  1. ADOS autism diagnostic observation schedule, CCC-2 Children’s Communication Checklist 2nd Edition, CELF Clinical Evaluation of Language Fundamentals (preschool 2nd Edition or IV), PPVT-III Peabody Picture Vocabulary Test 3rd Edition, VABS-II Vineland Adaptive Behavior Scales 2nd Edition
  2. aIndicated pairwise group differences (< or >) based on p values adjusted using the False Discovery Rate method (q < .05) [63]
  3. bStandard scores (M = 100, SD = 15)
  4. cFor PIQ, the ALI group did not differ significantly from either the SLI or the ALN groups
  5. dThis score ranges from 0–10 [59]
  6. ePositive SIDI scores indicate primarily structural language difficulties; negative scores indicate primarily pragmatic/social difficulties
