eMOTION Formative Study

Using Real-Time Data Capture to Examine Affective Mechanisms as Mediators of Physical Activity Adherence in Interventions: Formative Study

The eMOTION Study is a two-part ORBIT model phase 1 trial. The first part, called the Formative Study, will assess acceptability and feasibility of a novel physical activity intervention in adults at increased risk for cancer due to overweight or obesity.

The eMOTION Study is a two-part ORBIT model phase 1 trial. The first part of the eMOTION Study, the Formative Study, will iteratively test and refine the implementation of a novel treatment to manipulate affective mechanisms during physical activity among individuals at higher risk for cancer due to overweight or obesity. Acceptability and feasibility of content, delivery, device usage, engagement, and achieving clinically meaningful changes in affective mechanisms will be addressed. Treatment components targeting intensity-based goals and affect-based goals will be tested separately in four groups.

Inclusion Criteria:

• adults aged ≥18 years
• residing in the United States
• self-reported BMI ≥ 25
• currently engaging in < 60 minutes per week of structured physical activity
• owning a personal smartphone device
• residing in an area with Internet or Wi-Fi connectivity during the study period
• able to speak and read in English
• interested and willing to start a physical activity program
• willing to wear a Fitbit Versa smartwatch provided by the study team everyday continuously (including at work and during physical activity), in place of any Fitbits or smartwatches they previously wore, for the duration of the study period
• able to read the small font on a smartwatch screen without glasses, or willing to carry reading glasses during physical activity for the purpose of reading the smartwatch screen

Exclusion Criteria:

• unable to provide informed consent due to cognitive disability
• unable to engage in one or more key treatment components, including those with medical conditions that preclude physical activity engagement or who cannot wear an accelerometer on the wrist for any reason
