The weirdness of having a bunch of other minds like yours in the room: The lived experiences of mentalization-based therapy for borderline personality disorder.

OBJECTIVES

Studies of lived experiences are important for improving treatment effectiveness, but most studies of mentalization-based therapy (MBT) are quantitative. This qualitative study aimed to better understand service users' lived experiences of MBT, including their experiences of change.

DESIGN

This is a qualitative study that used one-to-one semi-structured interviews.

METHOD

Semi-structured interviews were conducted with eight MBT service users recruited via four NHS trusts. Interviews were analysed using interpretative phenomenological analysis (IPA).

FINDINGS

Three superordinate themes were identified: being borderline, being in the group, and being on a journey. 'Experiences of diagnosis' and 'the group' are salient topics in the lived experiences of service users' during the MBT journey, as is the nature/type of 'change' that can create symptom reduction albeit alongside a negative felt experience.

CONCLUSION

Our research aligns with current thought regarding the complexity and challenges of treating BPD via psychotherapy and adds a further dimension, that of experiencing MBT and changes during therapy. The participants' experiences of BPD and of experiencing MBT are discussed.

PRACTITIONER POINTS

Therapists are observant of how each client gives meaning to their experience of diagnosis, the group, and change, particularly since the experience of recovery is not all positive. Service users' emerging and ongoing construction of their experience of diagnosis is closely monitored and additional appropriate strategies implemented where necessary. The impact of joining MBT, especially the group, becomes a process for formal regular review. Therapists undertake an in-depth exploration of service users' felt experiences to capture less quantifiable dimensions of change.
