Based on the Combined Cognitive Biases Hypothesis, the current study via two parallel studies aims to explore the potential mediating role of attention biases and attention control regarding the link between trait mindfulness and psychological stress in adolescents.
For Study 1, we collected self-reported data from 2123 Chinese adolescents (mean age = 15.6 years, SD = 2.37; 52.8% female) in four schools. The participants completed measures of trait mindfulness, perceived stress, and attention bias. Mediation analysis was employed to investigate the potential mediating effect of attention bias. In Study 2, 123 participants (mean age = 17.7 years, SD = 2.68; 41.46% female) completed the attention network task after inducing attention bias. Then, trait mindfulness and perceived stress were measured. Mediation analysis was employed to investigate the potential mediating effect of attention control (alerting, orienting, and conflict monitoring) under attention bias.
Study 1 demonstrated a significant mediating effect of negative attention bias ([-0.13, -0.07], p < .05) but not positive attention bias in the relationship between trait mindfulness and psychological stress. Study 2 revealed that conflict monitoring in negative attention bias ([-0.41, -0.16], p < .05), rather than alerting and orienting in negative attention bias, showed a significant mediating effect on the association between trait mindfulness and psychological stress.
Findings from the two studies suggest that conflict monitoring during negative attention bias may be the underlying mechanism through which trait mindfulness helps mitigate psychological stress in adolescents.
基于综合认知偏差假说，本研究通过两项平行研究，旨在探讨注意力偏差和注意力控制在青少年特质正念与心理压力之间的联系中所起的潜在中介作用。
在研究1中，我们收集了来自四所学校的2123名中国青少年（平均年龄 = 15.6岁，标准差 = 2.37；52.8%为女性）的自我报告数据。参与者完成了特质正念、感知压力和注意力偏差的测量。采用中介分析来研究注意力偏差的潜在中介作用。在研究2中，123名参与者（平均年龄 = 17.7岁，标准差 = 2.68；41.46%为女性）在引发注意力偏差后完成了注意力网络任务。然后，测量特质正念和感知压力。采用中介分析来研究在注意力偏差下注意力控制（警觉、定向和冲突监测）的潜在中介作用。
研究1表明，在特质正念与心理压力的关系中，消极注意力偏差存在显著中介作用（[-0.13, -0.07]，p <.05），而积极注意力偏差不存在。研究2显示，消极注意力偏差中的冲突监测（[-0.41, -0.16]，p <.05），而非消极注意力偏差中的警觉和定向，在特质正念与心理压力的关联中显示出显著中介作用。
两项研究的结果表明，消极注意力偏差期间的冲突监测可能是特质正念帮助减轻青少年心理压力的潜在机制。
