Integrating Realist Evaluation Strategies to Achieve 100% Evaluation of all Education,Social Work, Health, Youth Justice and Other Human Services: Example of Chautauqua County, NY and Moray Council, Scotland. Abstract: This demonstration will illustrate how realist evaluation strategies can be applied in the evaluation of 100% natural samples in schools, health, youth justice and other human service agencies for youth and families. These agencies routinely collect data that is typically not used for evaluation purposes. This demonstration will include new data analysis tools drawn from both the efficacy and epidemiology traditions to investigate patterns in this data in relation to outcomes, interventions and the contexts of practice. For example, binary logistic regression can be used repeatedly with whole school databases at every marking period to investigate the effectiveness of school-based interventions and their impact on school outcomes. The demonstration will include practice examples drawn from the SAMHSA funded System of Care that has enabled a 100% evaluation of over 40 agencies in Chautauqua County, New York State; and education, social work and youth justice services in Moray Council, Scotland.#SocialWork #CrimeandJustice #Alcohol,DrugAbuse,andMentalHealth #HumanServicesEvaluation #2011Conference #QuantitativeMethods-TheoryandDesign
