Abstract
PEREZ-LOPEZ, Alejandro et al. Three versions of the Short Alcohol Dependence Data Questionnaire (SADD) in Mexican population: a comparative analysis of psychometric properties and diagnostic accuracy. Salud Ment [online]. 2015, vol.38, n.4, pp.281-286. ISSN 0185-3325. https://doi.org/10.17711/sm.0185-3325.2015.038.
BACKGROUND:
The Short Alcohol Dependence Data Questionnaire (SADD) has shown good reliability and validity in previous studies. In Mexico, although it is widely used in addiction treatment centers, little is known about its psychometric properties and diagnostic accuracy.
OBJECTIVE:
Hence, this study performed a Confirmatory Factorial Analysis (CFA) on three SADD versions (15, 14 and 12 items) and examined their operating characteristics.
METHOD:
The sample included 570 individuals from the 30 Addiction Residential Centers localized in the central zone of Mexico.
RESULTS:
The three versions showed an internal consistency of >.90, fair goodness-of-fit, and significant correlations with the Mini International Neuropsychiatric Interview (MINI) 5.0 Alcohol dependence (AD) diagnostic criteria. The analysis of the operating characteristics revealed that each version accounted for 84-85% of the area under the curve (AUC).
DISCUSSION AND CONCLUSION:
The three SADD versions possess reliability and validity properties for the assessment of the alcohol dependence syndrome (ADS) and adequate diagnostic accuracy for the improvement of patients with AD in residential settings.
Keywords : Alcohol dependence; SADD; psychometric properties; construct validity; diagnostic accuracy.
