Abstract
Background: Mental resilience has emerged as a recent focus within the context of positive psychology. Resilience is a potentially modifiable construct. Some preliminary evidence from experimental studies as well as clinical populations has indicated that sleep may be related to mental resilience, but little is known about this relationship in healthy populations. Sleep is a complex with multi-factorial outcome, although the majority of research effort has focused on sleep duration and sleep quality. Our systematic review and meta-analysis will identify original research data from observational studies to assess if sleep duration and/or sleep quality is associated with levels of psychological resilience amongst healthy children, adolescents and adults. We hypothesize that there will be a positive association between sleep duration/quality and mental resilience across all age groups. Methods: A comprehensive, systematic search for literature will be conducted in June 2020 (LÖ), covering a total of eight academic databases (PubMed, Embase, PsycInfo, PsycArticles, CINAHL, Scopus, Web of Science and Academic Search Complete). Sources for grey materials will also be included and experts in the field will also be contacted for inclusion of unpublished data. PubMed and PubMed’s MeSH terms were used to develop the search strategy and systematically identify relevant search terms. Two authors (IG & AA) will screen the articles independently, and a third researcher (TA) will resolve discrepancies. The primary outcome is mental/psychological resilience. The systematic review will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.Discussion: The results of our systematic review and meta-analysis are intended to be published in an appropriate scientific peer-reviewed journal and will be made publicly available. The findings from our project are envisioned to inform and educate the public as well as healthcare and education systems, globally. Our systematic review protocol has been peer-reviewed and is currently registered in the international database, PROSPERO.Systematic review registration: CRD42020191119 (submitted on 2 July 2020).
