A conceptual framework for drug treatment process and outcomes

Evidence from specialized treatment evaluations and large-scale natural studies of treatment effectiveness is organized conceptually into a "treatment model" for summarizing how drug treatment works. Sequential relationships between patient and treatment program attributes, early patient engagement, recovery stages, retention, and favorable outcomes are discussed--along with behavioral, cognitive, and skills training interventions that have been shown to be effective for enhancing specific stages of the patient recovery process. Applications of the treatment model for incorporating science-based innovations into clinical practice for improving early engagement and retention, performance measurements of patient progress, program monitoring and management using aggregated patient records, and organizational functioning and systems change also are addressed.
