title: Evaluation of quality of life among the caregivers of asthmatic children: the new IFABI-R questionnaire.
abstract: BACKGROUND
  The health-related quality of life (HRQoL) of asthmatic children and their caregivers is correlated to management of the disease and the presence of certain morbidity indicators. The integral assessment of paediatric asthma must include the evaluation of HRQoL among the caregivers, although existing questionnaires only partially assess the dimensions of this aspect. The present study describes a new questionnaire for evaluating HRQoL among the caregivers, comprising three dimensions (functional, emotional, and socio-occupational).
  
  
  METHODS
  The study involves two phases. A total of 81 patients between 3 and 9 years of age and their caregivers participated in the first phase, involving a qualitative and psychometric study of the preliminary version of the questionnaire (IFABI). A total of 137 patients between 2 and 17 years of age and their caregivers participated in the second phase, in which the revised version of the questionnaire (IFABI-R) was developed and subjected to psychometric evaluation.
  
  
  RESULTS
  First phase: The IFABI showed important reliability and internal consistency (Cronbach alpha=0.93), concurrent validity requiring improvement, and a scantly clear internal structure. Second phase: The IFABI-R showed important reliability and internal consistency (Cronbach alpha=0.90), adequate concurrent validity, and a three-dimensional structure whose three factors correspond to the three dimensions of the questionnaire.
  
  
  CONCLUSIONS
  The good psychometric results obtained with the IFABI-R justify its use in paediatric asthmatic patients. The questionnaire is currently being scaled, and its sensitivity to change is being assessed.
