title: Typology of delivery quality: latent profile analysis of teacher engagement and delivery techniques in a school-based prevention intervention, keepin' it REAL curriculum.
abstract: Enhancing the delivery quality of school-based, evidence-based prevention programs is one key to ensuring uniform program effects on student outcomes. Program evaluations often focus on content dosage when implementing prevention curricula, however, less is known about implementation quality of prevention content, especially among teachers who may or may not have a prevention background. The goal of the current study is to add to the scholarly literature on implementation quality for a school-based substance use prevention intervention. Twenty-five schools in Ohio and Pennsylvania implemented the original keepin' REAL (kiR) substance use prevention curriculum. Each of the 10, 40-45 min lessons of the kiR curriculum was video recorded. Coders observed and rated a random sample of 276 videos reflecting 78 classes taught by 31 teachers. Codes included teachers' delivery techniques (e.g., lecture, discussion, demonstration and role play) and engagement with students (e.g. attentiveness, enthusiasm and positivity). Based on the video ratings, a latent profile analysis was run to identify typology of delivery quality. Five profiles were identified: holistic approach, attentive teacher-orientated approach, enthusiastic lecture approach, engaged interactive learning approach and skill practice-only approach. This study provides a descriptive typology of delivery quality while implementing a school-based substance use prevention intervention.
