Objective: This study evaluated: (a) associations between long-term care residents' mental health disorder diagnoses and their pain self-reports and pain treatments, and (b) the extent to which communication, cognitive, and physical functioning problems help explain disparities in the pain and pain treatments of long-term care residents with and without mental health disorders. Method: Minimum Data Set 3.0 records of 8,300 residents of Department of Veterans Affairs Community Living Centers were used to determine statistically unadjusted and adjusted cross-sectional associations between residents' mental health diagnoses and their pain and pain treatments. Results: Residents diagnosed with dementia and serious mental illness (SMI) were less likely, and those diagnosed with depressive disorder, post-traumatic stress disorder (PTSD), and substance use disorder (SUD) were more likely, to report recent, severe, and debilitating pain. Among residents affirming recent pain, those with dementia or SMI diagnoses were twice as likely to obtain no treatment for their pain and significantly less likely to receive as-needed pain medication and non-pharmacological pain treatments than were other residents. Those with either depressive disorder or PTSD were more likely, and those with SUD less likely, to obtain scheduled pain medication. In general, these associations remained even after statistically adjusting for residents' demographic characteristics, other mental health disorder diagnoses, and functioning. Conclusion: Long-term care residents with mental health disorders experience disparities in pain and pain treatment that are not well-explained by their functioning deficits. They may benefit from more frequent, thorough pain assessments and from more varied and closely tailored pain treatment approaches.
