ABSTRACTThis study examined whether one partner’s additional resources obtained from a workplace intervention influence the other partner’s perception of having those resources at home (crossover of resources). We also examined whether one partner’s decreased stress by increased work resources crosses over to the other partner’s stress levels (crossover of well-being). Longitudinal data came from IT employees and their married/cohabiting partners in midlife (N = 327). A randomized workplace intervention significantly increased employee-reported schedule control at the 6-month follow-up, which, in turn, increased partner-reported employees’ work schedule flexibility to handle family responsibilities at the 12-month follow-up. The intervention also decreased partners’ perceived stress at the 12-month follow-up through the processes by which increases in schedule control predicted decreases in employees’ perceived stress, which further predicted decreased levels of partners’ perceived stress. Notably, crossover of resources and well-being were found in couples who lived with children in the household, but not in couples without children. Our findings suggest that benefits of workplace support can permeate into the family domain, by increasing partner-perceived family resources and well-being.

AbstractObjectives For most partnered adults, sleep is not an individual-level behavior―it is a shared health behavior with a partner. This study examined whether perceived nightly sleep duration and sleep quality covaried within couples and whether the unique influence of partner sleep on individual sleep differed by gender. Design Eight consecutive days of diary data. Participants \US\ hotel employees and their spouses/partners (N = 76 from 38 couples, 600 daily observations). Measurements Each day, couples separately reported their previous night's sleep duration (in hours) and sleep quality (1 = very unsatisfactory to 5 = very satisfactory). Analyses adjusted for sociodemographic, family, work, and day-level characteristics. Results Dyadic multilevel modeling revealed positive covariation in nightly sleep duration within couples. After controlling for the effects of contextual covariates, partner influence on individual sleep duration was more apparent in men's sleep. When a female's sleep duration was longer or shorter than usual, their male partner's sleep duration was also longer or shorter than usual, respectively. However, a female's sleep was not significantly predicted by her male partner's sleep duration after taking into account the effects of her sleep on the male partner's sleep and contextual covariates. Sleep quality covaried on average across days between partners, and this association did not differ by gender. Conclusions Our results demonstrate positive covariation in sleep duration and sleep quality within couples. Couples' sleep duration covaried night-to-night, and their sleep quality covaried on average across days. A male's sleep duration is predicted by the female partner's sleep duration but not vice versa. Future research should examine health consequences of couple sleep covariation.
