In this systematic review, we examined the rigor and outcomes across 27 object play intervention studies using single-case research methodology. We focused on studies including children age 5 years or younger and examined several descriptive characteristics including materials, instructional packages, and settings. We also analyzed the facilitation and measurement of generalized play and several methodological features including quality, rigor, and visual analysis procedures. Overall, the identified studies demonstrated positive outcomes, although quality and rigor limited interpretations of the outcomes. Previous reviews also have noted strong outcomes and weak to moderate quality for single-case studies. Our results should be interpreted with caution given previous reviews of play intervention studies identified strong outcomes and quality from group-design studies. Additional replications testing robust interventions using single-case research with strong methodological rigor are warranted.

残疾幼儿的教学对象游戏：方法和严格性的系统评价

在本系统评价中，我们使用单例研究方法研究了27项对象游戏干预研究的严格性和结果。我们专注于研究，包括5岁以下的孩子，并研究了一些描述性特征，包括材料，教学包和设置。我们还分析了广义比赛的促进和衡量以及包括质量，严谨性和视觉分析程序在内的几种方法学特征。总体而言，虽然质量和严格性对结果的解释有限，但已确定的研究显示出积极的结果。以往的评论还指出，单例研究的结果强而质量低。鉴于先前对游戏干预研究的评论从小组设计研究中确认了强劲的结果和质量，因此应谨慎解释我们的结果。使用严格的方法严格的单案例研究来测试强大的干预措施的其他复制是有保证的。
