Factor validity of alcohol use disorders identification test (AUDIT) using robust estimations in ecuadorian adolescents

Objective: Confirm the three correlated factors model of the Alcohol Use Disorders Identification Test (AUDIT) using robust estimations and evaluate its internal consistency with a sample of Ecuadorian adolescents. Method: Descriptive and instrumental analysis that includes confirmatory factor analysis with robust estimation and the calculation of its internal consistency. Participants: A total of 1113 adolescents in which 56.1% are men and 43.9% are women), and they were between 11 and 19 years old ($\overline{X} $= 14.9 years; s = 1.67). Students from eight educational centres in Cotopaxi (54.1%) and Tungurahua (45.9%) in Ecuador were also included. Results: The three correlated factors model from the AUDIT is confirmed with χ2 = 95.67; P < 0.001; df = 32; χ2/df = 2.98; comparative adjustment index = 0.93; Tucker-Lewis index = 0.90; standardized root mean square residual = 0.046; root mean square error of approximation = 0.042; 95% confidence interval [0.033-0.052]. Conclusions: The three correlated factors model from the AUDIT using robust estimations has an adequate fit and is also reliable in a sample of Ecuadorian adolescents.
