Our objective was to investigate the hypothesis that psychological resources, including resilience, social connections, and internal locus of control, separately and in additive combinations, would be associated with selected pain outcomes: 1) days of opioid use and 2) medical/drug expenditures over 2 years. A mailed survey was sent to a stratified sample of older adults age≥65 with diagnosed back pain, osteoarthritis, and/or rheumatoid arthritis. Each of the resources was dichotomized as high/low and/or counted with equal weighting. Among respondents (N=3,131), the prevalence of mild/no and moderate/severe pain severity was 59% and 41%, respectively. As hypothesized, each resource was associated with lower levels of pain; additively, reported pain severity decreased as the number of resources increased. For moderate/severe pain, there was reduced opioid use among those with more resources; and, for mild/no pain, decreased medical/drug expenditures among those with ≥2 resources. Interventions that integrate psychological resources may enhance their effectiveness.
