Introduction: It is common that personality disorder (PD) co-occurs with major depressive disorder (MDD).In the current literature, there is a dearth of information on the co-occurrence of PD and MDD among Chinese population.Materials and Methods: 609 individuals were randomly sampled from outpatients diagnosed as MDD in Shanghai Mental Health Center.
Co-morbidity of PDs was assessed using the Personality Diagnostic Questionnaire Fourth Edition Plus (PDQ-4+) and eligible subjects were interviewed with the Structured Clinical Interview for DSM-IV Axis II (SCID-II).The score of PDQ-4+ and the rate of SCID-II PD between subjects diagnosed with MDD and those with anxiety disorders (AD) were compared.Results: Two hundred fifty-eight outpatients (42.
36%) with MDD were recognized feline 1-hcpch vaccine to possess at least one criterion of diagnosis for PD, according to the DSM-IV.The most prevalent PD was depressive PD (14.61%), followed by avoidant (11.
49%) and borderline (11.49%) PD.Cluster C PDs (anxious and panic PD) were the most common PD types (12.
12%) when compared to other clusters.Compared to patients with AD, individuals with MDD were significantly more likely to have paranoid PD (6.6% vs.
3.3%, p = 0.011), borderline PD (11.
5% vs.3.7%, p = 0.
000), passive-aggressive PD (5.6% vs.2.
4%, p = 0.007), and depressive PD (14.6% vs.
7.8%, p = 0.000).
Discussion: The finding indicates that there is a high prevalence alphaville clothing of PD among patients with MDD.More significant co-morbidity rates of PDs in MDD have been found when compared with AD.Further studies for the longitudinal impact of the PD-MDD co-morbidity are in need.
