Work‐family Spillover among Japanese Dual‐earner Couples: A Large Community‐based Study

Abstract

Work-family Spillover among Japanese Dual-earner Couples: A Large Community-based Study: Kyoko SHIMADA, et al. The University of Tokyo Graduate School of Medicine, Department of Mental Health-Objectives: To examine the effects of multiple types of work-family spillover (work-to-family negative spillover, WFNS; family-to-work negative spillover, FWNS; and work-family positive spillover, WFPS) on psychological distress among Japanese dual-earner couples with preschool children. Methods: 2,346 parents completed questionnaires measuring workfamily spillover, work-and family-specific variables (i.e., job demands and resources, family demands and resources), and psychological distress. A hierarchical multiple regression analysis was conducted by entering demographic characteristics (gender, age, age of the youngest child, and job contract) in step 1, job demands and resources in step 2, family demands and resources in step 3, work-family spillover in step 4, and three twoway interactions between types of work-family spillover and gender in the final step. Results: Both WFNS and FWNS were positively related to psychological d i s t r e s s a f t e r c o n t r o l l i n g f o r d e m o g r a p h i c characteristics and domain specific variables (i.e. job and family demands/resources), and FWNS (β=0.26) had a stronger relation with psychological distress than WFNS (β=0.16). Although WFPS was significantly and negatively related to psychological distress, the relationship was weak (β=-0.05). In addition, two-way interactions of WFNS and FWNS with gender were found; the impact of both WFNS and FWNS on psychological distress is stronger for females than for males. No significant interaction effect was observed between WFPS and gender. Conclusions: In this study of Japanese dual-earner couples with preschool children, work-family negative spillover had a stronger relationship with psychological distress than positive spillover. Gender had a moderating effect on the relationship between negative spillover and psychological distress. (J Occup Health 2010; 52: 335-343)

Maternal Working Hours and Early Childhood Overweight in Japan: A Population‐based Study

“…Although the information concerning the time spent on child care was not available in this study, this may explain the present finding of children whose mothers work ≥8 h/day. Thirdly, mothers who work for relatively short hours outside the home may experience good work-life balance, and this may produce positive affective states, including a sense of security for being "accepted" within society as well as home 32,33) . Positive affective states (e.g., empowerment) are in turn hypothesized to increase motivation for child care 16) .…”

The relationship between family adjustment and expatriate performance

“…Spillover has a bi-directional relationship whereby work influences family life, and family influences work life (Shimada, Shimazu, Bakker, Demerouti & Kawakami, 2010). Spillover is relevant for this study as the experiences at home, may spillover to the performance levels at work and vice versa.…”

The effects of workplace psychosocial factors on whether Japanese dual-earner couples with preschool children have additional children: a prospective study

“…Active jobs are associated with a feeling of mastery which might reduce the psychophysiological impact of stressful work situations22 ) . Proactive attitudes toward work have previously been found to be associated with a positive work–family spillover18, 24 ) , which might in turn lead to having additional children.…”

“…The TWIN study aimed to examine intra-individual (spillover) and inter-individual (crossover) processes of well-being among dual-earner couples with preschool children in Setagaya Ward, Tokyo, Japan. All TWIN I participants18 ) were invited to participate in TWIN II (N=321 families). We also approached all day-care centers (N=22) in another ward, Meguro, with the permission of the ward day-care division.…”
