Randomized controlled psychosocial treatment studies on selective mutism (SM) are lacking.
Overall, 24 children with SM, aged 3-9 years, were randomized to 3 months treatment (n = 12) or wait list (n = 12). Primary outcome measure was the School Speech Questionnaire.
A significant time by group interaction was found (p = .029) with significantly increased speech in the treatment group (p = .004) and no change in wait list controls (p = .936). A time by age interaction favoured younger children (p = .029). Clinical trail registration: Norwegian Research CouncilNCT01002196.
The treatment significantly improved speech. Greater improvement in the younger age group highlights the importance of an early intervention.
缺乏关于选择性缄默症（SM）的随机对照心理社会治疗研究。
总体而言，24名年龄在3至9岁的SM儿童被随机分为接受3个月治疗组（n = 12）或等待名单组（n = 12）。主要结局指标是学校言语问卷。
发现了显著的组间时间交互作用（p = .029），治疗组的言语能力显著提高（p = .004），而等待名单对照组无变化（p = .936）。年龄与时间的交互作用有利于年幼儿童（p = .029）。临床试验注册：挪威研究理事会NCT01002196。
该治疗显著改善了言语能力。较年轻年龄组有更大改善突出了早期干预的重要性。
