Birth Attitudies Survey

1. Is the average taken for each bullet point or for each "attitude/belief" category? The latter seems weird since the questions in a category are quite different and it doesn't make sense to average their responses.

2. Is "correlation structure of the average scores" referring to the correlation among the 15 categories?

3. In what way do you judge validity? Is there a "gold standard" for a valid survey for attitudes?
