Retraction statement: Authentically leading groups: The mediating role of collective psychological capital and trust

The following article from the Journal of Organizational Behavior, Authentically leading groups: The mediating role of collective psychological capital and trust by Fred O. Walumbwa, Fred Luthans, James B. Avey and Adegoke Oke, published online on 1st September 2009 in Wiley Online Library ( www.wileyonlinelibrary.com ) and in Volume 32, Issue 1, January 2011, Pages 4‐24, has been retracted by the journal's Editor in Chief, Neal M. Ashkanasy, and John Wiley & Sons Ltd. The retraction is on the grounds of the authors' advice that they made an error in relation to the level of analysis used. As a result of this error, the authors incorrectly calculated key fit statistics. When correctly estimated, the fit statistics do not provide an acceptable level of support for the hypothesized model, rendering the authors' conclusions, as stated in the article, unsustainable.
