Adaptación transcultural y validación del test CRAFFT como prueba de pesquisa para consumo problemático, abuso y dependencia de alcohol y otras sustancias en un grupo de adolescentes argentinos

Validación empírica del CRAFFT Abuse Screening Test en una muestra de adolescentes españoles

“…En primer lugar, a nivel de consistencia interna, se ha obtenido un valor α satisfactorio de ,74, superior al obtenido en el estudio de validación original de Knight et al (2002) (α = ,68) y al de otros trabajos (Bertini et al, 2015;Kelly et al, 2004;Subramaniam et al, 2010;Wartberg et al, 2016). En segundo lugar, a nivel de cribado, el punto de corte original (≥ 2) es el que presenta un mayor equilibrio entre los cuatro indicadores utilizados, con una sensibilidad del 74,4%, una especificidad del 96,4%, un VPP del 88,4% y un VPN del 91,1%.…”

“…A nivel de consistencia interna, la revisión de numerosos trabajos revela unos valores más bien discretos con índices α de Cronbach que en algunos casos no llegan al ,70 (Bertini et al, 2015;Knight, Sherritt, Shrier, Harris y Chang, 2002;Skogen, BØe, Knudsen y Hysing, 2013;Wartberg, Kriston, Diestelkamp, Arnaud y Thomasius, 2016). En cuanto a su capacidad de cribado, es posible señalar que el CRAFFT posee unas propiedades psicométricas adecuadas (Dhalla, Zumbo y Poole, 2011) con unos índices de sensibilidad y especificidad, por lo general, elevados (Gryczynski et al, 2015;Kandemir et al, 2015;Knight, Sherritt, Harris, Gates y Chang, 2003;Pereira, Schram y Azevedo, 2016).…”

An Item Response Theory Analysis of the Korean Version of the CRAFFT Scale for Alcohol Use Among Adolescents in Korea

“…To serve as a valid screening tool for alcohol use problems in adolescents in different parts of the world, some adjustments have been necessary. For example, the Argentine [11], French [12], Norwegian [13], Turkish [14], and Korean versions of the CRAFFT [15] have been evaluated for sensitivity and specificity, showing that there were variations in sensitivity and specificity, which suggests that these results were affected by each country's own societal and cultural factors. As for the Korean version of the CRAFFT, the question related to "Car" ("have you ever ridden in a car driven by someone including yourself who was high or had been using alcohol or drugs?")…”

“…Similarly, in the Argentinian version of the CRAFFT, questions related to "Car" and "Alone" (e.g., "Do you ever use alcohol or drugs while you are by yourself, or alone?") had little influence on screening for alcohol use problems [11]. Adaptation of the CRAFFT to each country's unique circumstances is necessary to ensure that the measure is culturally and developmentally appropriate for its adolescent population [14].…”

“…These aforementioned studies that validated different language versions of the CRAFFT used classical test theory (CTT), which involves examining reliability and factor structure [11,12,14,15], whereas there is a lack of studies conducted to validate the CRAFFT using item response theory (IRT) [13]. To validate an instrument, IRT has some advantages in overcoming the limitations of CTT, for which reason this study used IRT.…”
