Note. VABS-C = Vineland Adaptive Behavior Scales Communication Domain; VABS-M = Vineland Adaptive Behavior Scales Maladaptive Behavior Index- high scores indicate increased maladaptive behaviors; PPVT-4 = Peabody Picture Vocabulary Test–4; CCS = Complexity of Communication Scale; Imitation-V = imitation of vocal/verbal/oral tasks. Age is age at start of data collection. Raw scores are reported; standard scores are presented in parentheses. CCS scores are based on a scale of 1-11 with 11 being highest. Imitation-V scores are number correct out of 8 from Early Steps Imitative Sequences Assessment. Child 4 is female.
