Resumen
Valorar la calidad métrica de la versión abreviada de 10 ítems del Cocaine Craving Questionnaire-Now (CCQ-N-10) en su adaptación al castellano. La muestra está constituida por 63 personas que inician tratamiento por abuso (n=23) o dependencia de cocaína (n=40) según criterios DSM-IV. Se administró una batería de instrumentos entre los cuales se hallan la versión extendida de 45 ítems del Cocaine Craving Questionnaire-Now (CCQ-N-45) de la que se extrae la versión abreviada, la Cocaine Craving Scale (CCS), una Escala Visual-Analógica del craving percibido (EVA), la Entrevista de Severidad de la Dependencia (SDS) y la Impresión Clínica Psiquiátrica (ICP). Todos los instrumentos muestran una alta consistencia interna (alpha de Cronbach para CCQ-N-10=0,95; CCQ-N-45=0,88; SDS=0,79 y CCS=0,93) y un Coeficiente de Correlación Intraclase para el test-retest del CCQN-10 de 0,59 (p<0,001). El análisis factorial del CCQ-N-10 (KMO=0,85) muestra unidimensionalidad llegando a explicar el 68,6% de la varianza, con saturaciones entre 0,64 y 0,92. Un análisis factorial confirmatorio ratifica la unidimensionalidad observada (CFI=0,91; SRMR=0,06). El CCQ-N-10 explica un 86,6% de la varianza de la versión extendida (CCQ-N-45) y presenta validez convergente con otros constructos afines (correlación CCQ-CCS r=0,64; CCQ-EVA r=0,65; CCQ-SDS r=0,53; y CCQ-ICP r=0,50). Se observan diferencias en las puntuaciones del CCQN-10 (F(1;60,6)=7,16; p=0,010) cuando es administrado a personas con diagnóstico de abuso (M=2,76) respecto a las personas diagnosticadas de dependencia (M=3,62). Conclusiones: La adaptación española del CCQ-N-10 presenta adecuación métrica y puede considerarse como un instrumento oportuno para su utilización en dependencia de cocaína.
To assess the metric properties of the abridged, 10-item version of the Cocaine Craving Questionnaire-Now (CCQ-N-10) in its Spanish adaptation. The sample consists of 63 people beginning treatment for cocaine-abuse (n=23) or dependence (n=40) disorders according to DSM-IV criteria. Participants completed an assessment battery that included the extended, 45-item version of the Cocaine Craving Questionnaire (CCQ-N-45) –in which the CCQ-N-10 is embedded–, the Cocaine Craving Scale (CCS), a Visual Analog Craving Scale (VAS), the Severity of Dependence Scale (SDS), and the Clinical Psychiatric Impression (CPI). Cronbach’s values for the CCQ-N-10, CCQ-N-45, SDS and CCS scales were 0.95, 0.88, 0.79 and 0.93, respectively, indicating that all instruments show high internal consistency. Test-retest reliability for the CCQ-N-10 was fair (Intraclass Correlation Coefficient=0.59; p<0.001). A factor analysis of the CCQ-N-10 (KMO=0.85) shows a one-factor structure explaining 68.6% of the variance, with factor loadings ranging from 0.64 to 0.92. Confirmatory factor analysis supports the unidimensionality of the scale (CF =0.91; SRMR=0.06). The CCQ-N-10 explains 86.6% of the variance accounted for by the CCQ-N extended version (CCQ-N-45) and shows convergent validity with related measures such as the CCS (r=0.64, p<0.001), VAS (r=0.65, p<0.001), SDS (r=0.53, p<0.001) and CPI (r=0.50, p<0.001). Persons fulfilling criteria for cocaine-dependence disorder, compared to those who present cocaine abuse, show higher CCQ-N-10 scores (F(1;60.6)=7.16, p=0.010). Conclusions: The Spanish adaptation of the CCQ-N-10 shows metric adequacy, and can be considered as a suitable assessment instrument in relation to cocaineuse disorders.
