Few prevention studies have examined the degree to which different measures of program implementation adherence predict youth outcomes. The current study was conducted with rural middle school youth participating in a longitudinal school-based preventive intervention program. Study participants' average age at the pretest assessment was 12.3 years. The association between program implementation ratings supplied by provider self-reports and trained independent observer reports were evaluated. In addition, the relationship between measures of implementation and youth outcomes were examined. Results indicated that although program providers tended to report higher implementation than independent observers, most ratings were correlated significantly across raters. Observer-reported implementation ratings significantly predicted several youth substance-related outcomes, while provider-reported self-ratings did not. Program provider characteristics predicted several youth outcomes. Findings suggest that there might be a social desirability bias in provider self-reported ratings of implementation and that caution must be used when interpreting self-reported ratings of implementation.
很少有预防研究考察过不同的项目实施依从性测量指标在多大程度上能够预测青少年的结果。本研究针对参与一项基于学校的纵向预防性干预项目的农村中学青少年开展。研究参与者在预测试评估时的平均年龄为12.3岁。对由服务提供者自我报告和经过培训的独立观察者报告提供的项目实施评分之间的关联进行了评估。此外，还考察了实施测量指标与青少年结果之间的关系。结果表明，尽管项目服务提供者倾向于报告比独立观察者更高的实施水平，但大多数评分在评分者之间存在显著相关性。观察者报告的实施评分显著预测了几个与青少年物质相关的结果，而服务提供者报告的自我评分则没有。项目服务提供者的特征预测了几个青少年结果。研究结果表明，在服务提供者对实施情况的自我报告评分中可能存在社会期望偏差，在解释自我报告的实施评分时必须谨慎。
