Psychometric evaluation of the Quality of Life Interview, Brief Version, in injection drug users.
The authors investigated the psychometric characteristics of the Quality of Life Interview, Brief Version (QOLI-BV; A. F. Lehman, 1995) in 126 injection drug users recruited for a clinical trial. The QOLI-BV assesses global and domain-specific quality of life. Participants completed the instrument at baseline and 3 and 6 months later. Most scales showed acceptable internal consistency. Convergent and discriminant validity were demonstrated through correlations with the SF-36, the Beck Depression Inventory, and demographic variables. Scale means rose over time, suggesting that the QOLI-BV is sensitive to change. Unexpectedly, lower baseline QOLI-BV scores predicted opiate abstinence at follow-up. The QOLI-BV appears to be an acceptable quality-of-life measure for use in clinical trials of opioid dependence treatments.
