Psychometric assessment of the Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV) in a sample of HIV-infected women.
Since the late 1980s, several HIV-specific quality of life instruments have been developed; however, little testing has been done in terms of their validity and reliability for HIV-infected women. The purpose of this study was to test the content validity, concurrent validity, internal consistency, and test-retest reliability of the Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV) in a sample of 85 HIV-infected women. The MQOL-HIV is a 40-item scale comprised of 10 dimensions. Most of the items and all of the domains were determined content valid but revision of some of the items and domains is recommended. Concurrent validity was measured between the MQOL-HIV and the MOS-HIV and ranged from 0.51-0.81 between similar domains. Of the 10 domains and the entire instrument, 7 had a Cronbach's alpha over 0.70 (range 0.43-0.92). Eight domains and the entire instrument achieved test-retest correlation coefficients over 0.70 (range 0.60-0.96). Although some revision may make the scale more content-valid for HIV-infected women, given due care in the interpretation of results, the MQOL-HIV can be used with female populations in its current form.
