A Validation Study of the Korean Child Behavior Checklist 1.5-5 in the Diagnosis of Autism Spectrum Disorder and Non-Autism Spectrum Disorder

OBJECTIVES: The purpose of this study was to analyze the discriminant validity and the clinical cut off scores of the Child Behavior Checklist 1.5-5 (CBCL 1.5-5) in the diagnosis of autism spectrum disorder (ASD) and non-ASD. METHODS: In total, 104 ASD and 441 non-ASD infants were included in the study. T-test, discriminant analysis, receiver operating characteristic (ROC) curve analysis, and odds ratio analysis were performed on the data. RESULTS: The discriminant validity was confirmed by mean differences and discriminant analysis on the subscales of Emotionally reactive, Somatic complaints, Withdrawn, Sleep problems, Attention problems, Aggressive behavior, Internalizing problems, Externalizing problems, and Total problems, along with the Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales between the two groups. ROC analysis showed that the following subscales significantly separated ASD from normal infants: Emotionally reactive, Somatic complaints, Withdrawn, Sleep problems, Attention problems, Aggressive behavior, Internalizing problems, Externalizing problems, Total problems, and DSM pervasive developmental problems. Moreover, the clinical cut off score criteria adopted in the Korean-CBCL 1.5-5 were shown to be valid for the subscales Withdrawn, Internalizing problems, Externalizing problems, Total problems, and DSM pervasive developmental problems. CONCLUSION: The subscales of Withdrawn, Internalizing problems, Externalizing problems, Total problems, and DSM pervasive developmental problems significantly discriminated infants with ASD.

Consistencia interna y validez de criterio de la versión mexicana del Child Behavior Checklist 1. 5-5 (CBCL/1.5-5) / Internal consistency and criterion validity and reliability of the Mexican Version of the Child Behavior Checklist 1. 5-5 (CBCL/1.5-5)

Objetivo: Investigar la consistencia interna y la validez de la versión mexicana de la lista de síntomas de niños de 1,5 a 5 años de edad del Child Behavior Checklist (CBCL/1.5-5) que mide la psicopatología más común en niños preescolares en el contexto clínico y epidemiológico. Pacientes y método: Diseño transversal, comparativo, en una muestra de 438 padres de 2 grupos: clínico-psiquiátrico (n = 62) y comunitario (n = 376). Se aplicó el instrumento CBCL/1,5-5 adaptado al lenguaje español coloquial mexicano. Para el análisis estadístico se utilizó el coeficiente alfa de Cronbach, prueba de Feldt y correlación de Pearson. Resultados: La consistencia interna para las subescalas fue elevada para problemas totales α = 0,95, internalizados α = 0,89, externalizados α = 0,91. El test-retest mediante el coeficiente de correlación intraclase fue mayor a 0,95 para las subescalas de problemas internalizados, externalizados y totales. La curva de Receiver Operating Characteristic, para el criterio de los grupos referido-clínicamente frente a no-referido para la escala total de problemas ≥ 24 resultó en un área bajo la curva 0,77, especificidad 0,73 y sensibilidad 0,70. Conclusiones: El CBCL/1,5-5/versión mexicana es un instrumento válido y confiable.

Objective: To investigate the validity and internal consistency of the Mexican version of the CBCL/1.5-5 that assesses the most common psychopathology in pre-school children in clinical and epidemiological settings. Patients and method: A total of 438 parents from two groups, clinical-psychiatric (N= 62) and community (N= 376) completed the CBCL/1.5-5/Mexican version. Results: The internal consistency was high for total problems α=0.95, and internalized α=0.89 and externalized α=0.91 subscales. The test re-test (one week) using the intraclass correlation coefficient (ICC) was ≥ 0.95 for the internalized, externalized, and total problems subscales. The ROC curve for the criterion status of clinically-referred vs. non-referred using the total problems scale ≥ 24 resulted in an AUC (area under curve) of 0.77, a specificity 0.73, and a sensitivity of 0.70. Conclusions: The CBCL/1.5-5/Mexican version is a reliable and valid tool.
