Since the founding of the first School-Based Health Centers (SBHCs) over 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.
Utilizing novel approaches such as implementing a multipronged approach to maximize participation, entering-class proxy baseline design, propensity score methods, dataset linkage, and multisite collaboration may mitigate documented challenges in SBHC evaluation.
