Psychological treatment integrity refers to the extent to which a treatment intervention is implemented as intended in evidence-based practice; that is competently, consistently, and accurately. With discussion of treatment integrity largely scattered throughout the literature, this text is presented as the first comprehensive source on the current state of research on the conceptualization, assessment, and promotion of treatment integrity in psychology, education, and related fields. Twelve chapters summarize conceptual and empirical work on treatment integrity, situate the issue within ethical and legal context, cover both issues of concern to both practitioners and researchers, review assessment and promotion strategies based on research findings, and discuss implementation practices across intervention types and service-delivery models.
