Although sleep problems and thesalience of marital ties increase with age, few studies have tested links between partners’ sleep and marital quality with older samples. Therefore, we investigated longitudinal and bidirectional within-and between-person associations between sleep and marital quality in couples aged 50 + (M = 63.12; SD = 7.87) . Using dyadic random intercept cross-lagged panel models, we tested associations between multiple domains of sleep (i.e., insomnia and subjective sleep quality) and marital quality (i.e., support and strain) over three waves of data spanning eight years in a nationally representative sample of 2,343 couples from the English Longitudinal Study of Ageing. Women’s reports of greater spousal strain predicted increases in their own insomnia symptoms and decreases in their subjective sleep quality over time. Additionally, women’s higher-than-average perceptions of spousal support predicted men’s later improvements in subjective sleep quality. No significant cross-lagged effects emerged between insomnia and spousal support, nor did we detect partner effects between spousal strain and subjective sleep quality. These findings suggest that women’s reports of marital quality are more consequential for both partner’s sleep, emphasizing the importance of considering gendered processes and interpersonal dynamics when examining the reciprocal links between sleep and relationship functioning across time.  \nAbstract citation ID: igaf122.3549  \nBIDIRECTIONAL LINKS BETWEEN SLEEP AND  \nMARITAL QUALITY: AN EIGHT-YEAR  \nLONGITUDINAL STUDY OF OLDER COUPLES  \nHanamori Skoblow, Eunjin Tracy, and Megan Gilligan, University of Missouri, Columbia, Missouri, United States  \nThe Model of Dynamic Association Between Relationship Functioning and Sleep positions sleep as a fundamentally dyadic","cbCaitQizh52s7NM","https://ap.wps.com/l/cbCaitQizh52s7NM","pdf",931236,"English","# Study focus\n## Sleep and marital quality dimensions\n# Methods\n## Dyadic random intercept cross-lagged panel models\n## Data source and sample\n# Results\n## Gender-specific cross-lagged associations\n## Null effects\n# Implications","[{\"question\":\"What relationship between sleep and marital quality did the study investigate?\",\"answer\":\"It tested bidirectional within- and between-person associations between sleep (insomnia and subjective sleep quality) and marital quality (support and strain) over three waves across eight years.\"},{\"question\":\"How were the analyses conducted?\",\"answer\":\"The study used dyadic random intercept cross-lagged panel models to assess longitudinal, reciprocal effects between partners while accounting for dyadic structure.\"},{\"question\":\"What were the main findings about gender and partner effects?\",\"answer\":\"Women’s reports of greater spousal strain predicted increases in their own insomnia and decreases in their subjective sleep quality; women’s higher-than-average perceptions of spousal support predicted men’s later improvements in subjective sleep quality.
