| Abstract: | This research examined the extent that resource theory, sex-role orientation, least interested partner hypothesis, and involvement apply to cohabiting heterosexual, gay, and lesbian couples. Findings revealed that (a) resources significantly affected only married partners' relative influence and strategy usage; (b) sex-role orientation significantly affected relative influence for married partners and strategy selection for partners in both types of heterosexual couples; (c) least interest significantly affected relative influence for partners in both types of heterosexual couples and influence strategy selection for cohabi-tors; and (d) involvement significantly affected relative influence and strategy usage for all couple types. Overall, the effect of the antecedents on relative influence and strategy usage depends on the extent that partners within any couple type are similar on various antecedents. |
