This article critiques a study by Herrell Goldberg. Goldberg’s study assessed suicidal ideation, history of ever attempting suicide, & psychopathology in male twins who had sex with other men after age 18 years of age & their heterosexual co-twins. The article also critiques Goldberg’s findings that homosexual men’s increased lifetime risk of suicidal behaviors is unlikely to be owing to psychiatric comorbidity. The article critiques Goldbergs study by offering possible lurking variables, which would invalidate Goldbergs findings. (22 refs.) (AK)
