Validity of The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS): a daily activity criterion checklist for infants and toddlers
The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS) is a 50-item, criterion-specified questionnaire that assesses a child’s adaptive skills in everyday context and can be used in high-risk follow-up settings to identify risk for adverse neurodevelopmental outcome. Our aim was to validate the WIDEA-FS by comparing a sample of typically developing children to children with special health needs and to compare results to the Capute Scales, which include domains of including both the Cognitive Adaptive Test (CAT) and the Clinical Linguistic and Auditory Milestone Scale (CLAMS).
Six hundred and sixty children (typically developing and having special healthcare needs) aged 0–36 months completed the WIDEA-FS, the CAT, and the CLAMS assessments.
Children with special health needs scored significantly lower on the WIDEA than those with typical development. WIDEA-FS subscales were significantly associated with the CAT (WIDEA-FS self-care 0.87, social cognition 0.89) and the CLAMS (WIDEA-FS communication 0.96, social cognition 0.92) tests.
The WIDEA-FS has concurrent validity with the CAT and CLAMS and construct validity in that children with special health needs have significantly poorer performance on the WIDEA-FS than children with typical development.
- The WIDEA-FS demonstrated both construct validity and concurrent validity with the Capute Scales, including the Cognitive Adaptive Test (CAT) and the Clinical Linguistic and Auditory Milestone Scale (CLAMS).
- This is the first study to validate the use of the WIDEA-FS in children with typical development and children with special healthcare needs.
- The WIDEA-FS is a quick and valid checklist that can be used to assess neurodevelopmental functioning during daily activities in typically developing children and those at risk for neurodevelopmental differences.
