Abstract

Intolerance of uncertainty (IU) is the tendency to react negatively on affective, cognitive and behavioural levels to uncertain situations and to harbour negative beliefs about the implications of uncertainty. IU has been linked to psychopathology and shown to impact treatment outcomes. This study systematically reviewed the literature and performed a meta-analysis of the effects of psychotherapy on IU. A total of 22 studies (1491 participants) were identified in online searches and included in the meta-analyses. Analyses were performed on studies with passive and active control conditions. The pooled effect on IU from studies with passive control was large (g = −0.94 [95% CI −1.25 to −0.62]) but with significant heterogeneity. Pooled effects on IU from studies with active controls were not significant. Moderator analysis showed that among studies with a passive control condition, studies that recruited participants from clinical care facilities produced smaller effect sizes. Among studies with an active control condition, study quality significantly moderated the results, with higher quality leading to a larger effect size. These results indicate that changes in IU may be difficult to reliably achieve in psychotherapy and leave many questions about the effect of psychotherapy on IU unanswered, such as what active components produced the observed changes in studies with passive control.

心理疗法对不确定性耐受性的影响：系统回顾与元分析》。

对不确定性的不容忍（IU）是指在情感、认知和行为层面上对不确定情况做出消极反应的倾向，以及对不确定性的影响持有消极信念的倾向。IU 与精神病理学有关，并被证明会影响治疗效果。本研究系统地回顾了相关文献，并对心理疗法对 IU 的影响进行了荟萃分析。在线搜索共发现了 22 项研究（1491 名参与者），并将其纳入了荟萃分析。分析针对被动和主动对照条件的研究。被动控制研究对 IU 的总体影响较大（g = -0.94 [95% CI -1.25 to -0.62]），但存在显著的异质性。主动控制研究对 IU 的总体影响不显著。主持人分析表明，在采用被动对照条件的研究中，从临床护理机构招募参与者的研究产生的效应大小较小。在有主动对照条件的研究中，研究质量对结果有显著的调节作用，质量越高，效应大小越大。这些结果表明，在心理治疗中可能很难可靠地实现IU的变化，而且关于心理治疗对IU的影响还有很多问题没有得到解答，例如在被动对照的研究中，是哪些主动成分产生了所观察到的变化。

期刊介绍： Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
