A research study was conducted (1) to investigate the effects of sex and gender of discloser, and sex of the interaction partner on self-disclosure reports and behaviors, in particular the dimensions of intimacy and control; and (2) to investigate the relationships between self-report and behavioral measures of disclosure and the impact of sex and gender on those relationships. Participants included 102 males and 194 females in a basic interpersonal communication course at a large eastern university. Participants were asked to complete the Bem Sex Role Inventory, a 21-item self-disclosure questionnaire, and the control subscale of the Wheeless disclosure measure, and participated in an acquaintance exercise. Data produced a significant sex by sex of partner interaction effect for intimacy. Results were consistent with previous research indicating more reported disclosure to same-sex than to opposite-sex targets. In the behavioral study, females disclosed more intimately than males. There were no significant results for self-report and behavioral control of intimacy. Correlations between self-report and behavioral measures for the total sample were not significant, but sex and gender of respondent affected those relationships, particularly for the intimacy dimension.
