A factorial analysis type studio for validation of instrument was performed. Among the main result is observed that the guide shows acceptable global values (Cronbach’s alpha of .86 and explained variance of 51.2%), and slightly lower for each of the areas that the instrument evaluates (Cronbach’s alpha of .61 to 76). It’s suggested to use scale in the whole (global) way, but don’t in the individual use of subscales.
