Adaptación y validación española del Adolescent-Cannabis Problems Questionnaire (CPQ-A)

Abstract

Cannabis is a widely used substance among adolescents and young adults, but demand for help and treatment from this age group continues to be low. It is therefore essential to develop instruments especially designed for the early detection of problems associated with cannabis use in this population. The purpose of this work is to adapt and validate the CPQ-A (Adolescent Cannabis Problems Questionnaire) for its use as a screening instrument in Spanish population. The sample was made up of 144 young people (71.5% male) aged 16 to 20 (M = 17.12; SD = 1.17) who had used cannabis in the last month and were on some kind of study or training course at various educational institutions in Asturias (a region in northern Spain). Factor analysis of the CPQ-A in this sample provides evidence of a unidimensional structure, with a Cronbach's Alpha of 0.86 for the questionnaire. The evidence also shows that the instrument's convergent validity is good. The CPQ-A score permits discrimination between moderate and excessive cannabis users over the last month, is positively related to score on the CAST (Cannabis Abuse Screening Test), and presents adequate sensitivity and specificity for identifying cases of cannabis abuse and dependence according to the DSM IV-TR criteria. It is also sensitive to young people's degree of concern about cannabis use and the psychopathological effects associated with it. In accordance with the results obtained, the CPQ-A can be considered a useful screening tool for young cannabis users with problems.Key words: cannabis, marijuana, screening, psychometrics, young people.

El propósito de este trabajo es adaptar y validar en población española el CPQ-A (AdolescentCannabis Problems Questionnaire) como herramienta de screening. La muestra utilizada está formada por 144 jóvenes (71,4% chicos), con edades comprendidas entre 16 y 20 años (M = 17,12; M = 17,12; M DT = 1,17), que DT = 1,17), que DT habían consumido cannabis en el último mes, y que se encontraban cursando algún tipo de formación en diversos centros educativos de Asturias. El análisis factorial del CPQ-A en esta muestra apunta a una solución unidimensional, con un Alfa de Cronbach de 0,86 para el total del cuestionario. Las evidencias de validez convergente de la prueba son buenas. La puntuación en el CPQ-A permite discriminar entre consumidores de cannabis moderados y excesivos en el último mes, está positivamente relacionada con el CAST (Cannabis Abuse Screening Test) y presenta una sensibilidad y especificidad adecuadas para determinar casos de abuso y dependencia del cannabis según los criterios del DSM ...

Screening of cannabis-related problems among youth: the CPQ-A-S and CAST questionnaires

“…The CPQ-A-S was obtained from the Spanish version of CPQ-A [20], and content equivalence with the original version was guaranteed by following the guidelines of the International Test Commission [21]. The CPQ-A-S used a dichotomous response option (yes/no), as stipulated by the authors [11].…”

Psychometric study of an adolescent substance use scale

“…The scales to evaluate consumption in adolescents is their partial use in the evaluation of drugs whether (legal or illegal), focusing on personality features without dealing with certain problem behaviours (Camacho et al, 2013;Castellanos-Ryan, et al, 2013;Fernández-Artamendi et al, 2012;Robles-García et al,2014). For this purpose, this paper presents the psychometric study of a scale based on the ESTUDES (2008) Moreover, drug use has been associated with family problems due to arguments with parents or siblings, and socially, due to having been involved in a physical fight or having suffered or initiated physical aggression, making contextualized preventive intervention more necessary (UNODC, 2015).…”

The Influence of Cannabis and Alcohol Use on Sexuality: An Observational Study in Young People (18–30 Years)

“…⚜ Problems associated with cannabis were assessed through the Spanish version of the Cannabis Abuse Screening Test (CAST) [ 18 ], which consists of 6 items through which the most common problems associated with cannabis use are detected, by means of a Likert-type scale from 0 to 4 (0 = never; 4 = very often).…”
