Toward Positive Youth Development

Many youth development programs are designed to improve youth outcomes by improving the quality of social interactions occurring in classrooms, athletic teams, therapy groups, after-school programs, recreation centers, or other group settings. In evaluating such programs, it becomes essential to assess the impact of the program on the “group quality,”; that is, the quality of the social interactions that occur in such group settings. It follows that the reliable measurement of group quality becomes important to the success of the evaluation. Low reliability will weaken the statistical power of the evaluation to detect program effects on group quality. This chapter introduces how to assess the reliability of measures of group quality and how to design evaluation studies that have adequate statistical power to detect impacts on group quality.
