Note: MSEL = Mullen Scales of Early Learning. NVDQ/IQ = nonverbal developmental/intelligence quotient. VDQ/IQ = verbal developmental/intelligence quotient. CELF = Clinical Evaluation of Language Fundamentals. The between-subject effect of 5DNPCCSS domain was centered at the median value (Wechsler: 2; MSEL: 0; CELF: 1; Purdue: 1; Nine-hole: 2). Thus, the between-within interaction is interpreted as the additional expected change in outcome as a function of change in 5DNPCCSS domain score for a one-unit increase above the median between-subject 5DNPCCSS value. For the Nine-hole, higher scores reflect worse performance relative to normative data. For all other direct assessments, higher scores reflect better performance relative to normative data.
