Qualitative exploration of the acceptability of a mobile phone and pedometer-based physical activity program in a diverse sample of sedentary women.

OBJECTIVES: The objectives of this paper were to explore the acceptability of components of a mobile phone/pedometer-based physical activity program and to understand motivators and barriers to increase physical activity in a diverse sample of sedentary women. DESIGN AND SAMPLE: Face-to-face semi-structured interviews were conducted following a 3-week pilot mobile phone/pedometer-based physical activity intervention. Forty-one sedentary women participated in the study. MEASURES: Subjects were interviewed using a semi-structured interview guide. A qualitative description method was used to thematically analyze the interviews. Two investigators reviewed the transcripts independently and identified codes based on the main concerns in the interview questions.
RESULTS: Three themes emerged from qualitative data shedding light on the perceived acceptability and usefulness of a mobile phone/pedometer-based intervention: (1) Monitor me: mobile phone/pedometer as self-monitoring tools, (2) Motivate me: cycle of feedback in goal setting and usefulness/uselessness of daily random messages, (3) Mobilize me: engaging and adapting physical activity to fit one's own lifestyle.
CONCLUSION: Mobile phone and pedometer-based physical activity programs might be helpful in keeping sedentary women engaged and motivated to increase their physical activity. A randomized controlled trial of this intervention is warranted.
