This study established the validity and factor structure of the Faculty Version of the Affirmative Training Inventory (ATI‐F), which assesses faculty members’ perceptions of the level of lesbian, gay, and bisexual (LGB) affirmative training that occurs in clinical programs. Additionally, this study examined the latent associations among the subscales of the ATI‐F and three convergent validity items utilizing a sample of 117 faculty members from accredited family therapy programs. The findings provide empirical support for the relationship between including classroom content on LGB affirmative therapy and faculty members’ beliefs about LGB individuals and relationships. Specifically, faculty members who report more positive beliefs about LGB clients appear to be more likely to include LGB affirmative therapy content in the courses they teach.
