Development and Validation of Two Abbreviated Intraminority Gay Community Stress Scales.

Social stressors stemming from within the gay community might render gay and bisexual men vulnerable to mental health problems. The 20-item intraminority Gay Community Stress Scale (GCSS) is a reliable measure of gay community stress, but the scale's length limits its widespread use in sexual minority mental health research. Using three independent samples of gay and bisexual men, the present research developed two abbreviated versions of the GCSS using nonparametric item response modeling and validated them. Results indicated that eight items provided maximal information about the gay community stress construct; these items were selected to form the eight-item GCSS. The eight-item GCSS reproduced the factor structure of the parent scale, and gay community stress scores obtained from it correlated with other identity-specific social stress constructs and mental health symptoms. Associations between gay community stress and mental health symptoms remained significant even after controlling for related identity-specific stressors, general life stress, and relevant demographics. A four-item version was also developed and assessed, showing good structural, convergent, criterion, and incremental validity and adequate reliability. The eight- and four-item versions of the GCSS offer efficient measures of gay community stress, an increasingly recognized source of stress for gay and bisexual men.
