The aim of this study was to compare the prevalence of Personality Disorders assessed by Structured Clinical Interview for Axis-II in 155 inpatients diagnosed with Unipolar Disorder vs inpatients with Bipolar Disorder (39). The most frequent Axis II diagnoses among Unipolar inpatients were Borderline (31.6%), Dependent (25.2%), and Obsessive-Compulsive (14.2%) Personality Disorders. Among Bipolar inpatients, the most prevalent personality disorders were Borderline (41%), Narcissistic (20.5%), Dependent (12.8%), and Histrionic disorders (10.3%). Using chi squared analysis, few differences in distribution emerged between the two groups: Unipolar patients had more recurrent Obsessive-Compulsive Personality Disorder than Bipolar patients (chi(1)2=6.24, p<.005). Comorbid Narcissistic Personality Disorder was significantly more frequent in the Bipolar than in the Unipolar group (chi(1)2=6.34, P<.01). Considering the three clusters (DSM-IV classification), there was a significant difference between the groups, Cluster C (fearful, avoidant) diagnoses being more frequent in the Unipolar than in the Bipolar group (48.4% vs 20.5%, respectively). Cluster B (dramatic, emotionally erratic) diagnoses were found more frequently in patients with Bipolar Disorders (71.8% vs 45.2% in Unipolar patients, chi(2)2=10.1, p<.006). The differences in the distribution and prevalence of Personality Disorders between the two patient groups are discussed.
本研究的目的是比较155例被诊断为单相障碍的住院患者与双相障碍住院患者（39例）通过轴II型障碍的结构化临床访谈评估的人格障碍患病率。单相障碍住院患者中最常见的轴II型诊断是边缘型人格障碍（31.6%）、依赖型人格障碍（25.2%）和强迫型人格障碍（14.2%）。在双相障碍住院患者中，最普遍的人格障碍是边缘型人格障碍（41%）、自恋型人格障碍（20.5%）、依赖型人格障碍（12.8%）和表演型障碍（10.3%）。使用卡方分析，两组之间在分布上几乎没有差异：单相障碍患者比双相障碍患者有更多复发性强迫型人格障碍（卡方(1)2=6.24，p<0.005）。双相障碍组中共病自恋型人格障碍的发生率显著高于单相障碍组（卡方(1)2=6.34，P<0.01）。考虑到三个簇（DSM-IV分类），两组之间存在显著差异，C簇（恐惧、回避型）诊断在单相障碍组中比双相障碍组更常见（分别为48.4%和20.5%）。B簇（戏剧性、情绪不稳定型）诊断在双相障碍患者中更常见（双相障碍患者中为71.8%，单相障碍患者中为45.2%，卡方(2)2=10.1，p<0.006）。讨论了两组患者人格障碍在分布和患病率上的差异。
