A total of 1,514 participants residing in Medellín, Barranquilla and Pasto were surveyed. Rasch analysis of adjustment of response categories, adjustment of items and people, differential functioning of the items, dimensionality and local independence of the items and reliability were carried out. The main results indicated that the response format conforms to the Linacre function optimization requirements. All the items show Infit and Outfit means square in the expected range. The scale is one-dimensional and Wright’s reliability was estimated at 0.962.
