Comparison of the Kyoto Scale of Psychological Development 2001 with the parent-rated Kinder Infant Development Scale (KIDS)

For high DQ group, the KSPD P-M domain was consistently related to parent-reported physical/motor development, the C-A domain primarily reflected a child's fine motor skills and his/her ability to understand and follow verbal instructions provided by adults, while the L-S domain was associated with parent-reported language ability. For low DQ group, the effect of global delay increased overall correlations between each domain and subscale. Further studies are necessary to replicate the findings in a larger sample including typical children.
