Social emotional development in infancy is a predictor of outcomes in later life, yet there is little evidence of effectiveness for parenting interventions designed to enhance social emotional wellbeing in infancy. An 18-month two-arm randomized controlled pilot trial evaluated the feasibility of a definitive trial of Incredible Years (IY) Infant and Toddler parent programs delivered in a proportionate universal model, called Enhancing Social-Emotional Health and Wellbeing in the Early Years (E-SEE) Steps. Intervention families received an IY Babies book (universal dose), followed by the IY Infant and/or the Toddler group-based programs, based on parent depression (PHQ-9) and/or child social emotional development (ASQ:SE-2) scores. Control parents received services as usual. Parents from two English local authorities with a child eight-weeks-old or younger participated, and were block randomized using a web-based system. Primary endpoints for the study were feasibility parameters relating to recruitment, retention, intervention fidelity and appropriateness of measures. 205 participants were randomized (152:53, intervention:control). Our target was 288 parents. Trial retention rate was higher than expected, with a completion rate of 88% (n = 181, 137:44) at follow-up 3; equating to 94% of 192 expected participants. Intervention uptake was lower than expected. Fidelity of delivery was acceptable and measures were deemed appropriate. A definitive trial is feasible with design amendments to include: introduction of a child screener for intervention eligibility; enhanced intervention material; revised sample size and random allocation ratio. Our internal pilot became an external pilot due to these changes.

婴儿期的社会情感发展是晚年生活结果的预测指标，但几乎没有证据表明旨在提高婴儿期社会情感福祉的育儿干预措施的有效性。一项为期 18 个月的两臂随机对照试验性试验评估了一项关于 Incredible Years (IY) Infant and Toddler 父母计划的最终试验的可行性，该试验以比例通用模型提供，称为 Enhancing Social-Emotional Health and Wellbeing in the Early Years (E - 见）步骤。干预家庭收到了一本 IY 婴儿书（通用剂量），然后是基于父母抑郁症 (PHQ-9) 和/或儿童社交情绪发展 (ASQ:SE-2) 的 IY 婴儿和/或幼儿小组计划分数。对照组父母照常接受服务。来自两个英国地方当局的父母和一个八周或更小的孩子参加了，并使用基于网络的系统进行随机分组。该研究的主要终点是与招募、保留、干预保真度和措施适当性相关的可行性参数。205 名参与者被随机分配（152:53，干预：对照）。我们的目标是 288 位家长。试验保留率高于预期，在随访 3 时完成率为 88% (n = 181, 137:44)；相当于 192 名预期参与者的 94%。干预吸收低于预期。交付的保真度是可以接受的，措施被认为是适当的。一项最终试验是可行的，设计修改包括： 引入儿童筛查器以确保干预资格；增强的干预材料；修订后的样本量和随机分配比率。由于这些变化，我们的内部飞行员变成了外部飞行员。
