This research aims to propose a gender role conflict model of GBKP (Protestant Batak Karo Church, Indonesia) pastors’ husbands with masculine ideology, marital adjustment, and self-esteem as mediators, using SEM-PLS (Structural Equation Model-Partial Least Squares). In order to measure gender-role conflict, the four-point gender-role conflict scale developed was used. The Male Role Norms Scale (MRNS) was used to measure masculine ideology, the Dyadic Adjustment Scale (DAS) was used to measure marital adjustment and The Rosenberg Self-Esteem Scale (RSE) was used to measure self-esteem. The subjects of this research were 79 pastors’ husbands at Batak Karo Protestant Church. From the five proposed hypotheses, two were accepted and three were rejected. The two accepted hypotheses were the... effect of masculine ideology towards gender-role conflict and the effect of marital adjustment towards gender-role conflict. Meanwhile, the hypotheses of the effects of both masculine ideology and marital adjustment towards self-esteem, as well as the effect of self-esteem towards gender-role conflict were rejected.
