Qualitative Exploration of the Acceptability of a Mobile Phone and Pedometer-Based Physical Activity Program in a Diverse Sample of Sedentary Women

Abstract

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. © 2012 Wiley Periodicals, Inc.
