This study investigated the effect of a mindfulness-based intervention on pathological symptoms in boys with externalised disorders. A total of 24 elementary school students with externalising disorders, diagnosed by completing the Child Behavior Checklist (CBCL), were randomly assigned to a mindfulness-based intervention for two months. One session per week was offered and each session lasted one hour (n = 12) or as a wait-list control group (n = 12). Data were analysed via a multivariate analysis of covariance (MANCOVA) test. Students from the intervention group showed greater reductions in rule-breaking behaviours than those in the wait-list control group. Also, there was clear superiority of the intervention relative to the wait-list control group for reducing both aggression and rule-breaking behaviours (effect size differences were d = −2.52 and d = −1.88 respectively). These positive results on outcome measures provide initial evidence for a mindfulness-based intervention as a treatment option for boys with externalising disorders.

本研究调查了基于正念的干预对外化障碍男孩病理症状的影响。共有 24 名通过完成儿童行为检查表 (CBCL) 诊断的外化障碍小学生被随机分配到基于正念的干预两个月。每周提供一次会议，每次会议持续一小时（n = 12）或作为候补名单对照组（n= 12)。通过多变量协方差分析 (MANCOVA) 检验分析数据。干预组的学生比等待名单对照组的学生的违规行为减少更多。此外，相对于等待名单对照组，干预在减少攻击性和违反规则行为方面具有明显优势（效果大小差异分别为d = -2.52 和d = -1.88）。这些关于结果测量的积极结果为基于正念的干预作为外化障碍男孩的治疗选择提供了初步证据。
