Pain intensity, depressive symptoms, and functional limitations among older adults with serious mental illness.

Objective: To examine pain-related activity interference as a mediator for the relationship between pain intensity and depressive symptoms among older adults with serious mental illness (SMI).

Method: Ordinary least-squares regressions were used to investigate the mediation analysis among older adults with SMI (n = 183) from community mental health centers. Analyses used secondary data from the HOPES intervention study.

Results: Higher pain intensity was associated with greater pain-related activity interference. Higher pain intensity and pain-related activity interference were also associated with elevated depressive symptoms. Finally, greater pain-related activity interference significantly mediated the association between higher pain intensity and elevated depressive symptoms.

Conclusions: These findings demonstrate that pain and depressive symptoms may be linked to functional limitations. Clinicians and researchers in the mental health field should better address pain-related activity interference among older adults with SMI, especially among those with higher pain intensity and elevated depressive symptoms.
