Vineland descriptors: high (scores of 130–140), moderately high (scores of 115–129), adequate (scores of 86–114), moderately low (scores of 71–85) and low (scores of 20–70); yrs: years.
SD Standard deviation; IQR Interquartile range; ABC Adaptive behavior composite; SI Section I of NPCRS; SIII Section III of NPCRS.
*Using Spearman test, only significant moderate or strong correlations with the NPCRS sections are shown: SI for section I, SII for section II, and SIII for section III.
