Interagency Meeting on Subgroup Analysis

Subgroup analysis, broadly, aims to measure change within and between groups. The challenges in designing research to examine subgroups, the analysis of the data and the interpretation of the results are critically important to answer the question that comes up most regularly in policy-relevant research: What works for whom? In September 2009 the Administration for Children and Families, along with other federal partners convened a meeting of experts to discuss the state of the field. Presentations at the meeting centered on innovative methods for conducting subgroup analysis and a discussion of guidelines for interpretation and reporting of subgroup analyses in prevention and intervention research.
