The exploration phase might be drawing to a close, but the psychometric evaluation of an instrument is merely starting. The process of performing exploratory factor analysis is usually seeking to answer the question of whether a given set of items forms a coherent factor (or several factors). After we decide whether this is likely, evaluating how well those constructs are measured is important. Along the way, we can also ask whether the factor that is being examined needs all the items in order to be measured effectively.
