Aish, A.-M. & Wasserman, D. (2001). Does Beck's Hopelessness Scale really measure several components? Psychological Medicine31, 367–372. The analyses published in this Brief Communication are based on the material collected in Sweden in Stockholm (202) Cases and in Umeå (122 cases).

In the final version, following the reviewer's comments, when the article was shortened and accepted for publication as a Brief Communication, the name of one of the authors, Ellionor Salander Renberg, was omitted due to an oversight. The authors wish to make it clear that this Brief Communication had three authors. They also acknowledge Ellionor Salander Renberg for giving written approval to use the cases collected in Umeå, before commencement of the analyses.
