The aim of this article was to examine the evidence of family psychoeducation (FPE) for affective disorders. Evidence indicates that FPE can be an effective supplement to the standard treatment of patients with affective disorders. FPE can effectively reduce the patients' risk of relapse and reduce the burden experienced by the relatives. However, current studies are very heterogeneous and therefore difficult to compare. Up to this point the evidence regarding the effect of FPE on unipolar depression is still very sparse and further research is needed.
