Effects of participation in and connectedness to the LGBT community on substance use involvement of sexual minority young people

Most participants identified as homosexual (57%, n = 726) and male (54%, n = 683). In the overall sample, participation in and connectedness the LGBT community were significantly associated with increased substance use involvement before (F(2,1263) = 35.930, p ≤ 0.001, R2 = 0.052) and after controlling for other variables (F(8,1095) = 33.538, p ≤ 0.001, R2 = 0.191), with meaningfully higher effect sizes for participation than for connectedness. After controlling for other variables, connectedness only remained significant for homosexuals. Effect sizes for participation were higher for females than males, and bisexuals than homosexuals. However, participation in the LGBT Community was not associated with substance use in participants identifying with a non-binary gender identity. In conclusion, substance use involvement was associated with participation in the LGBT community, but connectedness to the LGBT community only had a weak association with substance use involvement in the homosexual subgroup.
