Prior research on self-disclosure of sexual orientation has focused almost exclusively on the assessment of direct verbal self-declaration by gay men, lesbians and bisexual persons. The Behavioral Self-Disclosure Questionnaire (BDQ) was developed to assess behavioral language in the “being out” process. One hundred seventy-seven participants completed the BDQ, the Sexual Orientation Disclosure Scale (SODS; Shachar and Gilbert, 1983), and a modification of the SODS, entitled the Acceptance of Sexual Orientation Disclosure Scale (ASODS). Results indicated that the BDQ was comprised of six factors and the overall scale had excellent internal consistency. Pearson Product-Moment Correlations showed a significant and positive correlation between the BDQ and verbal disclosure as assessed by the SODS.
