Optimization of a mHealth Physical Activity Promotion Intervention With Mindful Awareness for AYAO (OPT2MOVE)

The purpose of the present study is to utilize Multiphase Optimization Strategy (MOST)1 to test four social support and mindfulness components (e-coaching, buddy, general mindfulness training, and MVPA-specific mindfulness training) in a 12-week mHealth moderate to vigorous intensity physical activity (MVPA) intervention in a sample of young adult cancer survivors (YACS), to improve quality of life (QOL) and decrease adverse effects and symptom burden. PRIMARY AIM To identify which components from four mHealth components under consideration for inclusion meaningfully contribute to improvements in MVPA at 12 and 24 weeks SECONDARY AIM To examine how changes in MVPA, as a result of Opt2Move components, may influence additional health behaviors and outcomes including: a) symptom burden (i.e. fatigue, depression, anxiety); b) time spent in other activity intensities (i.e. light, sedentary time); and c) sleep duration and quality THIRD AIM To examine potential mediators (i.e. adherence, psychosocial factors such as post-traumatic growth, self-compassion, self-efficacy, and goal setting) and moderators (cancer type, age, gender) of the four intervention components on MVPA.
