The Spence Children's Anxiety Scale is an instrument widely applied in the assessment of the most common anxiety disorders in children and adolescents. This study examines its psychometric properties and the factorial structure in a large community sample of Spanish-speaking adolescents (N = 1,374) aged 13 to 17 years. The scale demonstrated strong internal consistency and good convergent and discriminant validity. Factor analysis confirmed the 6-factor original model, providing a good fit of the data for the Spanish sample. The good psychometric properties support its use by clinicians and researchers, adding evidence to the international empirical support for this measure.
