“…A recent report for insomnia (Bastien, Morin, Ouellet, Blais, & Bouchard, 2004) and another for depression (Lockwood, Page, & Conroy-Hiller, 2004) found group CBT to be approximately equivalent to individual CBT. An additional study found individual CBT to be more effective than group CBT for bulimia nervosa (Nevonen & Broberg, 2006), and another study found individual CBT to be more effective than group CBT for obsessions without compulsions (O'Connor et al, 2005). However, there is support for general CBT-based early interventions across disorders, such as for panic disorder, (Nuthall & Townend, 2007), major depressive disorder (Quiring, Monroe, Simons, & Thase, 2002), and trauma (Ehlers & Clark, 2003) for example.…”
