We aimed to determine the prevalence of borderline personality disorder (BPD) symptoms in a sample of eating disorder (ED) outpatients and assess how BPD symptoms correlate with severity, distress, and function. A total of 119 individuals were assessed and divided into high BPD symptoms (H-BPD) and low BPD symptoms (L-BPD) using a cut-off score of seven on the McLean Screening for Borderline Personality Disorder (MSI-BPD). Groups were compared on ED diagnosis, age at ED onset, age at assessment, illness duration, body mass index (BMI), ED symptomatology, psychological distress, and psychosocial function. Correlation analyses were performed to assess the relationship between BPD symptoms and these variables. The 45.4% of the participants scored ≥7 on the MSI-BPD, indicating a diagnosis of BPD. There were no differences between the H-BPD (N = 54) and L-BPD (N = 65) groups on age at onset, age at assessment, duration of illness, BMI, or proportion of ED diagnosis. The H-BPD group reported significantly higher ED symptomatology, psychological distress, and poorer psychosocial functioning. MSI-BPD scores were positively associated with these variables. This study suggests a high prevalence of BPD symptoms within outpatients seeking ED treatment, and use of a brief screening instrument for BPD in this group may contribute to a greater understanding of the patient.

进食障碍患者的边缘型人格障碍症状：与严重程度、心理困扰和社会心理功能的关联

我们的目的是确定饮食失调 (ED) 门诊患者样本中边缘性人格障碍 (BPD) 症状的患病率，并评估 BPD 症状与严重程度、痛苦和功能的相关性。共有 119 人接受了评估，并使用 McLean 边缘性人格障碍筛查 (MSI-BPD) 的截止分数 7 分为高 BPD 症状 (H-BPD) 和低 BPD 症状 (L-BPD)。比较各组的 ED 诊断、ED 发病年龄、评估年龄、病程、体重指数 (BMI)、ED 症状、心理困扰和社会心理功能。进行相关分析以评估 BPD 症状与这些变量之间的关系。45.4% 的参与者在 MSI-BPD 上得分≥7，表明诊断为 BPD。H-BPD之间没有差异（N  = 54) 和 L-BPD ( N  = 65) 按发病年龄、评估年龄、病程、BMI 或 ED 诊断比例​​分组。H-BPD 组报告了明显更高的 ED 症状、心理困扰和更差的社会心理功能。MSI-BPD 分数与这些变量呈正相关。这项研究表明，在寻求 ED 治疗的门诊患者中，BPD 症状的患病率很高，并且在该组中使用 BPD 的简短筛查工具可能有助于更好地了解患者。
