In this multipaper session we introduced how the use of coaching log could help document dosage for future impact studies, and help formalize and manualize intervention components. Presentation Abstract: To attribute change to a particular intervention, it is necessary to be sure that the intervention was conducted as intended. In the case of a new intervention, elements that constitute the intervention – for example, the content, process, and structure - must be documented to permit replication, program improvement, identification of core and flexible components, and scaling up with fidelity. Combined training/coaching interventions have been increasingly emphasized as an avenue for behavior change compared to training alone. However, coaching often relies on the judgment of the coach. This presentation describes how an online coaching log and coach interviews were used to identify the intervention content, process, and structure of an organizational intervention to develop youth-adult partnerships. The study demonstrates how this process helped: a) identify the core and flexible components of an intervention; b) examine the implementation of the intervention; and c) permit assessment of dosage as a predictor of change.#CoachingLog #HowTo #MSUUOE #EvaluationUse #YouthFocusedEvaluation #2012Conference
