Abstract

Introduction

This study illustrates how mindfulness and acceptance-based intervention (MABI) can change metacognitions and executive functions among individuals with anxiety disorders.

Methods

Forty-five Iranian individuals (mean [SD] age, 24.60 [4.94] years; 51.1 % female) with comorbid anxiety disorders participated in a randomized, waitlist-controlled trial of weekly group sessions of either MABI or waitlist control (WLC). Primary and process of change outcomes were assessed at baseline, post-intervention, and 1-month follow-up.

Results

Significant changes were observed over time on anxiety symptoms (Cohen d = 1.04, 95% CI [0.40 ± 1.65]), as well as on metacognitive beliefs (Cohen d = 1.04, 95% CI [0.40 ± 1.64]), executive functions (Cohen d = 0.91, 95% CI [0.28 ± 1.51]), and mindfulness facets (Cohen d = 0.97, 95% CI [0.34 ± 1.58]), in favor of MABI over WLC.

Conclusions

Overall, findings add to the knowledge in the field and provide cross-cultural evidence in support of MABIs as interventions that target anxiety symptoms, metacognitive beliefs and executive functions in a non-Western culture.

焦虑症患者在接受正念干预期间元认知和执行功能的变化：随机等待对照试验

本研究阐述了正念和接受式干预（MABI）如何改变焦虑症患者的元认知和执行功能。45 名合并有焦虑症的伊朗人（平均 [SD] 年龄为 24.60 [4.94] 岁；51.1% 为女性）参加了每周一次的 MABI 或候补对照（WLC）小组课程的随机候补对照试验。在基线、干预后和 1 个月的随访中对主要结果和变化过程进行了评估。随着时间的推移，焦虑症状（Cohen = 1.04，95% CI [0.40±1.65]）以及元认知信念（Cohen = 1.04，95% CI [0.40±1.64]）、执行功能（Cohen = 0.91，95% CI [0.28±1.51]）和正念方面（Cohen d = 0.97，95% CI [0.34±1.58]）都发生了显著变化，MABI 比 WLC 更受青睐。总之，研究结果丰富了该领域的知识，并提供了跨文化证据，支持人机对话疗法作为针对非西方文化中焦虑症状、元认知信念和执行功能的干预措施。

期刊介绍： The Journal of Contextual Behavioral Science is the official journal of the Association for Contextual Behavioral Science (ACBS). Contextual Behavioral Science is a systematic and pragmatic approach to the understanding of behavior, the solution of human problems, and the promotion of human growth and development. Contextual Behavioral Science uses functional principles and theories to analyze and modify action embedded in its historical and situational context. The goal is to predict and influence behavior, with precision, scope, and depth, across all behavioral domains and all levels of analysis, so as to help create a behavioral science that is more adequate to the challenge of the human condition.
