Abstract

The Health-Related Quality of Life for Drug Abusers (HRQoLDA) test was designed to specifically evaluate quality of life among substance users. In this study, the validity and reliability of the English version of the HRQoLDA test are reported for the first time. A sample of 121 participants from inpatient and outpatient treatment facilities completed the HRQoLDA test. The mean HRQoLDA score was 45.9 (SD = 16.9), while the overall Cronbach's alpha coefficient was 0.905. The factorial analysis of the HRQoLDA test revealed a unidimensional structure. Convergent validity analyses demonstrated significant correlations between the HRQoLDA test scores and the scores of the World Health Organization Quality of Life Assessment-Bref Questionnaire in different dimensions. The results revealed that the HRQoLDA was successfully adapted to English. The HRQoLDA is a reliable research instrument for evaluating quality of life of substance users.
