RETRACTED ARTICLE: Bright light treatment as mono-therapy of non-seasonal depression for 28 adolescents

Abstract

We, the Editors and Publisher of the International Journal of Psychiatry in Clinical Practice, have retracted the following article:

Helmut Niederhofer & Kai von Klitzing (2012) Bright light treatment as mono therapy of non -seasonal depression for 28 adolescents, International Journal of Psychiatry in Clinical Practice, 16:3, 233-237, DOI: 10.3109/13651501.2011.625123.

Since publication, concerns have been raised that this is a redundant publication. Upon investigation, it was discovered that the article is near identical and reports the same results to a previously published article:

Helmut Niederhofer & Kai von Klitzing, (2011) Bright Light Treatment as Add-On Therapy for Depression in 28 Adolescents: A Randomised Trial, 13:6, DOI: 10.4088/PCC.11m01194.

When consulted, the author claimed that the two studies provide different results. We requested the original data for both articles from the author, but the author was unable to provide this. The Editor-in-Chief confirmed that the values presented in the tables and figures are the same and therefore the two papers cannot present different results. The author was informed about the decision to retract the article.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
