ABSTRACT
BACKGROUND AND OBJECTIVES: Planning and implementing prison-based substance use disorder (SUD) interventions are challenging. We wanted to understand why and how people in correctional settings (CS) use drugs and to explore what policies, environmental, and interpersonal factors influence substance use among incarcerated people. Using the Behavior Change Wheel (BCW) framework, we proposed a thematic map with intervention functions to reduce substance use in CS. METHODS: We used the Framework Method of qualitative analysis. We did snowball sampling for the incarcerated people with drug use (PWD) and convenience sampling for the staff. The in-depth interview sample comprised 17 adult PWD, three prison administrative, and two healthcare staff. We determined the sample size by thematic data saturation. We followed a mixed coding approach for generating categories, i.e., deductive (based on the BCW framework) and inductive. The study constructed the final theoretical framework by determining the properties of the categories and relationships among the categories. RESULTS: We identified eleven categories aligned with the BCW framework. The themes were prison routine, interpersonal dynamics of the incarcerated population, exposure to substance use, attitude of staff towards PWD, experience with prison healthcare, willingness (to reduce drug use) and coping, compassion, drug use harms, conflict between staff and residents, stigma, and family/peer support. The BCW framework aided the identification of potential intervention functions and their interactions with the organizational policies that could influence PWD's capability-opportunity-motivation (COM) and drug use behavior (B). CONCLUSION: There is a need to raise awareness of SUD prevention and intervention among decision-makers and revisit the prison policies.
