Development and preliminary testing of a Paediatric Version of the Haemophilia Activities List (pedhal).
Worldwide, children with haemophilia suffer from limitations in performing activities of daily living. To measure such limitations in adults a disease-specific instrument, the Haemophilia Activities List (HAL), was created in 2004. The aim of this study was to adapt the HAL for children with haemophilia and to assess its psychometric properties. The structure and the main content were derived from the HAL. Additionally, items of the Childhood Health Assessment Questionnaire and the Activity Scale for Kids were considered for inclusion. This version was evaluated by health professionals (n = 6), patients (n = 4), and parents (n = 3). A pilot test in a sample of 32 Dutch children was performed to assess score distribution, construct validity (Spearman's rho) and reproducibility. Administration of the pedhal was feasible for children from the age of 4 years onwards. The pedhal scores of the Dutch children were in the high end of the scale, reflecting a good functional status. Most subscales showed moderate associations with the joint examination (rho = 0.42-0.63) and moderate-to-good associations with the physical function subscale of the CHQ-50 (rho = 0.48-0.74). No significant associations were found for the pedhal and the subscales mental health and behaviour, except for the subscales leisure and sport and mental health (rho = 0.47). Test-retest agreement was good. The pedhal is a promising tool, but further testing in populations with a higher level of disability is warranted to study the full range of its psychometric properties.
