The Smart City Active Mobile Phone Intervention (SCAMPI)

Study Overview
=================
Brief Summary
-----------------
Physical inactivity is still a major public health problem. Active transportation i.e. walking or cycling for transport can contribute to greater total physical activity. The specific aim of this study is to evaluate if a 12-week mobile phone application can increase time spent in active transportation (cycling or walking) and in moderate-to-vigorous physical activity in Swedish adults aged 20-65 years.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Mobile phone based intervention<br>Participants in the intervention group will receive a 12 week mobile phone based program via a mobile phone application specifically designed for this study. The program will include information, advice and strategies to increase active transportation. Feedback will be provided on personal goals. | Behavioral: Mobile phone based intervention<br>* Participants will receive supporting messages through a mobile phone based intervention.<br>|
