Sleep problems often accompany ADHD and negatively affect ADHD symptoms, however, there are not enough intervention studies on sleep interventions in children with ADHD. The present study investigated the effects of sleep hygiene training (SH) and progressive muscle relaxation exercises (PMR) in children with ADHD. Method: 57 children aged 6–12 years with ADHD were randomly assigned to the SH and SH + PMR groups and completed the intervention consisting of group training and eight weeks of telephone interviews. The effects of both intervenitons were evaluated via parent, child and clinician report scales and neuropsychological tests. Results: Both interventions resulted in significant positive changes in child sleep, ADHD symptoms, functioning, neuropsychological tests and parental sleep quality. Significant differences were found between the interventions in selective attention, peer problems and anxiety scores in favor of the SH + PMR group. Conclusion: SH may have positive effects on various clinical parameters as well as sleep problems in children with ADHD. Addition of PMR to SH may lead to further improvements in anxiety, peer problems and selective attention. SH and PMR may be a useful tool in the clinical management of children with ADHD with sleep problems.

睡眠卫生训练和渐进式肌肉放松训练对多动症儿童效果的随机对照试验

睡眠问题往往伴随着多动症，并对多动症症状产生负面影响，然而，针对多动症儿童的睡眠干预研究还不够。本研究调查了睡眠卫生训练（SH）和渐进式肌肉放松练习（PMR）对多动症儿童的影响。方法：57 名 6-12 岁 ADHD 儿童被随机分配到 SH 组和 SH + PMR 组，并完成由小组训练和八周的电话访谈组成的干预。通过家长、儿童和临床医生报告量表和神经心理学测试来评估两种干预措施的效果。结果：两种干预措施都对儿童睡眠、多动症症状、功能、神经心理学测试和父母睡眠质量产生了显着的积极变化。在选择性注意、同伴问题和焦虑评分方面的干预措施之间发现显着差异，有利于 SH + PMR 组。结论：SH 可能对 ADHD 儿童的各种临床参数以及睡眠问题产生积极影响。在 SH 中添加 PMR 可能会进一步改善焦虑、同伴问题和选择性注意力。 SH 和 PMR 可能是临床管理患有睡眠问题的 ADHD 儿童的有用工具。
