Abstract

Objective:This DNP project evaluated the effectiveness of a five-week educational intervention on adolescents’ knowledge of prediabetes, awareness, and intentions to adopt healthy lifestyle behaviors. Method and Intervention:Youth aged 13 to 18 years participated in five 40-minute school-based workshops. Outcomes were measured using the Adolescent Diabetes Awareness Test (ADAT), Health Belief Model (HBM), and Centers for Disease Control and Prevention (CDC) workshop evaluation. Effect sizes and 95% confidence intervals (CIs) were used to determine clinical relevance. Results:The intervention had a large, clinically relevant effect on prediabetes knowledge and awareness measured by the ADAT (Hedges’ g = 1.10) and CDC evaluation (Rosenthal’s r = .65), with 95% CIs excluding zero. The effect on intentions to adopt healthy lifestyle behaviors was minimal (HBM Hedges’ g = −0.14 to 0.23; 95% CIs including zero). Conclusion:Participants found the workshops relevant and expressed intentions to applythe information learned. School-based prediabetes education may improve adolescent knowledge and awareness; however, additional strategies may be needed to promote sustained lifestyle behavior change.
