ABSTRACT In the present study, we examined the rate of DSM-5 Social (Pragmatic) Communication Disorder (SCD) symptoms and diagnoses in a sample of school-aged youth at risk for ASD. Diagnostic evaluations were performed on 254 participants who had previously screened at risk for ASD via the Social Communication Questionnaire-Lifetime Version (SCQ). While 19 participants met all four clinical criteria for SCD, 18 of these (95%) also met criteria for DSM-5 ASD, effectively ruling out an SCD diagnosis. The one participant who met the criteria for SCD met DSM-IV criteria for PDD-NOS but did not meet DSM-5 criteria for ASD due to RRBs in only one category. Given the high proportion of at-risk youth with social communication impairment, it is essential that interventions be developed and made more readily available to individuals both with and without diagnoses of ASD.

评估自闭症谱系障碍风险儿童的社交（语用）沟通障碍的发生率

摘要在本研究中，我们检查了样本中有ASD风险的学龄青年的DSM-5社交（语用）沟通障碍（SCD）症状和诊断率。对254位先前通过社交沟通问卷-终生版本（SCQ）筛查有自闭症风险的参与者进行了诊断评估。尽管有19位参与者符合SCD的所有四个临床标准，但其中18位（95％）也符合DSM-5 ASD的标准，有效地排除了SCD的诊断。符合SCD标准的一名参与者符合PDD-NOS的DSM-IV标准，但由于仅一种类别的RRB，不符合DSM-5的ASD标准。鉴于社交沟通障碍的高危青年比例很高，
