We refined and replicated an efficacious brief intervention to reduce internalized homonegativity (IH) with a sample of gay and exclusively same-sex attracted men recruited from outside of LGBT community networks using Amazon Mechanical Turk. We sought to 1) determine if levels of IH differed between the original study's community-based sample and our non-community-based sample, 2) examine the efficacy of the replicated intervention, and 3) assess for longitudinal effects of the intervention at a 30-day follow-up. Four hundred eighty-four participants completed either the intervention or a stress management control condition. Mean levels of IH were higher in the current sample compared with the earlier study's community sample. The intervention was efficacious at reducing global IH, reducing personal homonegativity, and increasing gay affirmation. Ninety-six participants completed the follow-up; follow-up results were not significant and may have been affected by high rates of attrition. Implications for research and practice are discussed.
