This study extended the investigation of gender differences in two communication variables, self-disclosure and communication apprehension, by shifting the conceptual focus from the biological sex dichotomy to the more discriminating psychological sex-role designations: masculine, feminine, and androgynous. Using the Bern Sex-Role Inventory (BSRI) as a measure of psychological sex type, the study showed that psychological sex type is superior to biological sex categories in identifying patterns of self-reported self-disclosure and communication apprehension. A number of hypotheses were considered with regard to total disclosure to same-sex friend or opposite-sex friend, and communication apprehension.
