‘I can do this’: a qualitative exploration of acceptability and experiences of a physical activity behaviour change intervention in people with multiple sclerosis in the UK

Abstract

ObjectivesThe purpose of this study was to explore the experiences of people with multiple sclerosis (MS) who participated in iStep-MS, a feasibility randomised controlled trial of a behaviour change intervention that aimed to increase physical activity and reduce sedentary behaviour.DesignA qualitative approach was undertaken embedded in the feasibility randomised controlled trial. One-to-one semi-structured interviews were conducted and analysed using Framework analysis.SettingParticipants were recruited from a single MS therapy centre in the southeast of England, UK.ParticipantsSixty people with MS were randomly allocated in a 1:1 ratio to the intervention or usual care. Following a purposive sampling strategy, 15 participants from the intervention arm undertook 1:1 semi-structured interviews.InterventionsThe iStep-MS intervention consisted of four therapist-led sessions over 12 weeks, supported by a handbook and pedometer.ResultsThree themes were identified from the data.“I can do this”: developing competence in physical activityhighlights the enhanced physical activity confidence gained through goal setting and accomplishment. “I felt valued”: the nurturing cultureprovides an overview of the supportive and non-judgemental environment created by the programme structure and therapeutic relationship. Finally, “What can I do?”: empowered enactmentdescribes the transition from the supported iStep-MS intervention to intrinsically motivated physical activity enactment.ConclusionsOverall, this study supports the acceptability of the iStep-MS intervention and identified key areas that supported participants to be physically active.Trial registration numberISRCTN15343862.

Pedometers, the frustrating motivators: a qualitative investigation of users’ experiences of the Yamax SW-200 among people with multiple sclerosis

“…Comprehensive details of the design and outcomes of the iStep-MS trial are described elsewhere [21,24]. Briefly, sixty people with MS were recruited from a single MS Therapy Centre in southeast England and the MS Society UK website and randomly allocated to the intervention or usual care group following baseline assessment in a 1:1 ratio.…”

Experiences of fatigued persons with multiple sclerosis with multimodal agility-based exercise training and the ReFEx study protocol: a qualitative extension of a feasibility study

“…Six of 11 participants per group were selected face-toface for the interviews in a joint decision by authors FW and JN, reflecting the greatest possible diversity in terms of gender, age and Expanded Disability Status Scale (EDSS), relying on a purposive sampling strategy, similar to previous studies. 23 24 The number of cases was based on reported sample sizes for qualitative research in feasibility studies. 19 None of the approached pwMS refused to participate in the interviews.…”
