Abstract

Dialectical Behaviour Therapy (DBT) is an evidence-based treatment for borderline personality disorder (BPD), with findings demonstrating improvements in various BPD features and related behaviours, such as nonsuicidal self-injury (NSSI). Theory and research suggest that reductions in emotion dysregulation and interpersonal dysfunction could account for at least some of the reduction in NSSI observed during the course of DBT. The current research investigated: 1) the trajectory of changes in emotion dysregulation, interpersonal dysfunction, and NSSI over the course of DBT, and 2) whether changes in emotion dysregulation mediate the relationship between changes in interpersonal dysfunction and changes in NSSI over treatment. One hundred and twenty individuals with BPD enrolled in a multi-site randomized-clinical trial were assessed at five timepoints over 12 months of standard DBT. Results indicated that interpersonal dysfunction and NSSI decreased over the course of DBT. Emotion dysregulation decreased in a quadratic manner such that most of the gains in emotion dysregulation occurred in earlier phases of DBT. Although changes in interpersonal dysfunction predicted changes in emotion dysregulation, changes in emotion dysregulation did not mediate the relationship between changes in interpersonal dysfunction and changes in NSSI.

在针对边缘型人格障碍的辩证行为疗法中，情绪失调和人际交往障碍在非自杀性自伤中的作用。

辩证行为疗法（DBT）是治疗边缘型人格障碍（BPD）的一种循证疗法，研究结果表明，该疗法改善了边缘型人格障碍的各种特征和相关行为，如非自杀性自伤（NSSI）。理论和研究表明，情绪失调和人际交往障碍的减少至少可以解释 DBT 治疗过程中观察到的 NSSI 减少的部分原因。目前的研究调查了1）在 DBT 治疗过程中，情绪失调、人际功能障碍和 NSSI 的变化轨迹；2）情绪失调的变化是否介导了治疗过程中人际功能障碍变化和 NSSI 变化之间的关系。在为期 12 个月的标准 DBT 治疗过程中，对参加多地点随机临床试验的 120 名 BPD 患者在五个时间点进行了评估。结果表明，在 DBT 治疗过程中，人际交往障碍和 NSSI 有所减少。情绪失调以二次方的方式下降，因此情绪失调的大部分改善发生在 DBT 的早期阶段。虽然人际交往障碍的变化预示着情绪失调的变化，但情绪失调的变化并不介导人际交往障碍的变化与 NSSI 变化之间的关系。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
