Popis: Objective: Health-related quality of life is an important measure in evaluations of the management of childhood asthma. In this study, we assessed psychometric properties, responsiveness, and longitudinal and cross-sectional construct validity of the Dutch version of the 23-item Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Methods: The study group consisted of 238 6-18-year olds with asthma, with complete respiratory symptom diaries in the course of one winter season; each child had one (or more) PAQLQ measurement(s) concerning one (or more) week(s) with relatively many symptoms (n = 238). Each child also had one PAQLQ measurement concerning another week with relatively few symptoms (n = 238). The PAQLQ scores of the 238 children for a week with few symptoms (the symptom diary scores remained below a predefined level everyday) were compared with their PAQLQ scores for another week with many symptoms (on day 1 of that week, symptom diary scores had been above the predefined level). Additionally, in a subgroup of the study group that had experienced two or more 'weeks with many symptoms' (n = 101), we compared the PAQLQ-scores for two different weeks with many symptoms of these children. Results: Only the domain Emotions showed a ceiling effect (>25% had the maximum score). All Cronbach's a's of the PAQLQ total score and domains were > 0.70, except for Activities (alpha = 0.54). Mean PAQLQ-scores were significantly different (p
