Abstract：
UNASSIGNED: To study the effects of playing mother\'s recorded voice to preterm infants in the NICU on their mothers\' mental health as measured by the Depression, Anxiety and Stress Scale -21 (DASS-21) questionnaire.
UNASSIGNED: This was a pilot single center prospective randomized controlled trial done at a level IV NICU. The trial was registered at clinicaltrials.gov (NCT04559620). Inclusion criteria were mothers of preterm infants with gestational ages between 26wks and 30 weeks. DASS-21 questionnaire was administered to all the enrolled mothers in the first week after birth followed by recording of their voice by the music therapists. In the interventional group, recorded maternal voice was played into the infant incubator between 15 and 21 days of life. A second DASS-21 was administered between 21 and 23 days of life. The Wilcoxon rank-sum test was used to compare DASS-21 scores between the two groups and Wilcoxon signed-rank test was used to compare the pre- and post-intervention DASS-21 scores.
UNASSIGNED: Forty eligible mothers were randomized: 20 to the intervention group and 20 to the control group. The baseline maternal and neonatal characteristics were similar between the two groups. There was no significant difference in the DASS-21 scores between the two groups at baseline or after the study intervention. There was no difference in the pre- and post-interventional DASS-21 scores or its individual components in the experimental group. There was a significant decrease in the total DASS-21 score and the anxiety component of DASS-21 between weeks 1 and 4 in the control group.
UNASSIGNED: In this pilot randomized control study, recorded maternal voice played into preterm infant\'s incubator did not have any effect on maternal mental health as measured by the DASS-21 questionnaire. Data obtained in this pilot study are useful in future RCTs (Randomized Controlled Trial) to address this important issue.

摘要：
■为了研究在NICU中播放母亲录制的声音对早产儿母亲心理健康的影响，焦虑和压力量表-21(DASS-21)问卷。
■这是一项在IV级NICU进行的单中心前瞻性随机对照试验。该试验在clinicaltrials.gov（NCT04559620）注册。纳入标准是胎龄在26周至30周之间的早产儿的母亲。在出生后的第一周，对所有登记的母亲进行了DASS-21问卷调查，然后由音乐治疗师记录他们的声音。在介入组中，在生命的15到21天之间，将记录的母亲声音播放到婴儿孵化器中。在生命的21至23天之间施用第二DASS-21。使用Wilcoxon秩和检验比较两组之间的DASS-21得分，并使用Wilcoxon符号秩检验比较干预前后的DASS-21得分。
■40名符合条件的母亲被随机分配：20名归干预组，20名归对照组。两组产妇和新生儿的基线特征相似。在基线或研究干预后，两组之间的DASS-21评分没有显着差异。实验组介入前后的DASS-21评分或其各个组成部分均无差异。对照组在第1周和第4周之间，DASS-21的总评分和DASS-21的焦虑成分显着降低。
■在这项随机对照试验研究中，根据DASS-21问卷的测量，在早产儿培养箱中播放的母亲声音对母亲的心理健康没有任何影响。在这项初步研究中获得的数据在未来的RCT（随机对照试验）中很有用，以解决这一重要问题。
