Abstract

AIMS:

To investigate the effectiveness of psychodynamic-interpersonal therapy (PIT) in a routine clinical practice setting.

METHODS:

Full pre-post data were available on 62 out of a total of 67 patients aged between 19 and 60 years. Patients were seen over a 52-month period (2001-2005) receiving a course of PIT therapy (mean number of sessions = 16.9, median number of sessions = 16). The outcomes were assessed using a range of outcome measures: the 32-item version of the Inventory of Interpersonal Problems (IIP-32), the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM), and the Beck Depression Inventory - Second Edition (BDI-II). Study data were benchmarked against comparative national and local data.

RESULTS:

There were significant pre-post reductions on all measures: IIP-32 effect size (ES) = 0.56; CORE-OM ES = 0.76; BDI-II ES = 0.76. Reliable and clinically significant change was achieved by 34% of clients on the BDI-II and by 40% of clients on the CORE-OM. Clients with high pre-therapy levels of interpersonal problems had poorer outcomes.

CONCLUSION:

Benchmarking our results against both national and local comparative data showed that our results were less favourable than those obtained where PIT had been used in efficacy trials, but were comparable with reports of other therapies (including cognitive behavioural therapy (CBT)) in routine practice settings. The results show that PIT can yield acceptable clinical outcomes, comparable to CBT in a routine care setting, within the context of current limitations of the practice-based evidence paradigm.
