Mass incarceration poses a public health crisis in the United States as a major structural determinant of health [1]. Exposure to incarceration heightens risks of chronic conditions, including cardiovascular disease and cancer, while significantly increasing all-cause mortality [2]. Prior unethical research resulted in federal restrictions on research conducted on criminal-legal involved populations [3]. Varied interpretations of federal regulations have led to heterogenous operationalization of research systems, evidenced in varied state Department of Corrections (DOC) policies in state prisons. Ethical research is needed to measure health-related outcomes for those in prisons; however, these varied interpretations of federal regulations create barriers. We evaluated the accessibility of research-related information on publicly available websites of state DOCs.

Two state DOCs’ (Alaska and Hawaii) websites were unavailable; only 33 of the remaining 48 states’ research web pages were available. Less than half of states had web page–accessible policies available about consent, recruitment, or use of incentives for staff or incarcerated participants (Table 1). We received a response via phone or email from only 23 of the 25 DOC web pages that provided contact information. While similar in number, the states that provided information about incarcerated participants and those that provided information about involved staff only partially overlapped, and several only provided policies for group or the other.

We observed significant heterogeneity in the availability and content of state DOC websites and research web pages, with most DOCs having little information readily available. For instance, only 20 DOC web pages explicitly mentioned IRB requirements, and as few as 14 states had policies available describing staff payments. Barriers to accessing DOC-specific policies have impeded researchers interested in developing prison-based research questions and studies aiming to improve conditions and health outcomes in these settings [6,7]. By extension, the limited accessibility demonstrated herein could hinder future research. Furthermore, limited access to research can be harmful, as demonstrated by HIV’s impact on incarcerated populations [8]. The COVID-19 pandemic reenforced this and displayed how research partnership across carceral, academic, and public sectors are needed to mitigate harm [9,10]. Decreasing barriers and increasing the web-based availability of prison research policies is therefore a reasonable first step to support impactful and feasible research.

Our evaluation was cross-sectional, and websites may change rapidly, reflecting funding or policy, as evidenced by current DOC websites for Alaska and Hawaii that were not available for analysis in 2023. Repeat analysis may reveal changes to other DOC websites as well. Furthermore, public-facing information on prison-based research does not necessarily translate into actual collaboration between researchers and state DOCs, and assessments of virtual information do not capture existing relationships among researchers, prison-based populations, and DOCs. Further analysis should focus on the cascade of research projects (eg, submitted, approved, and published) in each state to better understand how this accessibility translates to research partnerships. Conceivably, increasing the digital availability of DOCs’ research policies will facilitate research initiation and partnerships to improve health outcomes for incarcerated individuals.
