title: Prevalence of borderline personality disorder and its clinical correlates in Chinese patients with recent deliberate self-harm.
abstract: This study examined the point prevalence of Borderline Personality Disorder (BPD) and its clinical correlates in patients with recent deliberate self-harm (DSH) in Hong Kong. A representative consecutive sample (n = 160) of patients with DSH referred to Prince of Wales Hospital from April 1, 2007 to March 31, 2008 was recruited. Their BPD status was determined according to the BPD subscale of the Chinese version of Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). The point prevalence of BPD was calculated. Subjects with and without BPD were compared in terms of demographic and clinical characteristics. Thirty out of 160 (18.8%) DSH patients were found to suffer from BPD. DSH patients with BPD were more likely to be female (p = .020), more often reported history of childhood physical (p = 0.043) and sexual abuse (p < 0.001), history of past DSH (p = 0.010), being younger at first DSH (p = 0.039), and more likely to suffer from current alcohol and substance use disorder (p = 0.043) and eating disorder (p = 0.040) than those without BPD. Being female, having history of childhood sexual abuse and current alcohol and substance use disorder were found to be independent predictors of BPD status by binary logistic regression.
