Because of age-related changes in sleep patterns, older adults may get less sleep than the recommended amount and experience decreased performance in daytime activities as a result. This article examines the evidence for the effectiveness of interventions within the scope of occupational therapy addressing sleep. Thirteen Level I studies met inclusion criteria and were categorized into three themes: (1) one-to-one single-component interventions, (2) one-to-one multicomponent interventions, and (3) group multicomponent interventions. Strong evidence supports cognitive–behavioral intervention strategies for older adults that include relaxation, sleep hygiene education, problem solving, and physical exercise, among others, delivered one to one or in a group. Routine use of these interventions is recommended.
