Development and Psychometric Properties of the Arabic Parent Nutritional Assessment Scale (A-PNAS) for Children with Developmental Disabilities.

To describe the development of the Arabic-Parent Nutritional Assessment Scale (A-PNAS), and to examine construct and known-group discriminant validity, internal consistency, and test-retest reliability of the A-PNAS. A cross-sectional design was used. Participants were 130-children with CP (mean age = 4.26 ± 3.29 years) who were registered in the national CP registry of Jordan with a matching group of 130-children with typical development (mean age = 4.65 ± 3.54 years). Parents completed the developed A-PNAS through a structured phone interview. Parents of children with CP confirmed their child's level of gross motor function classification system. Exploratory factor analysis identified three subscales in the A-PNAS: , , and which explained 31.6% of the variance in nutritional problems of children with CP. Cronbach's alpha indicated acceptable internal consistency for (α = 0.61) and (α = 0.67)subscales. Parents of children with CP reported that their children had more food intake, health, and behavioral problems compared to children with typical development (<.001). Test-retest reliability was excellent for the subscales of the A-PNAS (ICCs = 0.96, 0.98, 0.96). The findings provide support for the face validity, construct validity, internal consistency, Known-Groups discriminant validity, and test-retest reliability of the A-PNAS.
