Associations between parental relationship dissolution and child sleep: A systematic review.

Parental relationship dissolution is considered one of the most common adverse childhood experiences. Although sleep is crucial for healthy development of children and very sensitive to environmental changes, it is poorly studied in the context of parental relationship dissolution. The aim of the current study was to systematically review and critically assess the existing literature on the associations between parental relationship dissolution and child sleep (0-18 years old; registered on PROSPERO (CRD42021272720)). PsycInfo, MEDLINE, Scopus, ProQuest Dissertations and Theses Global, Social Work abstracts, and Web of Science Core Collection were searched. Published empirical quantitative studies were included if they reported statistics regarding the association between parental relationship dissolution and any child sleep variable. Out of the 358 articles screened, 14 articles met inclusion criteria and reported on several sleep dimensions: sleep quality, dreams and nightmares, and sleep disorders (enuresis, night terrors, and bruxism). Out of the 14 articles, six were longitudinal studies and eight were cross-sectional studies. While most studies found that parental relationship dissolution was associated with some indices of poorer child sleep, studies were generally of low to moderate quality. Health professionals should assess child sleep in the context of a parental relationship dissolution.
