Validity of the Household and Leisure Time Activities questionnaire (HLTA) in a multiethnic HIV-positive population

As individuals with HIV/AIDS continue to have longer life expectancies, it is vital that other health outcomes, such as functional status, be considered. The purpose of this study was to explore the psychometric properties of a new functional status measure, the Household and Leisure Time Activities (HLTA) questionnaire, in a multiethnic low-income HIV/AIDS population. The HLTA is an 11-item questionnaire consisting of two scales designed to assess an individual's ability to perform routine home activities (household functioning scale) and to participate in leisure time activities (leisure-time functioning scale). The HLTA was administered, in the form of self-report questionnaires, to 385 consecutive patients seen at a comprehensive HIV/AIDS care facility serving low-income residents of Houston, Texas. Various psychometric procedures were then performed to assess properties, including reliability, construct validity, and concurrent validity. Reliability, assessed by Cronbach's alpha, was good for both scales (0.92, household functioning; and 0.94, leisure-time functioning). Validity was supported by findings from the confirmatory factor analysis and findings from the concurrent validity analyses. Overall, the results indicated that the HLTA has satisfactory psychometric properties and is appropriate for use with multicultural low-income HIV/AIDS patients.
