Effect Of A Theory-Based Multicomponent Ehealth Intervention On Weight Self - Stigma, Bodyweight And Quality Of Life Among Overweight And Obese Adults: A Pilot Randomized Controlled Trial
This study is a two-arm pilot randomized controlled trial designed to evaluate the feasibility and preliminary effects of an Acceptance and Commitment Therapy (ACT) theory-based mobile application integrated with a smartphone pedometer plus health education on weight self-stigma and lifestyle behaviors among overweight or obese adults.
A total of 60 participants will be recruited and randomized 1:1 to the intervention (ACT-based app + pedometer + health education) or control condition. Outcomes will be assessed at baseline (T0), immediately after intervention (T1), and at 1 month after intervention (T2) and 3 months after intervention (T3) following intervention initiation. The primary outcomes are body weight (weight loss) and weight self-stigma measured; secondary outcomes include eating behavior, physical activity level, and quality of life.
Analyses will include per-protocol evaluation using linear mixed-effects models to test group, time, and group-by-time effects on primary and secondary outcomes, with intention-to-treat analyses conducted as sensitivity analyses using multiple imputation for missing weight and weight self-stigma data.
Findings will inform the design of a future definitive trial and contribute evidence on eHealth approaches to reducing weight-related stigma and supporting healthier lifestyles.

Descripción detallada
Participants will be recruited through flyers, physician referrals, and advertisements in local media outlets and on Facebook.
Participants will be screened for eligibility via telephone interviews and in-person conducted by trained researchers, using predefined inclusion and exclusion criteria.
Participants will be randomized to participate in the Mapp-WSSP intervention group or a waitlist.
The MappWSSP intervention group will receive the "mobile app- weight self-stigma program" consisting of 1) a mobile app lifestyle and weight self-stigma intervention 2) a smartphone app to monitor the steps and 3) deliver a total of eight workshops over four weeks, focusing on diet and weight self-stigma reduction practices.
Waitlist control group participants will continue their daily activities until after 3 months, then will be allowed to install the mobile app on their iPhones.
Outcome assessment visits occurred at baseline/randomization, immediately after intervention, 1 month, and 3 months after intervention at the community health center.
at the community health center.
Participants may withdraw from the study at any time without penalty.
To ensure data integrity, all study data will undergo double data entry and verification.

This questionnaire consists of two factors: self-devaluation and fear of enacted stigma, with a total of 12 items.
A Likert 5-point scale was employed, where 1 to 5 represent "strongly disagree" to "strongly agree."
Higher total scores indicate higher levels of weight self-stigma among participants.
