The article describes the procedure and study outcomes of the construct validity of the Ukrainian version of Haemo-QoL questionnaire.
Objective: to investigate the construct validity (CV) of the Ukrainian version of the questionnaire for assessing the health-related quality of life (HR-QoL) of children with haemophilia.
Materials and methods. The survey data of 106 respondents-participants (53 children with haemophilia A and 53 their parents) were analysed by the correspondent method. The questionnaire survey was conducted using the pilot Ukrainian version of Haemo-QoL Questionnaire via individual and electronic interviewing. For assessing of joint pain intensity, the Wong-Baker Faces Pain Rating Scale (FPS) in 53 patients with haemophilia A was used. The construct validity (CV) assessment of questionnaire was conducted using the following methods: known-groups technique, correlation relationship analysis within the questionnaire structure and using «external criteria».
Results. It was found that the worst HR-QoL was in the group of patients with severe course of haemophilia A, and the best one was admitted in mild course of the disease; HRQoL evaluated by parents was lower than by their children. HRQoL significantly deteriorated with increase in the number of haemarthrosis; the indicators of the «Physical Health» scale reliably correlated with the FPS indicators. The highest correlation coefficients were found between the contentlike scales: Physical Health and Sport & School, which are the least correlated with the social functioning scales.
Conclusions. The pilot Ukrainian version of Haemo-QoL Questionnaire has sufficient CV for its use in the national practical and theoretical medicine as a HRQoL assessment instrument in haemophiliac patients and their parents.
Key words: haemophilia A, children, validation of questionnaire, quality of life, validity.
