BackgroundFor the treatment of chronic pain, interdisciplinary treatment programs are recommended. Despite continuous adaptation and optimization of this cost- and time-intensive and comprehensive form of therapy, it is not successful in some patients. As personality disorders have an important influence on social interaction and behaviour, the aim of our study was to identify the possible impact of patients with personality disorders on group dynamics and to analyse the influence of group dynamics on individual therapy outcomes.MethodsWe conducted a prospective observational study in patients with chronic pain (N = 104) who participated in a 5-week interdisciplinary treatment program. The main outcome parameters were psychological state and pain intensity before and after the program.ResultsIn contrast to our clinical assumption, we found that neither the type nor the number of patients with personality accentuation or personality disorders had a clinically relevant influence on group dynamics and that even a negative group dynamic did not negatively influence the individual therapy outcome.DiscussionThis trial analysed the connection between group dynamics and therapy outcome of multimodal pain therapies in chronic pain patients considering the factor of personality disorders. Our data demonstrated that neither the type nor the number of patients with personality disorders had a clinically relevant influence on group dynamics and that even a negative group dynamic did not negatively influence the individual therapy outcome. Hence, clinicians should not be afraid to include patients with personality disorders in their treatment programs.Significance StatementThe study emphasizes that clinicians may include patients with personality disorders in multimodal pain treatment programs and groups, provided that the maintenance of a close therapeutic bond with the patient and within the interdisciplinary team is given.© 2024 European Pain Federation ‐ EFIC ®.
