Treatment fidelity, including adherence and competence, is assessed during the implementation of evidence-based treatments to ensure that care delivered as intended. Although fidelity monitoring often resource-intensive, a relationship between treatment outcomes has not been clearly demonstrated. Associations observer-rated clinician family were investigated in longitudinal sample clinicians (n = 18) parent-child dyads 39) following statewide Parent-Child Interaction Therapy. Results indicated neither nor coaching competence predicted changes outcomes. Explanations for these findings, study limitations, directions future research are discussed.
