Abstract
Health-related quality of life (HRQoL) was evaluated in a sample of alcohol-dependent patients with the 36-item Medical Outcome Study Short-Form Health Survey (MOS-SF-36). the instrument was administered to 147 patients (77% males), aged 26–78, with a DSM-III-R diagnosis of alcohol dependence. the Hamilton Depression Scale (HDS), the Severity of Alcohol Dependence Questionnaire (SADQ), and the Addiction Severity Index (ASI) were also administered to the first 100 patients included in the study. the reliability and validity of the MOS-SF-36 were evaluated. Test-retest intraclass coefficients for a 10-day interval were in the range. 65 to. 79, whereas the Cronbach a coefficient indicated good internal consistency (range. 70 to. 89). Compared to scores observed in the general population, MOS-SF-36 scores for alcohol-dependent patients were relatively low (indicating worse perception of HRQoL), especially in the psychological and role dimensions (range 52/100 to 55/100), but were closer to populational values in the physical and functional dimensions (range 61/ 100 to 75/100). the highest correlation between MOS-SF-36 dimensions and HDS was found in the MOS-SF-36 “mental health” dimension (r = –.56, p. 001); this dimension was also correlated highly with the psychiatric dimension of the ASI (r = -.73, p <. 001). the eight dimensions of the MOS-SF-36 were 21% to 127% lower in patients with HDS greater than or equal to 16 (major depression) compared to those with HDS less than or equal to 7 (absence of depression). the MOS-SF-36 dimensions were 10% to 141% lower in patients with high ‘'ASI alcohol'' scores, indicating worse HRQoL profiles with a higher severity of alcohol dependence. the MOS-SF-36 presents good criteria for reliability and validity in alcohol-dependent patients. the results suggested that alcohol-dependent patients perceived their problems more as psychological than physical. the severity of alcohol dependence and depression seemed to influence the perception of HRQoL negatively.
