Contextualizing gay-straight alliances: student, advisor, and structural factors related to positive youth development among members.

Gay-straight alliances (GSAs) may promote resilience. Yet, what GSA components predict well-being? Among 146 youth and advisors in 13 GSAs (58% lesbian, gay, bisexual, or questioning; 64% White; 38% received free/reduced-cost lunch), student (demographics, victimization, attendance frequency, leadership, support, control), advisor (years served, training, control), and contextual factors (overall support or advocacy, outside support for the GSA) that predicted purpose, mastery, and self-esteem were tested. In multilevel models, GSA support predicted all outcomes.
