Abstract: | Brother-sister relationships are understudied within the field of personal relationships. Accordingly, the present study examines patterns of interpersonal resource exchange (drawing upon resource exchange theory; Foa & Foa, 1974), along with influences of gender-related personality traits (i.e., agency and communion) on individuals’giving of interpersonal resources (i.e., affection and respect), among 79 brother-sister pairs. Consistent with predictions, brothers’and sisters’exchanges of both affection and respect were positive and significant. Also, consistent with predictions, communion was a positive and significant predictor of respectful behavior among sisters. However, contrary to hypotheses, communion did not achieve or approach significance as a predictor of respectful behavior among brothers, nor did communion achieve or approach significance as a predictor of affectionate behavior among sisters or brothers Implications for the study of male-female relationships in general—and brother-sister relationships in particular—are discussed. |
