  1. Reliability and validity of the Asthma Quality of Life Questionnaire-Marks in a sample of adult asthmatic patients in the United States.

    Article - En anglais

    To render quality-of-life scores on an instrument acceptable for cross-national comparison, the instrument's reliability and validity must be established in all countries in question.

    The Asthma Quality of Life Questionnaire-Marks (AQLQ-M) was developed in Australia, where it was shown to have good reliability and validity.

    However, no attempt had been made to determine the psychometric properties of the AQLQ-M and its domains (ie, Breathlessness, Mood, Social, and Concerns) in the United States.

    The objectives of the present study were to administer the AQLQ-M to a sample of adult asthmatic patients in the United States (N=106) and assess (1) the acceptability of the AQLQ-M to respondents, (2) the internal consistency of the AQLQ-M and its domains, and (3) the construct validity of the AQLQ-M and its domains.

    Results indicated that respondents did not have difficulty answering the questions in the AQLQ-M.

    The Cronbach coefficient alpha value for the AQLQ-M was 0.94.

    The Cronbach coefficient alpha value for individual domains ranged from 0.84 to 0.91, providing evidence of good internal consistency reliability for the AQLQ-M and its domains.

    Pearson product-moment correlations between the domain scores ranged from 0.62 to 0.88, indicating that the domains were related but separate aspects of asthma-specific quality of life, as measured by the AQLQ-M. (...)
