Can Beck's theory of depression and the response style theory be integrated?

There are obvious similarities between the cognitive constructs of A. T. Beck's (1976) cognitive theory and the response style theory (S. Nolen-Hoeksema & J. Morrow, 1991). Different propositions of J. A. Ciesla and J. E. Roberts (2007) and S. Lyubomirsky and S. Nolen-Hoeksema (1993, 1995) concerning associations of 2 response styles, brooding and reflection, with constructs of Beck's cognitive theory (schemata, cognitive errors, cognitive triad, automatic thoughts) were tested. Model comparisons were based on a 4-week study in which 397 participants completed self-report instruments at 2 time points. A model allowing schemata to influence brooding and reflection that influence the other cognitive variables of Beck's cognitive theory fits the data better than the other integrated models. However, although schemata were significant predictors of both response styles, neither response style did significantly predict other cognitive variables. A comparison of the integrated model with Beck's original cognitive theory revealed that Beck's original theory fits the data better than the integrated model, whereas both models explain about the same amount of variance. Thus, an integration of Beck's theory and the response style theory are not supported.
