Birth Attitudies Survey

1. By using the average of these scores(i.e agree, disagree, and so on..),, is it would be realistic to valiadate this survey ?

2. How could they identify the groupings by using the correlation structure of the these categogies avarage scores ? I think, sometimes it is difficult to distinguish among agree, strongly agree and mild agree ?

3. Besides these two set of questions, is it possible to add some quantitative measurements ? I think, that quantitative measurements would be beneficial to make a concrete decision about the safety of child-birth.
