Addressing patients' religion and spirituality (R/S) needs has been associated with positive health outcomes. However, despite receiving extensive training in spiritual assessment and care, chaplaincy services are primarily confined to inpatient settings, with few studies occurring in outpatient settings. The study sought to understand mental health providers' views about what shaped provider and patient motivation to engage in R/S discussions and seek referrals to chaplaincy services. We conducted five one-hour focus group sessions with a total of 38 staff members and thematically analyzed the resulting session and field notes. We identified four themes concerning provider knowledge and attitudes about R/S and chaplaincy services: Staff Information Needs, Staff Motivation to Discuss R/S and Refer, Patient Motivation to Use Chaplaincy Services, and Chaplain Accessibility. The study findings suggest that providers in outpatient substance use treatment clinics in the Veterans Health Administration are receptive to learning about R/S care and the possibility of expanding chaplaincy services. However, staff have misconceptions about the roles and responsibilities of chaplains. Attitudes about and experiences with R/S discussions varied. Trust and confidence in the benefits of chaplaincy services may be improved among both providers and patients by increasing chaplains' accessibility and visibility within these outpatient settings.
