Borderline Personal Disord Emot Dysregul. 2025 Aug 28;12(1):33. doi: 10.1186/s40479-025-00310-6.
Borderline Personality Disorder (BPD) is a complex mental health condition characterized by pervasive instability in mood, interpersonal relationships, self-concepts, and behavior. A reliable assessment of BPD symptom severity is essential for effective treatment planning and evaluation. This study introduces and evaluates the Borderline Symptom List Interview (BSL-I), a semi-structured interview designed to assess the severity of BPD symptoms comprehensively.
The BSL-I is a freely accessible 31-item interview designed to assess BPD symptom severity. It evaluates (a) the frequency and subjective distress associated with BPD-specific and typical psychopathological symptoms, (b) the behavioral consequences of these symptoms, (c) functional impairment, and (d) facets of positive mental health. The items were developed through an iterative process, incorporating feedback from international experts and individuals with lived experience of BPD. Psychometric properties of the BSL-I were examined cross-sectionally in different samples of clients meeting DSM-5 criteria for BPD (n = 171), clinical controls (n = 89), and healthy controls (n = 43).
The BSL-I demonstrates good internal consistency within the BPD sample (Cronbach's α = 0.82) and good interrater reliability (ICC = 0.768). It significantly discriminates between BPD clients and clinical controls (Cohen's d = 2.02) and healthy controls (Cohen's d = 3.88). High correlations were observed with other established BPD symptom measures, including the number of IPDE criteria (r = 0.70, p < 0.001) and the BSL-23 (r = 0.83, p < 0.001).
Our findings indicate that the BSL-I is a reliable and valid multidimensional instrument for assessing the severity of BPD. Both clinical experts and clients found the application of the BSL-I acceptable and feasible. Future research might explore its sensitivity to change resulting from psychosocial treatments and assess its utility for treatment planning and outcome measurement.
The BSL-I is a practical and psychometrically sound instrument for assessing the severity of BPD symptoms in clinical and research contexts.
边缘型人格障碍（BPD）是一种复杂的心理健康状况，其特征是情绪、人际关系、自我概念和行为普遍不稳定。对BPD症状严重程度进行可靠评估对于有效的治疗计划和评估至关重要。本研究介绍并评估了边缘型症状清单访谈（BSL-I），这是一种旨在全面评估BPD症状严重程度的半结构化访谈。
BSL-I是一项可免费获取的包含31个条目的访谈，旨在评估BPD症状严重程度。它评估（a）与BPD特定和典型精神病理症状相关的频率和主观痛苦，（b）这些症状的行为后果，（c）功能损害，以及（d）积极心理健康的方面。这些条目通过反复迭代过程制定，纳入了国际专家和有BPD生活经历者的反馈。在符合DSM-5 BPD标准的不同客户样本（n = 171）、临床对照（n = 89）和健康对照（n = 43）中对BSL-I的心理测量特性进行了横断面研究。
BSL-I在BPD样本中显示出良好的内部一致性（Cronbach's α = 0.82）和良好的评分者间信度（ICC = 0.768）。它能显著区分BPD患者与临床对照（Cohen's d = 2.02）以及健康对照（Cohen's d = 3.88）。与其他既定的BPD症状测量方法有高度相关性，包括IPDE标准数量（r = 0.70，p < 0.001）和BSL-23（r = 0.83，p < 0.001）。
我们的研究结果表明，BSL-I是一种可靠且有效的多维工具，用于评估BPD的严重程度。临床专家和患者都认为BSL-I的应用是可接受且可行的。未来的研究可能会探索其对心理社会治疗引起的变化的敏感性，并评估其在治疗计划和结果测量中的效用。
BSL-I是一种实用且心理测量学上合理的工具，用于在临床和研究环境中评估BPD症状的严重程度。
