School predictors of the intensity of implementation of school-based prevention programs: results from a national study.

Research has indicated that the effectiveness of school-based prevention programs is affected by the implementation quality of these programs. As the importance of implementation has become clearer, researchers have begun to examine factors that appear to be related to implementation quality. Data from a nationally representative sample of 544 schools were used to examine structural equation models representing hypothesized relationships among school and program factors and implementation intensity, controlling for exogenous community factors. Significant relationships were found between implementation intensity and several school and program factors, including local program development process, integration into school operations, organizational capacity, principal support, and standardization. Implications of these findings are discussed.
