[Evidence of the effect of psychodynamic psychotherapy].

Evidence of the effect of psychodynamic psychotherapy (PDT) has been called into question. Thus, an updated review of the effect of short-term and long-term PDT (STPP and LTPP) for anxiety, depression and personality disorders seems necessary. A systematic search of randomized controlled studies of PDT published from January 2000 to May 2016 was conducted, and we found 57 single studies and 13 meta-analyses fulfilling the criteria for inclusion. The studies show that PDT has therapeutic efficacy and effectiveness matching other forms of psychotherapy. LTPP shows better effect than STPP in the treatment of complex psychiatric disorders and long-term depression.
