Diagnosis of co-occurring personality disorders, particularly the most comorbid cluster B personality disorders in psychiatric patients is clinically important because of their association with the duration, recurrence, and outcome of the comorbid disorders. The study aimed to assess the prevalence of cluster B personality disorders and associated factors among psychiatric outpatients in Jimma Medical Center.
An institution-based cross-sectional study was conducted among 404 patients with mental illnesses at Jimma Medical Center from July 15 to September 14, 2021. A systematic random sampling method was used to recruit the participants. Personality disorder questionnaire four (PDQ-4) was used to assess the prevalence of cluster B personality disorders through a face-to-face interview. Data were entered into Epi Data Version 4.6 and exported to SPSS Version 26 for analysis. Logistic regression analysis was done and variables with a p-value less than 0.05 with a 95% confidence interval in the final fitting model were declared as independent predictors of cluster B personality disorders.
Amongst 401 respondents with response rate of 99.3%, slightly less than one-fourth (23.19%, N = 93) were found to have cluster B personality disorders. Unable to read and write(AOR = 3.28, 95%CI = 1.43-7.51), unemployment(AOR = 2.32, 95%CI = 1.19-4.49), diagnosis of depressive (AOR = 3.72, 95%CI = 1.52-9.10) and bipolar-I disorders (AOR = 2.94, 95%CI = 1.37-6.29), longer duration of illness (AOR = 2.44, 95%CI = 1.33-4.47), multiple relapses (AOR = 2.21, 95%CI = 1.18-4.15)), history of family mental illnesses (AOR = 2.05, 95%CI = 1.17-3.62), recent cannabis use (AOR = 4.38, 95%CI = 1.61-11.95), recent use of alcohol (AOR = 2.86, 95%CI = 1.34-6.10), starting to use substance at earlier age (AOR = 4.42, 95%CI = 1.51 -12.96), and suicidal attempt (AOR = 2.24, 95%CI = 1.01-4.96), were the factors significantly associated with cluster B personality disorders.
The prevalence of cluster B personality disorders was high among mentally ill outpatients and found to be important for mental health professionals working in the outpatient departments to screen for cluster B personality disorders as part of their routine activities, particularly those who have mood disorders, longer duration of illness, multiple relapses, history of family mental illnesses, suicidal attempt and are a current user of alcohol and cannabis.
在精神科患者中，同时诊断出共病人格障碍，特别是最常见的 B 群人格障碍，具有临床重要性，因为它们与共病障碍的持续时间、复发和结果有关。本研究旨在评估 Jimma 医疗中心精神科门诊患者中 B 群人格障碍的患病率和相关因素。
这是一项在 2021 年 7 月 15 日至 9 月 14 日期间在 Jimma 医疗中心的 404 名精神疾病患者中进行的基于机构的横断面研究。采用系统随机抽样方法招募参与者。通过面对面访谈使用人格障碍问卷四（PDQ-4）评估 B 群人格障碍的患病率。数据录入 Epi Data 版本 4.6 并导出到 SPSS 版本 26 进行分析。采用逻辑回归分析，最终拟合模型中 p 值小于 0.05 且 95%置信区间的变量被宣布为 B 群人格障碍的独立预测因子。
在 401 名有应答者中（应答率为 99.3%），发现略低于四分之一（23.19%，N=93）的人患有 B 群人格障碍。无法读写（AOR=3.28，95%CI=1.43-7.51）、失业（AOR=2.32，95%CI=1.19-4.49）、抑郁（AOR=3.72，95%CI=1.52-9.10）和双相 I 障碍（AOR=2.94，95%CI=1.37-6.29）的诊断、较长的病程（AOR=2.44，95%CI=1.33-4.47）、多次复发（AOR=2.21，95%CI=1.18-4.15）、有家族精神病史（AOR=2.05，95%CI=1.17-3.62）、近期使用大麻（AOR=4.38，95%CI=1.61-11.95）、近期使用酒精（AOR=2.86，95%CI=1.34-6.10）、早期开始使用物质（AOR=4.42，95%CI=1.51-12.96）和自杀企图（AOR=2.24，95%CI=1.01-4.96），这些因素与 B 群人格障碍显著相关。
精神科门诊患者中 B 群人格障碍的患病率较高，这对于在门诊工作的精神卫生专业人员来说是重要的，他们需要作为常规活动的一部分筛查 B 群人格障碍，特别是那些患有心境障碍、病程较长、多次复发、有家族精神病史、自杀企图和目前使用酒精和大麻的患者。
