The following hypotheses regarding interpersonal resource exchange among (a) dating couples (
n
= 206 couples) and (b) engaged/married couples (
n
= 103 couples) were tested: (1) levels of affectionate behavior are reciprocated (i.e. paths are bidirectional) among couples; (2) levels of respectful behavior are reciprocated among couples; (3) individuals' reported affectionate and respectful behaviors are correlated positively; (4) individuals' affection-giving traits are better as positive predictors of individuals' affectionate behavior among engaged/married couples than among dating couples; (5) individuals' respect-giving traits are better as positive predictors of individuals' respectful behavior among engaged/married couples than among dating couples; (6) individuals' gender-role compliance is better as a negative predictor of individuals' affectionate behavior among dating couples than among engaged/married couples; and (7) individuals' gender-role compliance is better as a negative predictor of individuals' respectful behavior among dating couples than among engaged/married couples. Individuals' interpersonal traits and gender-role compliance were self-reported, whereas individuals' interpersonal behaviors were reported by their partners. Results supported Hypotheses 1-3 (derived from resource exchange theory proposed by Foa & Foa, 1974) but not Hypotheses 4-7 (derived from the model of levels of relational involvement proposed by Levinger & Snoek, 1972). Unexpectedly, affection-giving traits generally were positive predictors of affectionate
and
respectful behavior, whereas respect-giving traits generally did not predict affectionate
or
respectful behavior. Implications for the study of interpersonal traits, gender roles and behavioral reciprocity in heterosexual relationships are discussed.
