The current study aimed to examine the influence of intolerance of uncertainty (IU) on emotional disturbance through coping. Further, the buffering effect of mindfulness on the relationship between IU and emotional disturbance was explored. Data were collected through online survey method, and mediation and moderation analyses were performed. Study 1 examined how different sets of coping responses mediated the relationship between IU and emotional disturbance. Study 2 replicated the analysis performed in study 1 and further examined the moderating effect of mindfulness on the association between IU and coping/emotion disturbance. Results showed that IU led to an increased use of maladaptive coping responses, a decreased use of a subset of adaptive coping responses, and an increased use of support seeking responses. The former two exacerbated emotional disturbance, while support seeking ameliorated emotional problems. The current study did not find significant moderating effect of mindfulness on the relationship between IU and coping. Mindfulness moderated the direct effect of IU on emotional disturbance: as the level of mindfulness increased, the magnitude of the effect of IU on emotional disturbance decreased. The current study shed light on the mechanisms underlying the association between IU and emotional disturbance. Further, the protective effect of mindfulness was established, which may enlighten the development of interventions targeting IU.

为了澄清不确定性不耐受通过影响应对反应, 进而影响情绪问题的作用路径, 探索正念所起到的保护性作用, 采用网络问卷调查法回收数据, 并对有效数据进行中介和调节分析。研究1考察不同的应对反应在不确定性不耐受与情绪问题之间的中介作用。研究2重复研究1 的中介分析, 并在此基础上考察正念对不确定性不耐受与应对/情绪问题之间关系的调节作用。研究结果表明, 不确定性不耐受会增加非适应性的应对反应, 减少一部分适应性应对反应, 增加寻求支持的应对反应; 前两者会进一步加剧情绪问题, 而寻求支持会缓解情绪问题。研究中未发现正念在不确定性不耐受与应对之间的调节作用。正念会调节不确定性不耐受对情绪问题的直接作用, 正念水平越高, 不确定性不耐受引发的情绪问题越少。研究结果澄清了不确定性不耐受影响情绪问题的机制, 并验证了正念的保护性作用, 为针对不确定性不耐受的临床干预提供思路。
