Feasibility Study of a Web-Based Physical Activity Intervention for Adults with Obesity
This study is testing a new online program called the Physical Activity Self-efficacy (PAS) intervention. This program aims to help adults with obesity become more physically active by addressing common challenges. Researchers want to see if the PAS intervention is practical to use (feasibility) and if people find it helpful and engaging (acceptability). They will also look for early signs of how well the program works. You may be able to join if you are an adult between 18 and 64 years old. The study plans to enroll 30 participants. The current recruitment status is unclear.
- Study design
- This is a pilot study with 30 participants. It is a randomized, double-blind trial, meaning participants will be randomly assigned to either the PAS intervention group or a usual care group, and neither you nor the researchers will know which group you are in.
- What's involved
- Not specified in the trial record.
- Compensation
- Not stated in the trial record.
- Follow-up
- The study will assess feasibility and acceptability by Week 7, and preliminary effects by Week 14.

What this trial measures
- the feasibility of implementing the PAS intervention (e.g., recruitment rate, eligibility rate) for adults with obesity recruited from a local weight management center in the USA.By Week 7
The feasibility of implementing the PAS online intervention for adults with obesity recruited from a local weight management center in the USA will be assessed with descriptive statistics. Descriptive statistics will include (a) recruitment rate, (b) eligibility rate, (c) consent rate, (d) participation rates, and (e) retention rates.
- the acceptability of implementing the PAS intervention (e.g., engagement, accelerometer-based assessment of physical activity) for adults with obesity recruited from a local weight management center in the USA.By Week 7
The acceptability of implementing the PAS online intervention for adults with obesity recruited from a local weight management center in the USA will be assessed with descriptive statistics. Descriptive statistics will include acceptability of the PAS intervention (e.g., engagement behavior, subjective experience) and acceptability of accelerometer-based assessment of physical activity.
- a preliminary effect size estimate for each direct effect depicted in the conceptual model for the PAS online intervention.By Week 14
Within 7 days after the W1 and W3 survey battery, participants will be asked to enter a code into the PAS intervention website in order to start wearing a physical activity monitor for the next consecutive 7 days. They will be instructed to wear a research-grade accelerometer, ActiGraph wGT3X-BT, on their waist. The primary measure of physical activity in this study will be the average minutes per day of Moderate to Vigorous Physical Activity (MVPA) based on both widely accepted recommendations for health-enhancing physical activity. Instruments designed to measure the acceptability of accelerometer-based assessment of physical activity and self-reported physical activity will also be included in the W1 and W3 physical activity monitoring.
