Turkish Translation, Cross-Cultural Adaptation, Validity, and Reliability of the ABILHAND-Kids Young CP Scale (ABILHAND-KYCTR)

Parents or primary caregivers of children aged 2 to 7 years diagnosed with cerebral palsy, participating in the Turkish cross-cultural adaptation and validation study of the ABILHAND-Kids Young CP scale.

Administration of the Turkish version of the ABILHAND-Kids Young CP questionnaire to evaluate manual ability in children with cerebral palsy. No medical, therapeutic, or surgical intervention is applied.

Evaluates manual ability and perceived difficulty in daily activities requiring upper limb use in children aged 2 to 7 years with cerebral palsy, based on parent or primary caregiver reports. The scale consists of 17 items, each scored on a 3-point ordinal scale (0 = impossible, 1 = difficult, 2 = easy). The total raw score ranges from 0 to 34 (converted into a linear Rasch measure from 0 to 100). Higher scores indicate better manual ability (a better outcome).

Evaluates children's bimanual use, functional performance and participation levels in daily life activities, and strategies for using the affected hand based on parent or primary caregiver reports to assess convergent validity. The questionnaire assesses 27 bimanual activities across three subscales (Grasp Efficacy, Time Taken, and Feeling Bothered) on a 4-point ordinal scale (1 to 4), converted into linear scaled scores ranging from 0 to 100 for each subscale. Higher scores indicate better hand-use experience, higher functional performance, and less perceived difficulty (a better outcome).
