The purpose of this randomized controlled trial was to test the effects of an online, coached mindfulness intervention on momentary negative affect (mNA) for youth with high levels of trait negative affectivity.
Participants were 111 youth ages 12 to 17 years old ( = 14.17, = 1.60). Youth self-identified as 68% female, 29% male, and 4.5% gender diverse; 54.55% identified as White; 31.82 reported being Hispanic/Latinx. Participants were selected for having high levels of trait negative affect and were randomized to receive either the mindfulness program or no intervention. We used ecological momentary assessment to measure stress and emotions and to derive measures of mNA comprised of stressor-independent and stressor-reactive negative affect. The ecological momentary assessment protocol involved participants completing a short survey/diary entry on Qualtrics four times per day for 5 days. Internalizing symptoms were assessed with the Patient Health Questionnaire-8, Generalized Anxiety Disorder-7, and the Screen for Child Anxiety Related Disorders.
The mindfulness intervention resulted in a significant reduction in stressor-reactive negative affect ( = 2.001, = 96, = .048; Cohen's = .40), but not stressor-independent mNA or overall mNA. Additionally, reductions in stressor-reactive negative affect significantly correlated with changes in internalizing symptomatology (standardized β = .26, = .032).
These results indicate that among youth with high levels of trait negative affectivity, a relatively affordable and accessible digital mindfulness program significantly reduced stressor-reactive negative affect. The absence of an effect on stressor-independent or overall average mNA suggests some specificity of the effects of mindfulness to stressor-reactive negative affect in an at-risk sample of adolescents.

本随机对照试验旨在检验在线指导的正念干预对特质消极情感水平较高的青少年的瞬时消极情绪（mNA）的影响。
参与者为111名12至17岁的青少年（平均年龄 = 14.17岁，标准差 = 1.60）。青少年自我认定为68%为女性，29%为男性，4.5%为性别多样化；54.55%认定为白人；31.82%报告为西班牙裔/拉丁裔。参与者因特质消极情感水平较高而被选中，并被随机分配接受正念项目或不接受干预。我们使用生态瞬时评估来测量压力和情绪，并得出由与压力源无关和对压力源有反应的消极情绪组成的mNA测量值。生态瞬时评估方案要求参与者在5天内每天在Qualtrics上完成4次简短的调查/日记记录。使用患者健康问卷-8、广泛性焦虑障碍-7和儿童焦虑相关障碍筛查量表评估内化症状。
正念干预使对压力源有反应的消极情绪显著降低（F = 2.001，自由度 = 96，p = .048；科恩d = .40），但对与压力源无关的mNA或总体mNA没有影响。此外，对压力源有反应的消极情绪的降低与内化症状的变化显著相关（标准化β = .26，p = .032）。
这些结果表明，在特质消极情感水平较高的青少年中，一个相对经济实惠且易于获得的数字正念项目显著降低了对压力源有反应的消极情绪。对与压力源无关或总体平均mNA没有影响，这表明在处于风险中的青少年样本中，正念对压力源有反应的消极情绪的影响具有一定的特异性。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
