title: [Development and validation of patient's knowledge measurement tools: The model of the Questionnaire de Connaissances sur l'Asthme destiné aux Patients Adultes (QCA-PA)].
abstract: BACKGROUND
  Poor asthma knowledge among asthmatic patients contributes to poor control of the disease. Education is a priority, but it needs a good assessment of the patient's knowledge.
  
  
  OBJECTIVE
  To give a patient's knowledge questionnaire development method following the example of the Questionnaire de Connaissances sur l'Asthme destiné aux Patients Adultes (QCA-PA).
  
  
  METHODS
  The QCA-PA was developed according to Dussault, Valois and Frenette's seven steps and includes 54 "true/false/don't know" items. A total of 101 asthmatic adults completed the questionnaire four times during three visits over a period of about one month. On the second visit, it was answered twice, before and after an individualized education session on asthma.
  
  
  RESULTS
  The QCA-PA demonstrates different proofs of validity: content, response process, internal structure, relationship to other variables, and consequences of testing. Confirmatory factorial analysis showed a unidimensional structure.
  
  
  CONCLUSIONS
  QCA-PA is a new rigorously validated knowledge measurement tool based on the most recent international recommendations. It could help health professionals to better target their educational interventions towards asthma patients.
