Physical Activity: Feasibility Study

There are five eligibility criteria for participation in this study. Values for each of the eligibility criteria will be based on self-report by the potential participant. Potential participants who do not meet one or more of the eligibility criteria will be informed that they are ineligible for the study and then will be taken to the exit page from the PAS website (http://pasintervention.com/login). * The first criterion is being between 18 and 64 years old, consistent with evidence-based age groupings for global recommendations on physical activity for health. * The second criterion is a body mass index (BMI) ≥ 25.00 kg/m2, consistent with many physical activity interventions in adults with obesity. A justification for this criterion is the need to promote physical activity in a BMI-based population in which few individuals may meet public health guidelines for physical activity. * The third criterion is the ability to access the online intervention. This criterion will be assessed by asking them to confirm that they will have access to a technological device (e.g., computer, smart phone) that can access the online intervention via a web browser. * The fourth criterion is a willingness to comply with instructions for physical activity monitoring. This criterion will be assessed by asking them if they are willing to wear a physical activity monitor on their waist for two 7-day intervals and complete a daily log sheet regarding wear time during each of the two 7-day intervals in the study. A justification for this criterion is based on previous studies where a similar question was asked to potential participants at screening. Those who indicate a willingness to comply with instructions for physical activity monitoring will be asked to provide information about their non-dominant hand. * The final criterion is a willingness to respond to study-related contacts (e.g., email, text message, phone call). A justification for this criterion is that participants will be asked to complete some tasks in a specifically structured schedule.
