Trial Parameters
Brief Summary
The Physical Activity Self-efficacy (PAS) intervention is a web-based behavioral intervention newly developed to promote physical activity in adults with obesity. The conceptual framework for the PAS intervention is based on self-efficacy theory. The objective of this study is to investigate the feasibility and acceptability of implementing the PAS online intervention for adults with obesity recruited from a local weight management center in the United States of America (USA). The study design is a prospective, double-blind, parallel group randomized pilot trial. Thirty participants will be randomly assigned to the PAS group or usual care group to achieve a 1:1 group assignment. Recruitment of participants is scheduled to begin in January 2024 or earlier at a local weight management center within a private healthcare system in the USA. There are five eligibility criteria for participation in this study (e.g., a body mass index ≥ 25.00 kg/m2). Eligibility verification and data collection will be conducted online. Three waves of data collection will take up to 14 weeks depending on participants' progress in the study. Instruments designed to measure demographic information, anthropometric characteristics, self-efficacy, and acceptability will be included in the survey battery. A research-grade accelerometer will be used to measure free-living physical activity objectively. Data will be analyzed using descriptive statistics and inferential statistical models under an intention-to-treat approach. This study will be sponsored by the Transdisciplinary Areas of Excellence Seed Grant Program from Binghamton University.
Eligibility Criteria
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 b
