简要总结
The goal of this observational survey pilot study is to learn how 3D visualization tools (i.e., personalized avatars) influence weight loss goals, satisfaction, confidence, and commitment compared to numerical weight outcomes in weight loss-seeking adults.
The main questions it aims to answer are:
- What are contemporary weight loss goals (defined as dream, happy, acceptable, and disappointing weight loss outcomes), and how do they compare to goals reported in prior studies?
- Does presenting weight loss outcomes using personalized 3D avatars result in different levels of satisfaction compared to presenting equivalent outcomes numerically as body weight?
- Do predictive 3D avatars affect participants' confidence and commitment to achieving weight loss differentially than numerical weight loss goals?
Researchers will compare visual (3D avatar-based) weight loss outcomes to numerical (pounds lost) weight loss outcomes to see if visual presentation lowers satisfaction with potential weight loss and alters confidence and commitment.
Participants will:
- Complete a one-time online survey
- Provide demographic and self-reported anthropometric information to generate personalized 3D avatars
- Report weight loss goals and rate satisfaction with potential weight loss outcomes shown numerically and as 3D avatars.
- Complete questionnaires assessing psychological and behavioral weight-related factors.

研究组 & 干预措施
Weight Loss-Seeking Adults
Participants are presented with personalized, predictive 3D digital avatars representing their current body shape and projected changes in body shape across increasing levels of weight loss. Avatars are generated using participants' self-reported demographic and anthropometric information. Weight loss outcomes presented visually via avatars are compared within participants to equivalent outcomes presented numerically as body weight (in pounds) to evaluate differences in weight loss satisfaction, confidence, and commitment.
干预措施: Personalized 3D Body Visualization (Behavioral)
结局指标
主要结局
Weight Loss Goals
时间窗: assessed once during the online survey
Self-reported dream, happy, acceptable, and disappointing weight loss goals, reported as body weight and calculated percent reduction from current body weight.
Weight Loss Satisfaction
时间窗: assessed once during the online survey
Participant-reported satisfaction with hypothetical weight loss outcomes presented across increasing percentages of total body weight loss, shown both visually using personalized 3D avatars and numerically as body weight. Satisfaction is rated on a 10-point scale.
次要结局
- Confidence in Achieving Weight Loss(assessed once during the online survey)
- Commitment to Weight Loss(assessed once during the online survey)
