Alcohol Use in Older Adults: A Systematic Review of Biopsychosocial Factors, Screening Tools, and Treatment Options

Alcohol use among older adults, often denied, is a real public health problem in view of the harmful consequences it induces. The objective of this systematic review was to identify articles on the biopsychosocial factors, assessment tools, and treatment options that have proved useful for the early detection and management of alcohol use among older adults. With a view to producing a narrative synthesis from several databases, 66 articles were identified and studied, of which 45.4% (n = 30) were published between 2015 and 2020. The review is reported according to PRISMA guidelines. Although differences appear to exist between the samples studied, the analyses show that biopsychosocial factors such as quality of life, well-being, emotions, perceived stress, coping strategies, and mood disorders are associated with unhealthy alcohol use. Psychosocial factors such as strong social support appear to be correlated with low levels of alcohol use and abstinence. In general, the tools used to screen for alcohol use are AUDIT, CAGE, DPI, CARET, and SMAST-G. Interventions to prevent and manage alcohol use in older adults include CBT and brief interventions. This review of the literature provides a better understanding of which assessment tools should be used for screening. Emphasis should be placed on process-oriented scientific studies, which to date do not exist. Psychological processes mediated by biopsychosocial factors would enable the development of effective prevention interventions to be conducted in order to improve the quality of life of older adults.
