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.

The primary objectives were to investigate the association of physical activity levels with 1) loneliness and social isolation; 2) protective factors: resilience, purpose-in-life, and perception of aging; and 3) the impact of these factors on healthcare expenditure patterns across physical activity levels. The study sample was identified from adults age ≥65 who completed a health survey in 2018 or 2019 (N=6,652). Among survey respondents, the prevalence of low, moderate, and high physical activity levels was 29%, 31%, and 41%, respectively.

Objectives: Using data from a large random sample of U.S. older adults ( = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects.

Our objective was to investigate three levels of resilience (low, medium, and high), identify associated characteristics, and measure the impact of increasing resilience on quality of life (QOL), healthcare utilization and expenditures, and preventive services compliance. The study sample was identified from adults age ≥65 who completed surveys during May-June 2019 (N=3,573). Other protective factors, including purpose-in-life, optimism, locus of control, and social connections, were dichotomized as high/low and counted with equal weighting (0 to 4).

Objectives: Loneliness and social isolation are described similarly yet are distinct constructs. Numerous studies have examined each construct separately; however, less effort has been dedicated to exploring the impacts in combination. This study sought to describe the cumulative effects on late-life health outcomes.

Our objective was to investigate the additive properties of five psychosocial protective factors: purpose-in-life, resilience, optimism, internal locus of control and social connections. Self-reported psychological (depression, stress) and physical (health status, functionality) health outcomes and measured healthcare utilization and expenditures were included. The study sample was identified from adults age ≥65 who completed a health survey during May-June 2019 (N = 3,577).

Tramadol is a low-level opioid increasingly recommended to treat moderate-to-severe acute and chronic pain. Although characterized as having fewer opioid-related adverse events, the longer term safety of tramadol use among older adults has not been thoroughly documented. Thus, the primary objective was to examine the risk of safety events associated with chronic tramadol use compared to other chronic opioid use or no opioids among older adults with osteoarthritis.
