Background: Our objective was to test the validity of the Kinder Infant Development Scale (KIDS) rated by families of children.
Methods: A total of 317 children (151 healthy children and 166 disabled patients) participated in this prospective study. To prove the validity of the family-rated KIDS, period of gestation, birth weight, diagnosis, age, and results of the family-rated Ages & Stages Questionnaires, Third Edition (ASQ-3), family-rated Ability for Basic Movement Scale for Children (ABMS-C) and Ability for Basic Movement Scale for Children type T (ABMS-CT), and staff-rated Functional Independence Measure for Children (WeeFIM) were recorded.
Results: Developmental age and quotient on the 9 subscales of the family-rated KIDS had appropriate internal consistency (Cronbach’s α=0.969, 0.942). The total developmental age assessed with KIDS correlated with age, the total scores for the ABMS-C and ABMS-CT, the motor and cognitive WeeFIM (r=0.839-0.894, p<0.01). The total developmental quotient by KIDS was correlated with the period of gestation and birth weight of the children by low correlation coefficient (r=0.353, 0.299, p<0.01).
Conclusions: This study provides evidence for the validity of the family-rated KIDS for assessing the developmental age of children in early childhood.
