An Interpretative Phenomenological Study of the Experiences and Value of Flow Transcranial Direct Current Stimulation (tDCS) and Behaviour Therapy Training Software Used at Home for Specialist Perinatal Mental Health Service and Maternal Loss Psychology Service Patients with Depression

Background: Flow FL-100 is a transcranial direct current stimulation (tDCS) device designed to alleviate symptoms of depression, offering an alternative to psychotherapy and pharmacological interventions. The Flow treatment also includes access to wellbeing behaviour therapy training delivered through a software application. This study examines the user experience and perceived value of Flow among individuals receiving care from a Specialist Perinatal Mental Health Service and the Maternal Loss Psychology Service. Methods: Qualitative methods, including semi-structured interviews, were employed to explore participants’ experience over a six-week period. Interpretative Phenomenological Analysis (IPA) was utilised to analyse the data. The study recruited thirteen female participants aged between 29 and 40 all diagnosed with depression, with five having experienced maternal loss and eight reporting postpartum depression. Results: Participants reported positive experiences with Flow, highlighting its user-friendly interface, accessibility, and the availability of visual instructions. Most participants adhered to the treatment protocol, but challenges such as life-style restrictions were noted. Participants appreciated a non-medication treatment alternative and reported improvements in depressive symptoms, mood, sleep quality, and overall well-being. Discussion: The findings underscore the potential of Flow as a non-pharmacological intervention for depression. Individual variability in treatment response and engagement with the app’s training emphasise the need for personalised approaches. Further research is warranted to explore the long-term experience and value of Flow treatment.
