Behavioral health (BH) problems are common in the military and can adversely affect force readiness. Research suggests that primary care-behavioral health (PCBH) integration can improve BH outcomes by making high-quality BH care available in more accessible settings. However, sustaining high-quality implementation of PCBH is challenging. The authors conducted a process evaluation of the PCBH program in the military health system to understand why the program is working as it is and provide recommendations for quality improvement. They conducted semistructured interviews, rigorously coded the qualitative data to identify causal links, and created and validated causal loop diagrams that provide a visualization of how the system is working. Findings fall into four key areas: staffing and capabilities, valued tasks, program stewardship, and fostering program awareness and support. Overall, the authors found that the PCBH program is highly valued by primary care staff. However, the PCBH care model is inconsistently adhered to, owing to a combination of staff preferences, local pressures, and lack of knowledge of PCBH staff roles. Recommendations are offered to improve program implementation.
