Team Science to Promote Physical Activity

Fun For Wellness is an online intervention designed to promote growth in well-being and physical activity by providing confidence-enhancing learning opportunities to participants \[1\]. The conceptual framework for the Fun For Wellness intervention is guided by self-efficacy theory \[2\]. Evidence has been provided for the efficacy of Fun For Wellness to promote self-reported physical well-being actions in free-living adults who comply with the intervention \[3\]. The objective of this feasibility study is to address uncertainties regarding the inclusion of accelerometer-based assessment of physical activity within the Fun For Wellness online intervention among free-living adults with obesity in the United States of America. Four specific aims will be investigated. Aim 1. To determine if accelerometer-based assessment of physical activity can be used within the Fun For Wellness intervention. Aim 2. To determine if accelerometer-based assessment of physical activity should be used within the Fun For Wellness intervention. Aim 3. To determine how to implement accelerometer-based assessment of physical activity within the Fun For Wellness intervention. Aim 4. To provide a preliminary effect size estimate for each direct effect in the conceptual model for the Fun For Wellness online intervention. Pursuit of these four specific aims is based on a general conceptual framework for feasibility and pilot studies in preparation for a future definitive randomized controlled trial \[4-6\]. Within this conceptual framework, a randomized pilot trial is a type of a feasibility study and a feasibility study may include a focus on the acceptability of an intervention \[4-6\].
