ABSTRACT
Introducción. La lista de síntomas del niño CBCL/6-18 (Child Behavior Checklist) es el instrumento para evaluar psicopatología en niños y adolescentes más comúnmente utilizado en estudios clínicos y en numerosos estudios epidemiológicos. La última versión contiene subescalas orientadas al DSM. Objetivo. Determinar las propiedades psicométricas del CBCL/6-18 y desarrollar una versión mexicana fiable y válida. Método. Paidopsiquiatras y psicólogos adaptaron la versión en español del CBCL/6-18; una retraducción fue realizada por una persona bilingüe. Las discrepancias en la adaptación se resolvieron por consenso. El CBCL/6-18 se aplicó a niños de la población general y a pacientes de la consulta externa de un hospital psiquiátrico. La consistencia interna se evaluó con el coeficiente alfa de Cronbach; el test-retest a 1 semana se calculó por medio del coeficiente de correlación intraclase (CCI). Se realizó una curva receiver operating characteristic (ROC) para estimar un punto de corte que discriminara a los niños de la comunidad de referidos clínicamente. Las diferencias en los puntajes de la escala se estimaron con la prueba t de Student. Resultados. La versión mexicana del CBCL/6-18 mostró coeficientes de alpha de Cronbach: problemas internalizadores, 0,90; externalizadores, 0,94, y el total de problemas, 0,97. El CCI para el test-retest de la escala total fue de 0,97. Las puntuaciones de los niños de ambos grupos mostraron diferencias estadísticamente significativas. Conclusiones. Con estos resultados se puede concluir que la versión mexicana del CBCL/6-18 es un instrumento válido y confiable para usarse como instrumento de cribado
Introduction. The Child Behavior Checklist (CBCL/ 6-18) is the most commonly used parent-completed instrument that assesses child and adolescent psychopathology. It has been used in epidemiology and clinical studies. The last version contains DSM-oriented subscales. Objective. Investigate the psychometric properties of the CBCL/6-18 and develops a valid and reliable Mexican version. Method. Psychologists and child psychiatrists adapted the Spanish version of CBCL/6-18, and a back translation was done by a native English speaker. Discrepancies in the adaptation were solved by consensus. The checklist was applied to children in the community and to outpatients from a psychiatric children hospital. Reliability was evaluated by estimating internal consistency (Cronbach's alpha) on all scales: retest at one week was evaluated with intraclass correlation coefficients (ICC). A receiver operating characteristic (ROC) curve was performed to estimate a cut-off which correctly identified children from the clinically referred patients and children recruited in the community (non-referred). Mean differences for the groups were calculated with the Student's t test. Results. The Mexican version of the CBCL/6-18 showed that the Cronbach's alpha coefficient was 0.90 for internalizing problems, 0.94 for externalizing problems and 0.97 for the total problem scale. The ICC was 0.97 for the total problem scale. Significant differences were found between the mean score in broad band, narrow and the new DSM/oriented scales. Conclusions. The Mexican version of CBCL/6-18 is a reliable and valid screening instrument for clinical and epidemiologic use
