Objective Paternal involvement in child-rearing is an action goal of Healthy Parents and Children 21 (Tier 2), and should be actively promoted. Clarifying the related factors may contribute to countermeasures for promoting paternal involvement in child-rearing. This study aimed to examine the association between fathers' gender role attitudes and social support from their spouses (i.e., the mothers of the children) and their involvement in child-rearing.Methods We obtained the data of fathers involved in childcare (aged 25-50 years; all full-time workers) through an internet research company. The paternal involvement in childcare scale (11 items, 4-point scale, e.g., "taking care of children," "cooking") was used as the dependent variable. The independent variables were gender role attitude ("Husbands should work outside the home and wives should take care of the home," 4-point scale) and social support from the mothers of the children (including appraisal, emotional, and instrumental support). The control variables were father's age, mother's employment status, number of children, the age of the youngest child, children going to nursery school or kindergarten, use of childcare services, self-evaluation of low economic status, work hours on weekdays, and marital relationship satisfaction.Results The data of 360 men were analyzed (mean age 36.8 years, standard deviation 5.6). The results of the multivariable regression analyses with interaction terms are as follows: gender role attitude was significantly associated with childcare (β=-0.103) and housework (β=-0.125); appraisal support was significantly associated with childcare (β=0.142) and housework (β=0.199); and the interaction between gender role attitude and instrumental support was significant (β=0.176), indicating that, in individuals with a high gender role attitude score, a higher level of instrumental support was related to a higher childcare score (β=0.242).Conclusions Fathers with egalitarian gender role attitudes and those who receive appraisal support from the other parent are more likely to participate in childcare. In addition, fathers with traditional gender role attitudes who receive instrumental support from the other parent may tend to participate in childcare.
