title: A test of the cognitive content specificity hypothesis in depression and anxiety.
abstract: The present study tested the cognitive content specificity hypothesis (CCSH) to assess whether anxiety and depression can be differentiated on the basis of cognitive disturbance. One hundred and thirty five depressed participants were administered the Beck depression inventory (BDI), the Beck anxiety inventory (BAI), the automatic thoughts questionnaire (ATQ) and the anxious self-statements questionnaire (ASSQ). It was hypothesised that depressive cognitions would be specifically related to, and predictive of, depressive (but not anxiety) symptoms in a depressed sample. Conversely, it was predicted that anxiety cognitions would be specifically related to, and predictive of, anxiety (but not depressive) symptoms in a depressed sample. Results revealed that the ATQ was the sole predictor of the BDI and similarly, the ASSQ was the sole predictor of the BAI. These findings support the CCSH in depression and provide an integrative framework for a greater understanding of the relationship between anxiety and depression.
