The field of special education has made great strides in identifying interventions that work. These practices have been described as evidence-based because they were effective across numerous studies. However, scholars in the field are also acutely aware that not all evidence-based practices will be equally effective for all children. Because of this, we sought to gain a better understanding of just who participated in single-case research design studies published in two early childhood journals from 2011 through 2020. Demographics for 267 participants from 67 studies were coded and statistically compared with federal data. Results suggest an overrepresentation of male participants, an overrepresentation of Black children, an overrepresentation of children diagnosed with autism, and an underrepresentation of Hispanic/Latinx children.

特殊教育领域在确定有效的干预措施方面取得了长足的进步。这些做法被描述为基于证据的做法，因为它们在众多研究中都有效。然而，该领域的学者也敏锐地意识到，并非所有基于证据的做法对所有儿童都同样有效。正因为如此，我们试图更好地了解谁参与了 2011 年至 2020 年发表在两份幼儿期刊上的单案例研究设计研究。对来自 67 项研究的 267 名参与者的人口统计数据进行了编码，并与联邦数据进行了统计比较。结果表明男性参与者的比例过高，黑人儿童的比例过高，被诊断患有自闭症的儿童比例过高，西班牙裔/拉丁裔儿童的比例过低。
