Measuring Success: Evaluation Designs and Approaches to Assessing the Impact of School-Based Health Centers

Since the founding of the first school-based health centers (SBHCs) >45 years ago, researchers have attempted to measure their impact on child and adolescent physical and mental health and academic outcomes.A review of the literature finds that SBHC evaluation studies have been diverse, encompassing different outcomes and varying target populations, study periods, methodological designs, and scales.A complex picture emerges of the impact of SBHCs on health outcomes, which may be a function of the specific health outcomes examined, the health needs of specific communities and schools, the characteristics of the individuals assessed, and/or the specific constellation of SBHC services. SBHC evaluations face numerous challenges that affect the interpretation of evaluation findings, including maturation, self-selection, low statistical power, and displacement effects.Using novel approaches such as implementing a multipronged approach to maximize participation, entering-class proxy-baseline design, propensity score methods, data set linkage, and multisite collaboration may mitigate documented challenges in SBHC evaluation.
