Quasi-experimental study on the effectiveness of psychoanalysis, long-term and short-term psychotherapy on psychiatric symptoms, work ability and functional capacity during a 5-year follow-up

Psychodynamic treatment of depression

Findings reviewed in this article show that PT should be included in treatment guidelines for depression. BPT in particular has been found to be superior to control conditions, equally effective as other active psychological treatments, with treatment effects that are often maintained in the long run, conferring resistance to relapse. Moreover, BPT is as effective as pharmacotherapy in the acute treatment of mild to moderate depression, and, either as monotherapy or combined with medication, BPT is associated with better long-term outcome compared with pharmacotherapy alone. PT is accepted by many depressed patients as a viable and preferred treatment. Furthermore, LTPT and PA have shown promise in treating patients with complex psychological disorders characterized by mood problems, often with comorbid personality problems. Finally, although studies suggest that effects of PT may be achieved somewhat slower compared with other forms of psychotherapy as well as medication in the acute treatment of depression, LTPT appears to be more clinically effective and perhaps more cost effective in the long run, particularly for chronically depressed patients. As noted, these conclusions need to be interpreted within the context of important limitations. Compared with other treatments, the evidence base for PT in depression remains relatively small, despite a respectable research tradition supporting psychodynamic assumptions with regard to the causation of depression. Moreover, and perhaps most importantly, although more studies now include longer follow-up assessments, our knowledge about the long-term effects of so-called evidence-based treatments of depression remains sketchy at best. In this context, the growing evidence for the efficacy and effectiveness of LTPT is promising. Overall, it is clear that the future of the treatment of depression may lie in a combined disorder- and person-centered, tailored-made approach, which takes into account, particularly in chronic depression, the broader interpersonal context and life history of the individual. It is clear that psychodynamic therapies have an important role to play in this respect.

Use of auxiliary psychiatric treatment during a 5-year follow-up among patients receiving short- or long-term psychotherapy

BACKGROUND

The need for treatment is, despite of its obvious usefulness, a scarcely used measure of effectiveness in psychotherapy trials. This study considers changes in the need for auxiliary psychiatric treatment after starting short- and long-term psychotherapy and psychoanalysis.

METHODS

Altogether 326 psychiatric outpatients with mood or anxiety disorder were randomly assigned to solution-focused therapy (SFT), short-term psychodynamic psychotherapy (SPP), or long-term psychodynamic psychotherapy (LPP) while 41 self-selected patients were allocated to psychoanalysis (PA). The patients were followed for 5 years from start of treatment. Outcome measures were use of auxiliary psychotherapy, psychotropic medication, and hospitalization for mental reasons.

RESULTS

About 60% of the patients used auxiliary treatment during the follow-up. It was most common in the short-term therapy groups and its incidence was highest during the first year after the start of therapy. The average numbers of all therapy sessions among patients starting the therapy were 60, 70, 240, and 670 in SFT, SPP, LPP, and PA, respectively, whereas the corresponding average numbers of study therapy sessions alone were 10, 19, 232, and 646. Over 50% of the patients receiving short-term therapy received on average 4-6 times more therapy sessions than initially assigned.

LIMITATIONS

Post-randomization withdrawal was uneven.

CONCLUSIONS

Auxiliary treatment is usual among patients receiving short- and long-term therapies, and apparently becomes common shortly after the start of treatment. Auxiliary treatment can be used as an outcome measure indicating the need for treatment, should be monitored clinically and considered when interpreting the results of effectiveness studies.
