Our Research

In our current project, we investigate an interpersonal form of rumination known as co-rumination. Co-rumination is a process where friends repeatedly discuss their problems and dwell on their negative feelings. While both co-rumination and rumination are associated with higher depressive and anxiety symptoms, only co-rumination is linked to better friendship quality.

Research suggests that underlying positive beliefs about the benefits of rumination (e.g. the belief that rumination may help the individual find answers to their depression) and negative beliefs about the drawbacks of rumination (e.g. the belief that rumination is uncontrollable) may maintain the ruminative process. Likewise, we hypothesize that people hold similar positive and negative beliefs about co-rumination, affecting the likelihood, frequency, and intensity that they engage in this process.

During this project, we are developing a scale that assesses people’s beliefs about co-rumination. We plan to use this scale to study how these beliefs influence co-rumination and its related outcomes, including depression and anxiety.
