A Qualitative Study on the Feasibility and Acceptability of Concealed Weighing

Abstract Objectives Modern weight management approaches emphasize sustainable healthy behaviors over mere weight loss. However, regular weigh-ins in these programs can jeopardize weight-neutral goals, leading to biases, unhealthy behaviors, and attrition. This study explores the feasibility and acceptability of concealed weighing, a method that conceals from participants that they are being weighed. Methods Through qualitative interviews, the study aimed to provide preliminary insight into how concealed weighing was perceived by individuals seeking to maintain or lose weight. Results Thematic analysis of 16 interviews identified three key themes: (1) the participants sentiments towards concealed weighing; (2) how concealed weighing differed from typical overt weigh-ins; and (3) how concealed weighing reduced certain validity issues that may have influenced study outcomes. Participants largely accepted the concealed weighing method, reporting a more relaxed, comfortable, and positive engagement with the study. Minimal negative reactions were noted over the nature of the deception. The absence of knowledge about being weighed alleviated stress and anxiety, allowing participants to focus on study objectives without fixating on their weight. Reflections on traditional overt weighing revealed anticipated feelings of shame and judgment, with participants acknowledging that overt weighing would have influenced their behaviors and responses, leading to compensatory actions and potential biases. Conclusion Concealed weighing appears to be feasible and acceptable in weight-related research, reducing discomfort and minimizing behavioral and response biases, thereby improving participant engagement and data validity. However, the ethical implications of deception require thorough investigation. Further research should rigorously assess the advantages and limitations of the concealed weighing method.
