Psychometric Properties of the Mini Pediatric Asthma Quality of Life Questionnaire in a US Sample
The 13 item Mini Pediatric Asthma Quality of Life Questionnaire (MiniPAQLQ) was developed to measure asthma specific quality of life in children. However, no validation studies have been conducted in the United States. This study aimed at determining the psychometric properties of the MiniPAQLQ in a US sample. Children aged 7 17 years and with an asthma diagnosis (n 193) were identified from primary care clinics within an integrated healthcare system in the Southeastern United States. Participants completed surveys consisting of the MiniPAQLQ and the control module of the Asthma Therapy Assessment Questionnaire (ATAQ) Convergent validity was determined based on association between the MiniPAQLQ and ATAQ scores. Internal consistency reliability was determined from Cronbach's alpha coefficients for the MiniPAQLQ subscales (symptoms, emotions, and activities) Item convergent validity was examined based on corrected item total correlations. Item discriminant validity was determined by comparing corrected
