OBJECTIVE: To investigate cross-cultural validity of a newly developed Assessment
of Children's Hand Skills (ACHS) in children with and without disabilities.
SUBJECTS: One group of 138 Australian children and 134 Taiwanese children, age
range 2-12 years (a total of 149 typically developing children and 123 children
with disabilities). METHODS: Rasch model analysis was used to evaluate rating
scale performance, person-fit, and item unidimensionality of pooled data from the
ACHS. Rasch-based differential item functioning was used to evaluate differences
in item difficulties between cultural groups. RESULTS: The appropriateness of the
ACHS 6-level rating scale was confirmed in the pooled analysis. All 22 activity
items and 19 of 20 hand skill items in the ACHS formed a unidimensional scale.
The ACHS exhibited reasonable response patterns when applied to the composite
sample of Australian and Taiwanese children. Differential item functioning was
found in 7 activity items and 7 hand skill items. CONCLUSION: The ACHS can be
used to assess and compare children's hand skills across Australian and Taiwanese
cultural contexts with confidence. Adjustment for differential item functioning
may be used when pooling or comparing ACHS data from these cultural groups.
