In this study, differences in gender role ideology among middle-aged husbands (n = 126) and wives (n = 126) in Israel were examined. In addition, the contribution of several sets of variables were tested to predict gender role ideology. The sets of variables were background variables (personal background, education/employment, family variables), personality traits (self-esteem, tolerance for ambiguity), spouse's gender role ideology, and life satisfaction. The findings indicate that husbands have more traditional gender role ideology than their wives, even though the correlations between spouses were moderate and significant. In addition, the variables were found to contribute more significantly to predicting the gender role ideology of wives than of husbands. For both partners, self-esteem was the most significant predictor. Moreover, one partner's gender role ideology was found to affect the other partner's ideology. Education/employment and some personal background variables were significant predictors of wives' gender role ideology, whereas life satisfaction predicted gender role ideology only for husbands.
