Transdiagnostic treatments are one approach with potential to increase access to treatment for people with anxiety disorders and depression (Barlow, Allen, & Choate, 2004; Craske et al., 2009; Wilamowska et al., 2010). Interest in this approach reflects a growing recognition that the internalising disorders are highly co-morbid, share similar symptoms and respond to similar treatments (Goldberg, 2010). Emotion regulation strategies are recently consider as the transdiagnostic factors that have important role in the development or maintenance of psychopathology specially in depressive and anxiety disorders (Aldao & Nolen- Hoeksima, 2010; Ehring & Watkins, 2008; Norton, Hayes, & Springer, 2008).
