Links childhood maltreatment to sleep issues, suggesting shared genetic influences.
This study provides suggestive genetic evidence linking composite CM liability with selected sleep-related phenotypes, particularly self-reported DS, insomnia symptoms, and DN. Reverse-direction findings may reflect shared genetic liability, gene-environment correlation, reporting-related mechanisms, or broader familial pathways rather than temporal effects of adult sleep traits on CM. Given modest effects and uneven sensitivity support, findings should be interpreted cautiously.
