‘My dad was like “it's your brain, what are you doing?”’: Participant experiences of repetitive transcranial magnetic stimulation treatment in severe enduring anorexia nervosa

Objective: Repetitive transcranial magnetic stimulation (rTMS) is a promising emerging treatment for anorexia nervosa (AN). However, to date, patients' views and experiences of this treatment have not been fully explored. To assess these, we integrated a qualitative study into a feasibility randomised controlled trial of rTMS in individuals with severe enduring AN. Method: Twenty-nine (of 34) trial participants contributed to this study. Semi-structured interviews were conducted 3-months following the completion of rTMS treatment (4-months post-randomisation), prior to unblinding. Transcripts were analysed using content analysis. Results: rTMS was deemed an acceptable but time-consuming treatment. Many emphasised how their lives had changed to some extent during, but mainly after treatment by making them more positive, open-minded, flexible and willing to try new things in relation to their AN and other aspects of their lives. Conclusions: These qualitative data will be valuable in shaping participant information, recruitment and planning of future large-scale trials of rTMS in AN.
