Sociological and psychological predictors of STD infection in homosexual men: a study of four countries.

I investigated over 600 homosexual men in four countries (Sweden, Finland, Ireland, and Australia) regarding the number of times they had contracted a sexually transmitted disease (STD) and several psychological variables including masculinity and feminity, sex role conservatism, relationships with parents, number of sexual partners, attitudes towards homosexuality, and involvement in the homosexual subculture. Using multiple linear regression in each country, it was found that 19-42% of the variance of number of times infected could be accounted for by psychosocial factors, seven of which were common to all countries. The number of sexual partners was not a significant variable in any country. These data strongly suggest that numbers of infections in homosexual men are best predicted by psychological factors, and this has considerable implications for preventative and treatment programmes for homosexuals.
