0292 Development and Validation of the Sleep Conflict Scale in Couple Relationships

Abstract Introduction Although there is considerable sleep concordance between partners in couple relationships, less known about practices them and if conflict around habits, preferences, behaviors. Past empirical work suggests that couples who share the same sleep-wake preferences (i.e., morning vs. night people) report higher marital adjustment relational conflict. And yet mechanism through which this occurs unknown. One such sleep-related whereby disagree their partners' rituals causing Methods The present study utilizes two samples to validate Sleep Conflict Scale (SCS), one individuals relationships other sample of paired (dyadic data). scale a 5-item measure includes items as "My partner I routines habits" "Our relationship negatively affected by our differences". In order identify underlying factor structure SCS, several criteria was assessed determine suitability for analysis, including bivariate correlations, Kaiser-Meyer-Olkin Measure Sampling Adequacy, Bartlett’s test Sphericity. Composite scores were computed internal consistency conducting Cronbach Alpha reliability estimates. We tested convergent validity identifying associations SCS psychological health measures. Finally, using dyadic sample, we also structural equation model on both hygiene quality. Results revealed fit solution five summed or mean score can be used. demonstrated excellent external when compared associated with worse poorer quality partners. Conclusion analyses provided support psychometrically sound measure, it demonstrates single structure, highly reliability, qualitatively different than used primary secondary care settings would benefit from intervention especially adherence low.
