Official title
Factorial Trial to Test Unique and Combined Effects of Guided Thinking Tasks to Optimize a Physical Activity Intervention Among Underactive Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objective of this study is to optimize a novel, audio-recorded physical activity intervention that is scalable. Using principles of the Multiphase Optimization Strategy (MOST) framework, a full factorial study will test the unique and combined effects of different intervention components to identify which combination of components is optimal for increasing physical activity and mechanisms by which the components are or are not effective. This information will inform decisions about an optimal intervention package that is effective, efficient, and minimizes participant burden.
