The Structure of the Clinical Analysis Questionnaire and Depression Symptomatology

The purpose of this study was to assess the conceptual distinctions among seven depression factors contained in the Clinical Analysis Questionnaire. This assessment was done by factor analyzing a representative pool of 62 items from existing depression measures and 56 CAQ subscale marker variables. The results showed that the majority of the 28 CAQ factors as defined by the marker variables can be sustained following procedures used previously by Cattell. However, the results pertaining to the depression factors indicate that revisions of the CAQ at the item level appear necessary for distinguishing the CAQ depression scales.
