Las versiones breves de instrumentos de evaluación son controversiales pero representan un importante aliado para la práctica profesional por varios motivos; por ejemplo, cuando no se cuenta con los recursos y el tiempo suficiente para evaluar con un test completo, porque prescinden de ítems redundantes, reducen la fatiga, frustración y aburrimiento de responder repetidamente ítems muy parecidos2. Pero los procesos para obtener evidencias de validez de las versiones breves implican nuevos desafíos; es por ello que consideramos relevante el aporte de Guic, Galdames y Rebolledo para la evaluación de la discapacidad mediante la versión breve del Cuestionario Roland-Morris (RDQ, por sus siglas en inglés). Sin embargo, la obtención de evidencias de validez fue realizada omitiendo aspectos metodológicos importantes que pueden poner en discusión las conclusiones de los autores. En e...

The objective of this study was to analyze the psychometric properties of the Scale of Alteration of the Behavior in the School (SABS) in a sample of Peruvian children of 1º to 6º degree of elemental education, and to obtain evidences that support their use like instrument of screening for behavioural alterations (BA). One obtained an acceptable Reliability through method of internal consistency (alpha de Cronbach = 0.937), as well as evidence of internal structure of the test, factorial validity (two factors that explain 61.986% of variance) and of criterial validity. To these they say us results that the Scale of Alteration of the Behavior in the School (SABS) is an instrument valid and reliable to be used like method of valuation of behavioural alterations in students of 1.º to 6.º of primary education.

In this study the psychometric properties of State-Trait Depression Inventory (STDI) were analyzed in a sample of adults from metropolitan Lima, to obtain validity evidences that support its use both in the consulting and non-consulting population. Acceptable indicators of reliability were found through a method of internal consistency (Cronbach’s alpha), as well as content validity evidence, factorial validity and of criteria validity. Therefore, the STDI is a valid and reliable instrument to evaluate the affective component of depression.
