OBJECTIVE 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. METHOD Participants were 111 youth ages 12 to 17 years old (M = 14.17, SD = 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. RESULTS The mindfulness intervention resulted in a significant reduction in stressor-reactive negative affect (t = 2.001, df = 96, p = .048; Cohen's d = .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, p = .032). CONCLUSIONS 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.

一项针对有内化问题风险的青少年的在线正念计划的随机对照试验。


目的 这项随机对照试验的目的是测试在线、指导正念干预对具有高水平特质消极情感的青少年的瞬时负面影响 （mNA） 的影响。方法 参与者是 111 名 12 至 17 岁的青少年 （M = 14.17，SD = 1.60）。青年自我认同为 68% 女性、29% 男性和 4.5% 性别多元化;54.55% 被认定为白人;31.82 人报告为西班牙裔/拉丁裔。参与者因具有高水平的特质负面影响而被选中，并被随机分配接受正念计划或不接受干预。我们使用生态瞬时评估来测量压力和情绪，并得出由压力源无关和压力源反应性负面影响组成的 mNA 测量。生态瞬时评估协议涉及参与者在 Qualtrics 上完成每日 4 次的简短调查/日记条目，持续 5 天。使用患者健康问卷 8 、广泛性焦虑症 7 和儿童焦虑相关障碍筛查评估内化症状。结果 正念干预导致压力源反应性负面影响显着减少 （t = 2.001，df = 96，p = .048;Cohen 的 d = .40），但不是不依赖压力源的 mNA 或总体 mNA。此外，应激源反应性负面影响的减少与内化症状的变化显着相关 （标准化 β = .26，p = .032）。结论 这些结果表明，在具有高水平特质消极情感的青少年中，相对实惠且可访问的数字正念计划显着降低了压力源反应性负面影响。 对压力源独立性或总体平均 mNA 没有影响表明正念对高危青少年样本中压力源反应性负面影响的影响具有一定的特异性。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
