Where can I get norms and psychometric data (reliability/validity) for the DASS?
The psychometric properties of the DASS and normative data for the DASS are described in detail in the DASS manual (see FAQ4). Additional information is available through published articles (see FAQ5). Tip: When interpreting alpha coefficients (internal consistency), remember that alpha is strongly determined by the number of items in a test. The more items, the higher alpha will be. So it is not appropriate to compare alphas between tests that have different numbers of items.
