Abstract

This descriptive cross–sectional research aimed to develop and test adaptive behavior questionnaire (ABQ) among people living with HIV who received antiretroviral therapy in Thailand’s Universal Coverage Scheme Project. The study involved two phases. Phase I, questionnaire development, consisted of 6 steps: (1) defining the concept; (2) generating an item pool; (3) defining the choices of response to items; (4) reviewing items; (5) conducting a pilot study; and (6) selecting items for analysis. Inter–rater agreement and item-level content validity index for the first draft of the questionnaire (45 items) were 0.92 and 0.8082, relatively. Phase II involved the final draft of instrument (21 items), using psychometric property evaluation, Pearson’s correlation coefficient to analyze the concurrent validity, predictive validity, internal consistency reliability, and test–retest reliability. Psychometric testing was systematically employed to evaluate the principle component factors which were named “adaptive behavior factors”. Generally, the consistency of this questionnaire was found highly reliable. Additionally, concurrent criterion–related validity was examined by investigation of the correlations of the nine-adaptive behavior factor structure to physical function mode, self–concept mode, role-function mode and interdependence adjustment. The 7 days and twice within 30 days test-retest reliability coefficient of the ABQ indicated good reliability and provided sufficient empirical evidence to support the validity and reliability of the questionnaire.
