Predictive Validity of Addiction Treatment Clinicians' Post-Training Contingency Management Skills for Subsequent Clinical Outcomes.

In the context of a contingency management (CM) implementation/effectiveness hybrid trial, the post-training implementation domains of direct-care clinicians (N=19) were examined in relation to a targeted clinical outcome of subsequently CM-exposed clients. Clinicians' CM skillfulness, a behavioral measure of their capability to skillfully deliver the intended CM intervention, was found to be a robust and specific predictor of their subsequent client outcomes. Analyses also revealed CM skillfulness to: (1) fully mediate an association between a general therapeutic effectiveness and client outcome, (2) partially mediate an association of in-training exposure to CM and client outcome, and (3) be composed of six component clinical practice behaviors that each contributed meaningfully to this behavior fidelity index. Study findings offer preliminary evidence of the predictive validity of post-training CM skillfulness for subsequent client outcomes, and inform suggestions for the design and delivery of skills-focused CM training curricula for the addiction treatment workforce.
