Autism spectrum disorders (ASD) often go undetected in toddlers. The Modified Checklist for Autism in Toddlers (M-CHAT) was used to screen 3,793 children aged 16-30 months from low- and high-risk sources; screen positive cases were diagnostically evaluated. Rescreening was performed on 1,416 children aged 42-54 months. Time 1 Positive Predictive Value (PPV) was .36 for the initial screening and .74 for the screening plus follow-up telephone interview; values were similar for Time2 PPV. When separating referral sources, PPV was low for the low-risk sample but acceptable with the followup telephone interview. Children with ASD from the low-risk and high-risk samples were highly similar. Results indicate that the M-CHAT continues to be a promising instrument for the early detection of ASD.
自闭症谱系障碍(ASD)在幼儿中常常未被发现。使用改良幼儿自闭症检查表(M-CHAT)对来自低风险和高风险群体的3793名16至30个月大的儿童进行筛查;对筛查呈阳性的病例进行诊断评估。对1416名42至54个月大的儿童进行了再次筛查。第一次筛查时的阳性预测值(PPV)为0.36,筛查加后续电话访谈时为0.74;第二次PPV值相似。当区分转诊来源时,低风险样本的PPV较低,但后续电话访谈时可接受。来自低风险和高风险样本的ASD儿童高度相似。结果表明,M-CHAT仍然是早期检测ASD的一种很有前景的工具。
