I am using the MLQ (Multifactor Leadership Questionnaire) in a study on (European) nonprofit leaders. Since self- and other-ratings differ from the norms provided by the MLQ manual, I would like to check if this may be related to the sample's nonprofit background. Could you let me know about any nonprofit norms, suggestions on where/how to search for them or values (means and SDs) you found in a study carried out with the MLQ in the nonprofit sector?
