However, a short-term (5 months) MBT program has recently been developed. No studies have investigated how MBT therapists experience the shift towards conducting short-term MBT for BPD. Objective: The objective of this study was to explore therapist experiences with conducting short-term MBT for outpatients with BPD in the Danish mental health services. Methods: Semi-structured qualitative interviews were conducted with seven therapists about their experiences with short-term MBT after a one-year pilot phase. The interviews were verbatim transcribed and analyzed using thematic analysis. Results: The following four major themes from the therapists’ experiences with short-term MBT were found in the qualitative analysis: 1) The longer the better, 2) Change processes can be intellectual or experiential, 3) Short-term therapy is hard work, and 4) Termination is more challenging in short-term MBT Conclusions: Most therapists were overall reluctant towards changing from long-term to short-term MBT. These therapist experiences could inform implementation of short-term MBT in mental health settings in the future.
