The study examined whether the Power Interaction Model is applicable for explaining the choice of power tactics in conflict situations among Israeli married couples. In addition, gender role ideology was tested as a moderator of the relationship between power usage and marital satisfaction. Seventy-eight couples reported on self usage and spouse's usage of power tactic behaviors during conflicts and completed questionnaires assessing marital satisfaction, gender role ideology (traditional, liberal) and demographics. Findings indicated greater agreement within couples for harsh rather than for soft tactic preference. As expected, preference for harsh tactics was associated with lower marital satisfaction yet gender role ideology moderated this association. The role of conflict and power usage in traditional and liberal families was addressed.
