Background:
Factors contributing to weight variation, and specifically the perception of one's own body, are major elements to take into account in the obesity clinical pathway. The aim of the study was to develop and test the content validity of a multidimensional self-administered questionnaire exploring body-relatedness.
Methods:
A review guided the development of the questionnaire. Fifty-two dimensions and 261 items were extracted. A Delphi method was then performed with 23 experts and 7 patients suffering from obesity. In the 4-Round Delphi, the group rated their agreement on the utility and the relevance of dimensions and items, respectively. The consensus was reached when 75% of members were in agreement.
Results:
Consensus was reached for a 38-dimension and 65-item questionnaire covering 11 domains: (1) body image satisfaction, (2) anxiety about the whole or parts of the body, (3) deviation of logical thinking from reality, (4) socio-cultural influence on appearance, (5) behaviour related to body image, (6) perception of interoceptive signals, (7) perception of health related to body relationships, (8) gap between silhouette perception and reality, (9) reaction to hunger, (10) satisfaction with the sensation generated by touch, and (11) social distances.
Conclusions:
The new clinical tool is multidimensional, the items are specific, easy to understand and to interpret in the clinical care pathway. Through this new tool, we hope to raise professionals' awareness of complex body-related disorders.
