To the Editor: We have become aware that an article published in The Primary Care Companion for CNS Disorders (Niederhofer H, von Klitzing K. Bright light treatment as add-on therapy for depression in 28 adolescents: a randomized trial. Prim Care Companion CNS Disord. 2011;13(6):PCC.11m01194. https://doi.org/10.4088/PCC.11m01194) is nearly identical to and reports the same results as the article published in International Journal of Psychiatry in Clinical Practice (Niederhofer H, von Klitzing K. Bright light treatment as mono-therapy of non-seasonal depression for 28 adolescents. Int J Psychiatry Clin Pract. 2012;16(3):233–237. https://doi.org/10.3109/13651501.2011.625123).
