Research

Our team has conducted dozens of program evaluations. When the results of our evaluations have relevance to the broader philanthropic and academic communities, we believe that disseminating the findings in academic journals and other outlets can be a viable strategy for having a bigger impact and promoting the sustainability of the partner's programming.

CCRE projects have led to the following academic publications.

  • Holmes, E., Campbell, M., James, W., and Matthews, K. 2020. "School Garden Programs: Academic and Non-Academic Outcomes." Forthcoming in Ecology of Food and Nutrition.
    • This research evaluates the impact of participation in school garden programs on student garden knowledge, self-perception, and standardized test scores. We collected pre and post-test data from fifth-grade students from schools in the Mississippi Delta for two years, compared student garden participants' Standardized Test and Reporting (STAR) scores with nonparticipant STAR scores, and conducted fieldwork, participant observation, and interviews in three school gardens for eight months during the 2017-2018 school year. While no effect on standardized test scores could be determined, results show that students' garden knowledge increased and students reported feeling positive about their future, teamwork, and leadership ability. These results were supported by observations of student joy, confidence, leadership, teamwork, and growth. Over time, these benefits to students may affect lasting changes in the agri-food system of the Mississippi Delta.

    • We test the effectiveness of Delta Futures, a comprehensive regional effort to improve the quality of teen pregnancy programming in thirteen counties of the Mississippi Delta, in changing attitudes, motivations, and self-reported intentions relating to abstinence, contraception, and sexual risk. Our analysis of survey assessments from over 3,000 participants reveals several findings relevant for practitioners of teen pregnancy programs and collaboratives: (1) Overall, we find evidence that the program improves participants' willingness to commit to using birth control, but not to pursue abstinence; (2) Abstinence intentions does, however, improve considerably for students who are sexually active; (3) We find improvement in motivations relating to birth control, perceptions of sexual risk, and to a lesser extent abstinence motivations; (4) We find statistically insignificant but counter-intuitive findings when comparing the effectiveness of an abstinence-only with an abstinence-plus curriculum; (5) We find more potent impacts among females, the sexually active, and individuals with low self-esteem; (6) We find evidence that contraception-related impacts are sustained up to twelve months.

    • Perinatal home visiting programs, in which healthcare professionals or social workers offer medical and social support to expectant mothers, have shown promising evidence for improving birth weight outcomes but have been understudied about rural or non-Hispanic black populations. This brief reports preliminary observations from one program situated among primarily non-Hispanic black women in a heavily rural area, which we demonstrate to be not only the most at-risk pregnancies but also some of the most overlooked in the literature. Using data from a home visiting program and aggregates from one county in the rural Mississippi Delta, we compare the incidence of low (LBW) and very low (VLBW) weight births of non-Hispanic black participants (n=109) to the rates among births to black non-participant women in the county (n=281) in 2015. Despite extreme poverty, higher rates of teen pregnancy, and lower rates of marriage than comparison groups, participation was associated with VLBW rates significantly lower than those of county non-participants in one-sample binomial and Fisher's exact tests, and a 26% lower rate of LBW that was not a significant difference in tests of association. The association between participation and lower LBW and VLBW incidence reinforces evidence that home visiting is an effective approach to ameliorating health disparities is highly isolated, cash-strapped regions.

    • This study examines whether a transition-to kindergarten program improves literacy test scores and whether such improvements last over 4 years. Transition-to-kindergarten programming is the supplemental effort, inside or outside the school, to prepare schools, children, and their families for kindergarten entry. Studies of the effectiveness of the programming have typically used behavior and literacy as outcomes, but, to our knowledge, no contemporary studies have measured outcomes beyond the fall of 1st grade, and none have disaggregated their findings to test results for African- American children in a rural setting (or all children in the setting of a rural, predominantly African-American school). Here, we follow participants and non-participants in an evidence-based transition-to-kindergarten program from K-entry to fall of 4th grade to test whether children who participated in the program entered Kindergarten, entered each subsequent grade, or had a growth pattern that demonstrated a statistical advantage over nonparticipants. We discuss our findings and their implications further.

    • Americans living in rural communities experience high rates of chronic disease while lacking access to adequate general and specialized medical care. Our research exhibits how a Patient Centered Medical Home (PCMH) can aid those living in areas where there is a shortage in primary care health professionals. Studying patients with type II diabetes from a poor, unhealthy, rural Mississippi community, we used electronic health records to analyze longitudinal patterns in patient health from PCMH and traditional primary care clinics. A PCMH approach resulted in improved disease maintenance compared to traditional primary care clinics. PCMH patients diagnosed with type II diabetes fell from 87% to 70% over a five-year period. Chronically ill PCMH patients adopted a continuity of care, adhering at a rate of 88% at their follow-up visits (compared to 23% for non-PCMH patients). Improvement efforts like PCMH clinics could serve as a model to decrease the national mortality disparity plaguing other poor, rural areas.

    • Using proprietary data of patient records from four medical clinics in the Mississippi Delta, this research utilizes a natural experiment design to explore if the patient centered medical home (PCMH) has a positive effect on chronic disease maintenance for low SES, majority African-American patients in a rural and medically underserved region. The patients are divided into two cohorts, those attending PCMH clinics (level 2) and those attending non-PCMH clinics. Each cohort is comprised of similar demographic, socioeconomic, and health (large proportion of diabetics) characteristics. HbA1c scores of the cohorts are compared at two time periods, baseline and six-month follow-up. PCMH patients report more uncontrolled diabetes at baseline but the trend reverses at follow-up, providing evidence that the PCMH model of primary care produces positive health outcomes for patients with diabetes in the sample area.
