Leichsenring F, et al. – The study aimed to examine the comparative efficacy of long–term psychodynamic psychotherapy (LTPP) in complex mental disorders. Results suggest that LTPP is superior to less intensive forms of psychotherapy in complex mental disorders.
Methods
- The authors conducted a meta-analysis of controlled trials of LTPP fulfilling the following inclusion criteria: therapy lasting for at least a year or 50 sessions; active comparison conditions; prospective design; reliable and valid outcome measures; treatments terminated.
- Ten studies with 971 patients were included.
Results
- Between-group effect sizes in favour of LTPP compared with less intensive (lower dose) forms of psychotherapy ranged between 0.44 and 0.68.
