Interventions designed for children with disabilities and their families should be socially valid. Parent-implemented Communication Strategies-Storybook (PiCSS) is an intervention package designed to coach parents on shared storybook reading and naturalistic teaching strategies. In PiCSS program, the participating parents used the communication teaching strategies with high fidelity, and children responded more to their parents’ communication. To evaluate the social validity of PiCSS, we designed video-based rating surveys and collected data from masked raters (college students and practitioners). In total, 120 raters evaluated 12 1-min video clips. Quantitative analyses revealed that all raters scored coaching videos significantly higher than baseline videos for parent and child outcomes, indicating the PiCSS program had positive outcomes in parent–child interactions.

使用蒙面评分者评估家长实施的沟通干预的社会有效性

为残疾儿童及其家庭设计的干预措施应具有社会有效性。家长实施的沟通策略故事书 (PiCSS) 是一个干预包，旨在指导家长分享故事书阅读和自然主义教学策略。在PiCSS项目中，参与的家长采用了高保真的沟通教学策略，孩子对家长的沟通反应更积极。为了评估 PiCSS 的社会效度，我们设计了基于视频的评分调查，并从蒙面评分者（大学生和从业者）那里收集了数据。总共有 120 位评估者评估了 12 个 1 分钟的视频剪辑。定量分析显示，所有评分者对指导视频的评分均显着高于父母和孩子结果的基线视频，
