Abstract

Understanding why interventions work is essential to optimizing them. Although mechanistic theories of meditation-based interventions (MBIs) exist, empirical evidence is limited. We randomly assigned 662 adults (79.9% reported clinical levels of anxiety or depressive symptoms) to a 4-week smartphone-based MBI or wait-list control condition early in the COVID-19 pandemic. Psychological distress and four theory-driven preregistered psychological mediators of well-being (mindful action, loneliness, cognitive defusion, and purpose) were assessed five times during the intervention period and at 3-month follow-up. In preregistered analyses, assignment to the intervention predicted significant gains on all mediators, which, in turn, significantly mediated follow-up distress (21.9%–62.5% of intervention effect on distress). No significant mediation pathway was observed in an exploratory multiple mediator analysis, but reduced loneliness accounted for 61.7% of the combined indirect effect. Multiple psychological pathways may mediate reduced distress in a digital MBI.

减轻压力的心理中介：基于智能手机的幸福感培训随机对照试验的预先登记分析

了解干预措施发挥作用的原因对于优化干预措施至关重要。虽然存在基于冥想的干预（MBI）的机理理论，但经验证据却很有限。在 COVID-19 大流行的早期，我们将 662 名成年人（79.9% 的人报告有临床水平的焦虑或抑郁症状）随机分配到为期 4 周的基于智能手机的 MBI 或等待对照组中。在干预期间和 3 个月的随访中，对心理困扰和四种理论驱动的幸福感心理中介（正念行动、孤独感、认知化解和目的）进行了五次评估。在预先登记的分析中，干预的分配预示着所有中介因子的显著提高，而这些中介因子反过来又对后续的困扰有显著的中介作用（干预对困扰影响的 21.9%-62.5% ）。在探索性的多重中介分析中，没有观察到明显的中介途径，但孤独感的减少占了综合间接效应的61.7%。在数字 MBI 中，多种心理途径都可能对减轻困扰起到中介作用。
