Positive beliefs about rumination in depression-a replication and extension

Papageorgiou and Wells (2001) reported that positive beliefs about rumination were elevated in depressed patients, using the Positive Beliefs about Rumination Scale (PBRS). However, this study had a relatively small sample and there is a possibility that there were confounds within this measure between the severity of depressed mood and endorsement of beliefs. This study attempted to replicate these findings within a larger sample, and to extend these findings to recovered depressed patients, who are known to demonstrate elevated rumination. Furthermore, a version of the PBRS adapted to reduce confounds with mood state and valence was also used. Consistent with predictions, both currently depressed and recovered depressed patients had elevated scores on both the original and adapted PBRS compared to never-depressed controls. The present findings confirm that positive beliefs about rumination are genuinely associated with elevated levels of rumination in depression-prone groups and indicated that previous similar positive findings (Papageorgiou & Wells, 2001) were not the result of methodological confounds such as criteria contamination in the PBRS or small sample size.
