A Quantitative Evaluation of Program Implementation and Outcome in a Demoralized Urban School

ABSTRACT
A second report on the intervention program in this school provides a quantitative account of the implementation and outcome evaluation of a social skills training intervention intended to reduce student problem behavior. Implementation data show that the program was only 68% implemented due to interruptions that characterized the school environment (and on which the qualitative study sheds light), and was implemented to different degrees in two successive semesters. Outcome data showed that the intervention nevertheless had some positive effects on student conduct, less victimization in school, and more positive peer associations and reduced the proportion of students who left school when data for the intervention group are compared with a comparison group i the same school net of statistical controls for initial student characteristics. Simple quantitative analyses revealed instances of teacher noncompliance with efforts to collect data, and that school disciplinary data lacked validity, so that it is necessary to rely on data specifically collected to make evaluation possible. Specific intervention programs may offer minimal benefits if the school environment makes implementation difficult.
