The purpose of this study was to explore the influence of conjugal congruence on FWE and family satisfaction. In addition, we also examined the crossover of FWE from husbands to wives and vice versa. We used FWE for examining the existence of mediation effects in between conjugal congruence and family satisfaction. Therefore, we used conjugal congruence as independent variable, FWE as mediator variable, and family satisfaction as dependent variable to probe into the relation among the conjugal congruence, FWE and family satisfaction. By using the structured questionnaires, 490(245 pairs) of married couples in Taiwan, who is in double-income family with children, returned valid responses. The APIM analysis showed that there is significant positive correlation between the conjugal congruence and FWE. FWE partially mediated the relationships between conjugal congruence and family satisfaction .Furthermore, actor effect is stronger than partner effect in terms of both the husband or the wife. We also provided some practical recommendations for organizations and future research at the end of this study.
