Suppose you are trying to create (i.e., measure) a construct using a 12-item scale. Factor analysis result shows that there are three underlying dimensions (i.e., 3 components/factors). However, your goal is to ignore the factor analysis result and combine the 12 items into one construct. Come up with an example of your own and explain 1 advantage and 1 disadvantage of combining them into one component.
