The psychometric characteristics of the Children's Depression Inventory, CDI (Kovacs, 1992) in a sample of 1705 participants (792 boys and 913 girls) and a clinical sample of 102 participants (42 boys and 60 girls) between 10 and 18 years old are presented. Reliability coefficients range, for both samples, from .82 (test) to .84 (retest) in the community sample, and .85 (test, clinical sample); test-retest reliability is .81 in the community sample. The mean scores are similar to other Spanish and English ones. Girls score higher than boys. The cut-off point that best differentiates between depressive and community participants is 19, with a sensitivity of 94.7%, a specificity of 95.6%, a positive predictive value of .90, and a negative predictive value of .98. Se presentan las propiedades psicométricas del Children's Depresión Inventory, CDI (Kovacs, 1992) en una muestra comunitaria de 1.705 participantes (792 chicos y 913 chicas) y en una muestra clínica de 102 participantes (42 chicos y 60 chicas) con edades comprendidas entre los 10 y los 18 años. La fiabilidad del CDI es elevada para ambas muestras: consistencia interna entre 0.82 (test) y 0.84 (retest) en muestra comunitaria, y de 0.85 (test, muestra clínica); la correlación test-retest es de 0.81 en la muestra comunitaria. Las puntuaciones medias son similares a las encontradas en otras muestras españolas y anglosajonas. En general, las mujeres obtienen puntuaciones superiores a los varones. El punto de corte que mejor discrimina entre los participantes diagnosticados de depresión y el grupo comunitario de contraste es 19, con una sensibilidad de 94.7%, una especificidad del 95.6%, un valor predictivo positivo de 0.90 y un valor predictivo negativo de 0.98.
