The Effect of the Number of Answer Choices on the Psychometric Properties of Stress Measurement in an Instrument Applied to Children
The main objective of this study was to use Item Response Theory (IRT) models to measure the effect exerted by the number of response options on the psychometric properties of a test measuring stress in children. In this study, we applied the 30-item Child Stress Perception Inventory (CSPI) scale to...

| description | The main objective of this study was to use Item Response Theory (IRT) models to measure the effect exerted by the number of response options on the psychometric properties of a test measuring stress in children. In this study, we applied the 30-item Child Stress Perception Inventory (CSPI) scale to 583 children; the items have different response alternatives (3, 5, or 7). We studied whether the scales measure the same trait and whether the alternatives that the same items possess are equivalent. As evidenceof validity, we present measurements that examine the internal structure of the instrument and its relationship with other variables. The result indicates that the three forms measure the same trait, but that there is no equivalency among the categories.The scale adjustment of 7 response alternatives is best; however, validity in relation to other variables is optimal for 5 response alternatives, which in addition, performs best in terms of reliability and information. |

El presente trabajo tiene como principal objetivo analizar mediante modelos de la Teoría de Respuesta al Ítem (TRI) el efecto que tiene el número de alternativas de respuesta sobre las propiedades psicométricas de un test que mide estrés infantil. En el presente estudio se aplicó la escala de “Percepción de Estrés para Niños” (IPEI) de 30 ítems a 583 niños, los ítems tenían diferentes alternativas de respuesta (3, 5 o 7). Se estudio si las escalas miden el mismo rasgo y si las alternativas que tienen las mismas etiquetas son equivalentes. Como evidencias de validez se presentan medidas que examinan la estructura interna del instrumento y su relación con otras variables. Los resultados indican que las tres escalas miden el mismo rasgo pero no existe equivalencia entre las categorías. El ajuste de escala de 7 alternativas de respuesta es mejor, sin embargo, la validez en relación con otras variables es óptima para 5 alternativas de respuesta, que además muestra el mejor comportamiento en términos de fiabilidad e información.
