Juggling thoughts and feelings: How do female patients with borderline symptomology and substance use disorder...

The aim of this study was to explore the experience of central psychological change processes for female patients with borderline symptomology and substance use disorder in mentalization-based treatment.

Semi-structured qualitative interviews on experiences from mentalization-based treatment with 13 participants were conducted. The interview material was analysed within a hermeneutical-phenomenological epistemology, with emphasis on researcher reflexivity.

The following themes regarding central psychological change processes were found: "by feeling the feeling," "by thinking things through," "by walking in your shoes to see myself" and "by stepping outside of own bad feelings in seeing you." Two of these themes dealt with intra-psychic modes of how to relate to own mind-states. First, they had a shift from avoiding emotions into tolerating emotions. Second, they discovered the ability to think mental states through. Two themes dealt with mental stances for dealing with interpersonal situations, where one mode included a self-reflective stance in difficult encounters, and the other mode entailed an empathic reflective stance by exploring others' intentionality.

The findings are in line with theoretical assumptions that increasing mentalizing capacity is a central change process for these patients. Furthermore, the findings demonstrate the complex interaction between different modes of mentalizing. Clinical or methodological significance of this article: The article explores change processes in manualized psychotherapy for patients with comorbid borderline personality disorder and substance use disorder, a focus which is not researched in the clinical literature. We claim that putting attention to this patient group and investigating their potential in psychotherapy is of clinical significance. Methodologically, this article utilizes thematic analyses within an epistemology following a specific procedure that is step based and transparent, thus it is of interest for qualitative researchers who also utilize thematic analyses.
