Abstract

Extensive comorbidity exists between anxiety and mood disorders (Noyes, 2001). Forms of negative repetitive thought, such as worry and rumination, have been considered unifying constructs of both disorders. Current research has examined the efficacy of mindfulness and self-management based therapies on depression and anxiety disorders (Kuyken, Byford, Taylor, Watkins, Holden, White et al., 2008; Wright, Barlow, Turner, & Bancroft, 2003), however, limited research has examined the facets of mindfulness and self-management in relation to the negative repetitive thought styles of worry and rumination. Examining these relationships will aid in identifying potential therapeutic mechanisms for negative repetitive thought patterns. Study 1 examined mindfulness and self-management, and their constituent facets, in relation to rumination and worry in an undergraduate sample, and Study 2 examined the relationships between these constructs in a clinical sample. As expected, worry was highly related to rumination, and mindfulness was highly related to self-management in both samples. Results from these two studies also revealed that mindfulness, unlike self-management, is independently related to both worry and rumination. In terms of the individual facets of mindfulness, only acceptance without judgment was significantly related to worry and rumination in both samples. These results, and their implications, are discussed.
