Session Abstract (150 words): 

This paper describes a real-world example of Propensity Score Matching (PSM) within the context of a foster care sub-study. The focus is on theory and methodology with less attention to study findings.

The paper will start with a brief review of the PSM literature, discuss the pros and cons of PSM usage, and cover implementation steps of PSM in this specific study, to include SPSS and R. Findings from the study will be used to illustrate differences in outcomes for the treatment group, all controls, and matched controls on a number of different measures. This last part of the discussion will help showcase the impact of PSM on evaluation outcomes; especially with respect to statistically significant differences and their associated effect sizes.
