Background:
Chronic respiratory diseases are an important problem in Chile, causing disability and worsening the quality of life.
Aim:
To validate the Spanish version of the Chronic Respiratory Questionnaire (CRQ) to be used in Chilean population.
Material And Methods:
The CRQ was applied to 38 patients with chronic respiratory diseases. At the same time the functional and physiologic status of patients (the 6 Minute Walking Test and spirometry) was assessed in an independent and blinded fashion.
Results:
CRQ scores were associated with 6 Minute Walking Test and forced expiratory volume results (p < 0.01 adjusted by age, sex and smoking). The Internal Consistency analysis showed a Cronbach alpha between 0.60 and 0.89.
Conclusions:
Considering the construct validation as an on-going process, the present results give additional evidence supporting the use of the CRQ in Chilean population to evaluate the health-related quality of life of patients with chronic respiratory diseases.
