Using Ecometric Data to Explore Sources of Cross-Site Impact Variance in Multi-Site Trials.

In 2003, Bloom, Hill, and Riccio (BHR) published an influential paper introducing novel methods for explaining the variation in local impacts observed in multi-site randomized control trials of socio-economic interventions in terms of site-level mediators. This paper seeks to improve upon this previous work by using student-level data to measure site-level mediators and confounders. Development of asymptotic behavior backed up with simulations and an empirical example. Students and training providers. Two simulations and an empirical application to data from an evaluation of the Health Professions Opportunity Grants (HPOG) Program. This empirical analysis involved roughly 6600 participants across 37 local sites. We examine bias and mean square error of estimates of mediation coefficients as well as the true coverage of nominal 95-percent confidence intervals on the mediation coefficients. Simulations suggest that the new methods generally improve the quality of inferences even when there is no confounding. Applying this methodology to the HPOG study shows that program-average FTE months of study by month six was a significant mediator of both career progress and long-term degree/credential receipt. Evaluators can robustify their BHR-style analyses by the use of the methods proposed here.

Association between Depression and Aggression in Rural Women.

Rural women represent approximately 20% of women living in the United States, yet research on the specific mental health needs of rural women is limited. Given the well-recognized gender-linked difference in depression rates, its correlated depressive symptoms in women still need much investigation. While emerging notions of depression in men embrace potential symptoms related to irritability and aggression, less research has focused on the potential role of aggression in depressed women. This connection may be particularly relevant for rural women who face unique mental health stressors in comparison to their urban counterparts. The purpose of this study was to examine if aggression is linked to depression for rural women in order to identify potential unique symptomatology and presentation for rural women. As part of a larger initiative, a sample of 54 participants was recruited from the patient population at a Federally Qualified Health Center (FQHC) in rural southeast Georgia to participate in a quantitative survey. The survey explored demographics, depression, and aggressive behavior. Mean total score of aggression in depressed women was significantly higher than non-depressed women (p < 0.001), and within the entire sample depression scores were significantly related linearly to aggression, with aggression explaining 16% of the variance found in depression scores (ß = .399, r2 = .159, p = 0.003). This study suggests that aggressive behavior may be linked to depression for rural women, and underscores the need for future research investigating if depression presents differently for rural women.
