Treatment integrity, in its broadest sense, is the extent to which an intervention is implemented as intended. Over the past 3 decades, understanding of treatment integrity has greatly evolved. This book summarizes the current state of our knowledge of treatment integrity on such topics as * how it fits into the larger contexts of evidence-based practice and implementation science * its relation to ethics and the law * conceptual models, assessment, promotion, and application * conceptual models of treatment integrity in the fields of medicine, prevention science, and health psychology * assessment of treatment integrity itself * how a conceptual model can inform the development of a comprehensive treatment integrity assessment system * its use in practice and research in education and psychology Authoritative and up to date, this volume is a unique resource for all professionals supervising, providing, or evaluating intervention services, including researchers and practitioners in clinical, counseling, and school psychology; child and adolescent psychiatry; social work; communication disorders; special and general education; program evaluation; and educational leadership.

Evidence-based interventions benefit learners only when they are implemented fully. Yet many educators struggle with successful implementation. This unique book gives practitioners a research-based framework for working with PreK-12 educators to support the effective delivery of academic, behavioral, and social-emotional interventions. Step-by-step procedures are presented for assessing existing implementation efforts and using a menu of support strategies to promote intervention fidelity. In a large-size format for easy photocopying, the book includes 28 reproducible worksheets, strategy guides, and fidelity assessment tools. Purchasers get access to a Web page where they can download and print the reproducible materials. This book is in The Guilford Practical Intervention in the Schools Series, edited by Sandra M. Chafouleas.
