Background/aim: The Assessment of Children's Hand Skills is a new assessment that utilises a naturalistic observational method to capture children's real-life hand skill performance when engaged at various types of daily activities in everyday living contexts. The Assessment of Children's Hand Skills is designed for use with 2- to 12-year-old children with a range of disabilities or health conditions. The study aimed to investigate construct validity of the Assessment of Children's Hand Skills in Australian children.
Methods: Rasch analysis was used to examine internal construct validity of the Assessment of Children's Hand Skills in a mixed sample of 53 children with disabilities (including autism spectrum disorder, developmental/genetic disorders and physical disabilities) and 85 typically developing children. External construct validity was examined by correlating with three questionnaires evaluating daily living skills and hand skills.
Results: Rasch goodness-of-fit analysis suggested that all 22 activity items and 19 of 20 hand skill items in the Assessment of Children's Hand Skills measured a single construct. The Assessment of Children's Hand Skills items were placed in a clinically meaningful hierarchy from easy to hard, and the difficulty range of the items also matched the majority of children with disabilities and typically developing preschool-aged children. Moderate to high correlations (0.59 ≤ Spearman's ρ coefficients ≤ 0.89, P < 0.01) were found with the assessments of daily living and fine motor skills.
Conclusion: This study provided preliminary evidence supporting the construct validity of the Assessment of Children's Hand Skills for its clinical application in assessing children's real-life hand skill performance in Australian contexts.
