Common misconceptions about cognitive mediation of treatment change: A commentary to

The article by Richard J. Longmore and Michael Worrell [Clinical Psychology Review, Volume 27, 2007, pp. 173–187] reviews a selection of studies showing no significant difference between treatment conditions that include formal cognitive restructuring techniques and other behavioral treatment modalities that do not include techniques to directly challenge cognitions. Based on this literature, Longmore and Worrell question the validity of the cognitive behavioral treatment model and argue that changes in symptoms are not mediated by changes in cognitions. Longmore and Worrellʹs arguments are based on common misconceptions about mediation models of treatment change. This commentary discusses and clarifies these misconceptions.
