Obstacles to a randomised controlled trial of intensive dynamic psychotherapy: an account of the New South Wales Section of Psychotherapy outcomes project. 
This paper examines the obstacles to a randomised controlled trial (RCT) of intensive dynamic psychotherapy (IDP) by reference to the fate of the New South Wales Section of Psychotherapy outcomes project.  Planning was complete and the final research protocol was about to be implemented when funding difficulties led to suspension of the project.  The opinions of the research subcommittee regarding the main obstacles to the ultimate success of the project are now analysed in the expectation that better research strategies will follow.  With hindsight, six of the eight members of the research subcommittee reported that the project was not feasible.  By choice of questionnaire items they identified the greatest threats to a successful trial as: standardisation of the procedures, termination at 24 months, the availability of funding and the choice of treatment procedures.  The most frequently volunteered concerns related to the enlistment and cooperation of the trial therapists (5), standardisation of the experimental therapy (3), probable shortfall in trial subjects (3) and the availability of funding (2).  The most powerful general obstacles to success of the project related to the standardisation of procedures and the failure to maintain sufficient cooperation of trial therapists.  The protocol required IDP therapists to terminate procedures at 24 months, which contradicted their usual practices and led to some alienation from the project.  Amendments to the protocol might improve the possibility of a successful trial.  However, one might also conclude that it is premature to attempt a naturalistic RCT of IDP.
