The objective of the study is to examine whether a combination of wake therapy, light therapy and sleep time stabilization as a supplement to standard treatment can reduce depressive symptoms in patients admitted at two psychiatric wards at Aarhus University Hospital, Risskov. Seventy-four patients will be randomized either to this intervention or to a control group receiving treatment as usual. Furthermore, it will be examined whether the duration of admission can be reduced in the intervention group. Finally, the aim is to identify predictors of good effect of the intervention.
