“…Although depressive rumination may result in a sense of increased insight into one's problems, feelings, and symptoms (Lyubomirsky & Nolen-Hoeksema, 1993;Papageorgiou & Wells, 2001;Watkins & Moulds, 2005), depressive rumination has also been found to exacerbate existing levels of negative mood (Lavender & Watkins, 2004;Watkins & Teasdale, 2001), increase negative thinking (Lyubomirsky & Nolen-Hoeksema, 1995), and impair concentration and central executive functioning (Lyubomirsky, Kasri, & Zehm, 2003;Watkins & Brown, 2002). The presence of depressive rumination has been well established in depression (Riso et al, 2003), but also in a range of other axis I disorders, including bipolar disorder (Gruber, Eidelman, Johnson, Smith, & Harvey, 2011), alcohol use disorders (Caselli, Bortolai, Leoni, Rovetto, & Spada, 2008), obsessive-compulsive disorder (Wahl, Ertle, Bohne, Zurowski, & Kordon, 2011), post-traumatic stress disorder (Ehring, Frank, & Ehlers, 2008), and schizophrenia (Badcock, Paulik, & Maybery, 2011).…”
