RESUMO
BACKGROUND: People with intellectual disabilities are more likely to experience sleep problems, which can affect quality of life, physical health, mental health and well-being. METHODS: An integrative literature review was conducted to investigate what is known about behavioural sleep disturbances in people with an intellectual disability. The search used the following databases: Scopus, PsycInfo and Cinahl, to find papers published since 2015. RESULTS: Within intellectual disability research, sleep appears as a common issue due to its high prevalence, negative relationships with an individual's physical and mental health, their quality of life, and impact of sleep problems on family or carers. The growing evidence base appears to support the use of behavioural, lifestyle and pharmacological interventions to improve sleep in people with an intellectual disability. CONCLUSION: A wide array of literature provides evidence that people with intellectual disabilities are affected by and need support with their sleep.
