The aim of this study is to investigate Iranian psychotherapists’ behaviors and beliefs toward sexual orientation and gender identity. The sample consisted of 358 Iranian psychotherapists, of whom 29.3% were male and 67% were female. Results from the chi-square analyses showed that more male participants reported accepting homosexual clients and treating them as having a pathological disorder than their female counterparts; and licensed respondents reported engaging more in accepting only male or female clients, accepting more homosexual and transgender clients for (...) treatment, and treating them as having a pathological disorder when compared with their unlicensed counterparts. Furthermore supervised respondents reported accepting more homosexual clients than their unsupervised counterparts. However results from the multivariate analysis of variance has indicated that the female participants reported “accepting homosexuals or transgender clients for treatment” more often than the male participants; unsupervised participants reported “accepting homosexual or transgender clients for treatment” and “treating homosexuality per se as a pathological disorder” more often than their supervised counterparts.
