Aim: Aim of the present study was to examine an additional benefit of biofeedback sessions as an adjunct to an ongoing eight-week multimodal therapeutic hospital treatment for borderline patients.
Methods: 37 borderline patients were split to a study group participating in six biofeedback sessions and a control group participating in six relaxation session (imaginary journey by self-instruction) by cluster randomization. Self-observed tension before and after each session (VAS-scale), self-observed helpfulness of session for understanding symptoms (VAS-scale), clinical global impression (CGI) at start and end of study, assumed indication for relaxation session, self-harming behaviour and acute medication were measured. Differences of means and frequencies between the study groups were tested using t-tests and crosstabulation (2-tests).
Results: Ad-on biofeedback sessions do have a significant positive effect on relaxation and are significant more helpful for understanding ones own disorder. Patients in experimental group are able to reduce tension to a significant greater extent and experience sessions as more helpful then those in control group. Regarding clinical global impression, self-harming behaviour and acute medication no significant group effects were found, but tendencies in expected direction.
Conclusio: The present study showed positive effects of biofeedback sessions within the framework of therapeutic hospital treatment of borderline patients compared to a control group, namely regarding reduction of tension and estimated helpfulness of sessions.
