This study found differences between out and closeted lesbian and gay (LG) students in their perceptions of the campus climate and experiences on a Midwestern college campus. Eighty LG students responded to an 87-item survey; 44 were categorized as the "low out" (closeted) group and 36 as the "highly out" group. The study was primarily descriptive, but used independent t-tests and chi-square analyses to compare out and closeted students on core variables. Out and closeted students reported differences in the need to hide their identity, perceived unfair treatment, perceptions of an anti-LG campus, knowledge of LG issues, involvement and activity levels, and the presence of a LG student network.
