The overarching purpose of the study was to investigate the role of three types of social support (i.e., spousal, childcare, and organizational support) in relation to work-family conflict (WFC) in dual-earner families with children ages 0-6 years. The relationship of WFC to psychological well-being and well-being in the domain of family was explored. Finally, the relationship of spousal support to psychological well-being and marital satisfaction was examined. A total of 434 participants (237 mothers, 197 fathers) in dual-earner families in Turkey with at least one preschool child participated in the study. The relative impact of childcare, spousal support, and organizational support on WFC and outcome variables was tested simultaneously for both men and women through structural equation modeling. Spousal support was related to WFC for women, whereas both spousal and organizational support were related to WFC for men. WFC had a negative relationship with psychological well-being, marital satisfaction, and parental role performance for both men and women. Implications of the results in relation to changing gender roles in a cultural context that is characterized by high collectivism and low gender egalitarianism are discussed.
