[On the present situation in psychotherapy and its implications - A critical analysis of the facts].

The currently dominating research paradigm in evidence-based medicine is expounded and discussed regarding the problems deduced from so-called empirically supported treatments (EST) in psychology and psychotherapy. Prevalent political and economic as well as ideological backgrounds influence the present dominance of the medical model in psychotherapy by implementing the randomized-controlled research design as the standard in the field. It has been demonstrated that randomized controlled trials (RCTs) are inadequate in psychotherapy research, not the least because of the high complexity of the psychotherapy and the relatively weak role of the treatment concept in the change process itself. All major meta-analyses show that the Dodo bird verdict is still alive, thereby demonstrating that the medical model in psychotherapy with its RCT paradigm cannot explain the equivalence paradox. The medical model is inappropriate, so that the contextual model is proposed as an alternative. Extensive process-outcome research is suggested as the only viable and reasonable way to identify highly complex interactions between the many factors regularly involved in change processes in psychotherapy.
