Researchers estimate the prevalence of developmental language disorder (DLD) in 5-year-olds to be between 7% and 12%. Current identification systems in public schools typically favor referral identification formats over targeted or universal screenings. Public schools face unique challenges when assessing the value of screening measures for DLD that include real-world considerations such as administration, time, and resource constraints. This study used the positive predictive value (PPV) of the Redmond Sentence Recall (RSR) to assess its fidelity when administered by special education paraprofessionals. Our obtained PPV was compared across three areas: (a) previous studies that have utilized the RSR, (b) rates extrapolated from the participating school district's preexisting referral system from a previous study, and (c) expectations based on DLD prevalence.
Language screenings were conducted in two elementary schools using the RSR administered by school-based paraprofessionals trained on the screener protocol. One hundred sixty-four kindergarten students (age range: 5-6 years) were screened. Confirmatory testing was completed on all students who failed the screener.
Of the 164 students screened, 19 failed the RSR (11.5%), and 14 met criteria (8.5%) for DLD (PPV = .74). Our PPV was similar to previously published studies that utilized the RSR using research assistants and was higher than the PPV associated with teacher-based referrals from the participating school district.
The RSR represents a potentially useful screener for identifying children at risk for previously unidentified language disorders in public schools.
研究人员估计5岁儿童中发育性语言障碍(DLD)的患病率在7%至12%之间。公立学校目前的识别系统通常更倾向于转介识别形式,而非针对性或普遍性筛查。公立学校在评估DLD筛查措施的价值时面临独特挑战,其中包括管理、时间和资源限制等现实因素。本研究使用雷德蒙德句子回忆测试(RSR)的阳性预测值(PPV)来评估其由特殊教育辅助专业人员实施时的准确性。我们将获得的PPV在三个方面进行了比较:(a)以往使用RSR的研究;(b)根据参与学区先前研究中已有的转介系统推断出的比率;(c)基于DLD患病率的预期。
在两所小学进行语言筛查,使用由接受过筛查协议培训的校本辅助专业人员实施的RSR。对164名幼儿园学生(年龄范围:5至6岁)进行了筛查。对所有筛查未通过的学生完成了确诊测试。
在接受筛查的164名学生中,19名RSR测试未通过(11.5%),14名符合DLD标准(8.5%)(PPV = 0.74)。我们的PPV与之前发表的使用研究助理实施RSR的研究相似,且高于参与学区基于教师转介的PPV。
RSR是一种潜在有用的筛查工具,可用于识别公立学校中存在先前未被识别的语言障碍风险的儿童。
