Prisoner’s insomnia prevalence, insomnia associated factors and interventions with sleep as an outcome: a review and narrative analysis

Abstract

Purpose Insomnia is highly prevalent in prisoners. The purpose of this paper is a review of research evidence on interventions with sleep as an outcome (2000 to 2020) and rates of insomnia prevalence and associated factors in prisons (2015 to 2020). Design/methodology/approach An internet-based search used Medline, PubMed, PsycINFO (EBSCOhost), Embase, Web of Science and Scopus. Seven interventions and eight sleep prevalence or sleep-associated factor papers were identified. Findings Intervention research was very limited and the quality of the research design was generally poor. Interventions such as cognitive behavioural therapy for insomnia (CBT-I), yoga and mindfulness can be beneficial in a prison setting. This review identified a high prevalence of insomnia in prisons across the world, which was supported by recent evidence. Factors associated with insomnia include anxiety, depression, post-traumatic stress disorder, personality disorder and pain. Research limitations/implications There is a need for appropriately powered randomised control trials of CBT-I in prisons and a need to use objective measures of sleep quality. Originality/value Due to a lack of an up-to-date review, this paper fulfils the need for a review of the evidence on interventions in prison settings with sleep as an outcome, rates of insomnia prevalence and associated factors in prisons.

Prevalence of insomnia and poor sleep quality in the prison population: A systematic review

“…Since the completion of the current review, a further relevant review has been published. Griffiths and Hina ( 2022 ) conducted a review of insomnia interventions in prisons, which included a secondary analysis of prevalence of insomnia. The search timeframe was within the one used in this review, and they had broader inclusion criteria.…”
