Abstract

Abstract: The Personality Inventory for the DSM-5 (PID-5) is an assessment instrument included with the DSM-5 's hybrid model of personality disorders. It includes 25 personality facets comprising 5 domains. This research continues validating the instrument by testing disparities between LGB and heterosexual individuals' PID-5 scores and potential diagnostic classifications. Because no other DSM editions have included LGB personality disorder prevalence rates, this research also addresses a gap in the literature by including early epidemiological data using the new hybrid model. This study included US women and men ( N = 1024; 533 females) who were recruited online. Lesbians and bisexual women and men had greater scores on several PID-5 domains and facets relative to heterosexual peers. Additionally, using t -scores normed with a national sample, lesbians and bisexual individuals were classified into personality disorder diagnostic categories more often than heterosexual counterparts. This disparity was especially pronounced in bisexual women, who had significantly greater prevalence rates than heterosexual women in 7 of 10 diagnostic categories. Unexpectedly, gay men had scores similar to those of heterosexual men. These findings are a necessary first step in establishing personality disorder prevalence rates for LGB people, and they demonstrate the need for personality disorder research in LGB populations. Highlights: Investigation of disparities between LGB and heterosexual people's PID-5 scores Lesbian and bisexual men and women had inflated PID-5 facet and domain scores. LGB people categorized into potential diagnostic categories more than non-LGB peers. Bisexual women's prevalence rates significantly greater than others on 7 of 10 PDs.
