In the area of psychometric measurement of depression, the most comprehensive multidimensional instrument is the Clinical Analysis Questionnaire (CAQ). This self-report inventory is purported to measure some 28 normal and abnormal personality source traits. In particular, seven separate depression primaries are claimed to have a measurement basis in the CAQ.

In order to simplify interpretation of CAQ scores, it seems desirable to utilise a smaller number of more reliable superfactors wherever possible. The present investigation explores this iss..
