-based clinicians were trained in Parent-Child Interaction Therapy (PCIT) as part of a statewide implementation effort, and data were collected on clinician and implementation outcomes at pre-, mid-, and posttraining. Simple and multiple linear regression analyses were conducted to predict posttraining knowledge, skill, acceptability, and feasibility, as well as to examine clinician variables that might moderate these relations. Greater consultation call attendance significantly predicted higher posttraining skill; however, this association was qualified by a significant interaction with PCIT caseload. Implications for training guidelines are discussed.
