Abstract

Introduction

Avoidant personality disorder (AvPD) is a prevalent condition characterized by low self-esteem and social withdrawal. Nonetheless, targeted psychotherapy remains limited. This study aimed to examine short-term metacognitive interpersonal therapy in group (MIT-G) tailored for AvPD and to compare the outcomes of patients receiving this treatment with patients participating in outpatient group therapies within specialized mental health services for personality disorders (representing best available practice).

Methods

The study had a quasi-experimental design and included 56 patients with AvPD who participated in MIT-G. The comparison group was derived from the Norwegian Network for Personality Disorders (N = 154). Assessments for the MIT-G group were conducted before and after treatment and at a 6-month follow-up. Outcome measures included personality functioning, alexithymia, symptoms of anxiety and depression, work/social functioning and group relationships.

Results

Significant, moderate improvements were found across all outcome measures in the MIT-G group. Enhancement in personality functioning was greater, and group relationships, specifically regarding group cohesion and perceptions of positive work, were rated more satisfactory than in the comparison group.

Conclusions

The findings suggest that MIT-G contributes to significant clinical improvements among patients with AvPD. The greater enhancement of personality functioning may link to better group relationships. Limitations include the nonrandomised design, unable to draw causal inferences.

回避型人格障碍的元认知人际治疗——与最佳实践的比较。

回避型人格障碍（AvPD）是一种以低自尊和社会退缩为特征的普遍疾病。尽管如此，有针对性的心理治疗仍然有限。本研究旨在检验为AvPD量身定制的短期元认知人际治疗（MIT-G），并比较接受这种治疗的患者与在专门的人格障碍心理健康服务中参加门诊团体治疗的患者的结果（代表最佳可用实践）。方法：采用准实验设计，纳入56例参加MIT-G的AvPD患者。对照组来自挪威人格障碍网络（N = 154）。在治疗前后和6个月的随访中对MIT-G组进行评估。结果测量包括人格功能、述情障碍、焦虑和抑郁症状、工作/社会功能和群体关系。结果：在MIT-G组的所有结果测量中都发现了显著的、中度的改善。人格功能的增强更大，群体关系，特别是关于群体凝聚力和积极工作的看法，被评为比对照组更令人满意。结论：研究结果表明MIT-G有助于AvPD患者的临床改善。人格功能的增强可能与更好的群体关系有关。局限性包括非随机设计，无法得出因果推论。
