The efficacy of short-term psychodynamic
psychotherapy for depression: a summary
of recent findings
DOI: 10.1111/j.1600-0447.2009.01526.x
To the editor:
We commend Malhi et al. (1) and this journal for publishing
excellent clinical practice recommendations for depression. We
write to highlight new findings supporting Short-Term Psy-
chodynamic Psychotherapy (STPP) for depression which, using
the authorsÕcriteria requiring a systematic review of random-
ized controlled trials (1), may result in increasing the level of
evidence for this treatment.
We recently published a meta-analysis of group and
individual STPP for depression (2), including 23 studies
totaling 1365 patients. We found STPP resulted in large
symptom reductions (d=1.34), that were maintained until
1-year follow-up. STPP was found superior to controls
(d= 0.69), but somewhat less efficacious than other psycho-
therapies at post-treatment (d=)0.30). However, we found
no significant differences at 3- and 12-month follow-up
(d=)0.05; d=)0.29). Individual STPP (d= 1.43) was
more effective than group STPP (d= 0.83), and as effective
as other individual psychotherapies at post-treatment
(d=)0.19), 3- and 12-month follow-up (d=)0.05 and
)0.31; all non-significant). These findings add to the evidence-
base of STPP for depression and may result in an increase to
the highest level of evidence according to the criteria used by
Malhi et al. (1).
Furthermore, STPP has been found effective at reducing
symptoms in treatment resistant depression (3) and personal-
ity-disordered depressed patients (4). A recent review (5) found
STPP producing robust and persistent symptom-reducing
effects for personality-disordered patients (d= 0.97). These
findings render STPP a treatment of choice for these depressed
populations that are frequently non-responsive to initial
depression treatment.

We welcome the brief correspondence by Abbass and Driessen
(1) that provides a summary of recent research findings in
relation to the efficacy of Short-Term Psychodynamic Psycho-
therapy (STPP) for the treatment of depression. The findings
from the cited meta-analysis (2) endorse our position that
psychological strategies should be given greater consideration
(3). Whether in the context of combination treatment, where
short-term therapy supplements effective medication or is
delivered alone, the benefits of such therapy are implicated in
the longer-term, especially when the acute phase of depression is
targeted (4, 5).
The comparative efficacy of STPP to other psychotherapies
including cognitive behaviour therapy, cognitive therapy,
behaviour therapy, supportive therapy, non-directive counsel-
ing, and art therapy (2, 6, 7) is interesting and reflects clinical
experience with respect to the treatment of depression in that
Ôdoing something is generally better than doing nothingÕ, and as
regards doing something, Ômost interventions when compared
over a short period of time are broadly equal in terms of
effectivenessÕ(8). That is not to say there aren’t genuine
differences between different interventions, but that identifying
specificity or partitioning effect often proves difficult. This is
particularly so in randomized controlled trials, which are
usually powered to demonstrate a difference from placebo but
non-inferiority to an active comparator. Interestingly, this
applies to all therapeutic modalities and includes comparisons
conducted within the ever-expanding pharmacotherapeutic
armamentarium.
With respect to the comment from Abbass and Driessen
(1), it is further interesting to note that individual therapy

appears to be more effective than that delivered in a group
setting. This suggests that perhaps the therapeutic relationship
which is presumably more readily achieved in a setting with
exclusive interaction, is perhaps key. Overall these recent
findings could elevate the status of STPP to first-line
administration in particular for acute ⁄short-term manage-
ment of major depression. However, generalization to more
difficult populations in particular, where there has been
partial or no response to initial treatments, is more conten-
tious and further research is still perhaps needed before a
definitive conclusion can be made.
