Aim To describe the development of the parent‐rated Hand‐Use‐at‐Home questionnaire ( HUH ) assessing the amount of spontaneous use of the affected hand in children with unilateral paresis, and to test its internal structure, unidimensionality, and validity. Method Parents of children with unilateral cerebral palsy ( CP ) and professionals participated in the development of the HUH . To examine internal validity, data of 322 children (158 males, 164 females; mean age 6y 7mo, standard deviation [ SD ] 2y 1mo) with unilateral CP ( n =131) or neonatal brachial plexus palsy ( NBPP ) ( n =191) were collected. Rasch analysis was used to examine discriminative capacity of the 5‐category rating scale as well as unidimensionality and hierarchy of the item set. Additionally, data of 55 children with typical development (24 males, 31 females; 6y 9mo, SD 2y 5mo) were used to examine construct validity. Results The 5‐category rating scale was disordered in all items and was collapsed to obtain the best discriminating sum score. Ten misfitting or redundant items were removed. Eighteen hierarchically ordered bimanual items fitted the unidimensional model within acceptable range. The HUH significantly discriminated between the three groups (children with typical development, NBPP , unilateral CP ; H (2) =118.985, p <0.001), supporting its construct validity. Interpretation The HUH is a valid instrument to assess the amount of spontaneous use of the affected hand in children with unilateral upper‐limb paresis.
