| description | In México there are instruments with adequate psychometric properties evaluating alcohol consumption, as well as several aspects of its use and risk perception (refer to Calleja, 2011). However, so far, a scale measuring both alcohol consumption and other psychoactive substances in a brief and precise way has not been validated in México. This study aimed to examine the psychometric properties of the CARLOS (CRAFFT) instrument by Knight, Sherrit, Shrier, Harris and Chang (2002) in a sample of 220 Mexican university students. The instruments CARLOS (CRAFFT) and AUDIT were applied to Mexican university students. The self-administered test technique was used and the instruments were applied inside the classroom. A 1 was assigned to an affirmative answer and 0 for a negative answer. The average age of the participants was 20 years (range, 18 to 25 years). The CARLOS (CRAFFT) instrument showed moderately high internal consistency levels (Cronbach’s alpha = .73). The cutoff point of 2 offers the best combination of sensibility (.86) and specificity (.73) with a positive predictive value (.52) and a negative predictive value (.93). The area under the ROC curve was .79 and Pearson’s r correlation between the CARLOS (CRAFFT) and the AUDIT instrument was .67 (p < 0.01). The CARLOS (CRAFFT) instrument is sufficiently valid and reliable for testing psychoactive substances consumption in Mexican university students. |

En México existen instrumentos con adecuadas propiedades psicométricas que evalúan el consumo de alcohol, así como diversos aspectos asociados a su consumo y percepción de riesgo (véase Calleja, 2011). Sin embargo, hasta ahora, no se ha identificado una escala creada o validada en el país que mida, al mismo tiempo, el consumo de alcohol y otras sustancias psicoactivas de forma breve y precisa. El objetivo de este trabajo fue examinar las propiedades psicométricas del instrumento CARLOS (CRAFFT) de Knight, Sherrit, Shrier, Harris y Chang (2002) en una muestra de 220 estudiantes universitarios mexicanos. Se aplicaron los instrumentos CARLOS (CRAFFT) y AUDIT a estudiantes universitarios. Se optó por la técnica del cuestionario auto-administrado. Se aplicaron los instrumentos dentro del salón de clases. Se asignó 1 a la respuesta afirmativa y 0 a la respuesta negativa. La edad promedio de los participantes fue de 20 años (rango, 18 a 25 años). El instrumento CARLOS (CRAFFT) mostró niveles moderadamente altos de consistencia interna (Alfa de Cronbach = .73). El punto de corte de 2 ofrece la mejor combinación de sensibilidad (.86) y especificidad (.73). Valor predictivo positivo (.52) y valor predictivo negativo (.93). El área bajo la curva (ROC) fue de .79. La correlación r de Pearson con el instrumento AUDIT fue de .67 (p <0.01). El instrumento CARLOS (CRAFFT) es suficientemente válido y confiable para la tamización del consumo de sustancias psicoactivas en estudiantes universitarios mexicanos. Facultad de Psicología.
