National estimates of mental health service use and unmet needs among adult cancer survivors

Abstract

Cancer survivors are at elevated risk for developing mental health (MH) disorders. This study assessed MH service use and unmet service needs among a nationally representative sample of cancer survivors. Respondents aged 18 to 64years were identified from the 2015-2018 National Survey of Drug Use and Health data. Outcomes assessed past-year MH service use and self-reported unmet MH needs. Outcomes were compared between respondents who reported a cancer history (survivors) and those who did not (controls), descriptively and in adjusted analyses controlling for sociodemographic factors and health status. Analyses were stratified by age groups (18-34, 35-49, and 50-64years). Comparing 3540 survivors with 149,843 controls, within each age group, a higher proportion of survivors than controls received any MH service (P values<.05); this difference persisted among those aged 35 to 49years (P=.004) in fully adjusted models. Moreover, a higher proportion of survivors than controls reported an unmet need for MH care; this difference was larger among young adults aged 18 to 34years (20.8% vs 9.0%; P<.001) than those aged 35 to 49years (9.4% vs 5.3%; P<.001) and 50 to 64years (4.8% vs 3.4%; P=.029). In fully adjusted models, the survivor-control difference in self-reported unmet MH needs persisted among young adults (24% relative increase; P=.023). Among cancer survivors, young adult survivors had the highest likelihood of reporting unmet MH needs. This nationally representative study found an increased perception of unmet needs for MH care among cancer survivors, particularly among young adult survivors, compared with the general population without cancer.
