Reporting of validity from school health promotion studies published in 12 leading journals, 1996-2000.

A targeted review was conducted of school-based, controlled intervention studies that promoted good nutrition, physical activity, or smoking cessation/prevention, and were published in one of 12 leading health behavior journals between 1996 and 2000. The RE-AIM framework was used to evaluate the extent to which each paper reported on elements of reach, efficacy, adoption, implementation, and maintenance. Thirty-two publications were reviewed. Reporting rates across the RE-AIM dimensions varied substantially: Reach = 59.3%; Efficacy = 100%; Adoption = 14.8%; Implementation = 37%; Maintenance = 25.9% for individuals, 0% for schools. Few studies reported if characteristics of the study sample were representative of those found in the broader population of students or schools. Among studies reporting on the RE-AIM dimensions, participation rates generally were high (median 82%), adoption rates were moderate (median 72.5%), and reports of implementation were high (87%). To increase the potential to translate controlled research to "real-world" practice conditions, a stronger emphasis should be placed on reporting the representativeness of the sample of students and schools.
