Personality disorders: community prevalence and socio-demographic correlates

Multiple studies have reported community prevalence rates of personality disorders (PDs), but these studies differed in terms of diagnostic criteria, assessment instruments, communities sampled, and size, producing widely ranging estimates. We take a meta-analytic approach to characterizing PD community prevalence rates by comparing results from two reviews that pooled previous studies. Overall, particular PD rates are low in community samples, but the presence of any PD is relatively high, with approximately one person in seven experiencing personality psychopathology. High congruence of prevalence estimates, but low rank-order agreement of rates, was observed. We discuss how the presence of PD is associated with socio-demographic correlates such as gender, race/ethnicity, and age and highlight areas for further study.
