Objective To construct a sedentary behavior evaluation system for office workers based on Delphi method, and provide a basis for further study on sedentary behavior and its influencing factors.
Methods An initial valuation framework of sedentary behavior and its influencing factors was constructed by literature review and expert interview. Two rounds of expert consultation, 30 experts involved in round 1 and 25 experts in round 2, were conducted using questionnaires to refine the dimensions and items of the sedentary behavior evaluation system.
Results The positive coefficients of the two rounds of expert consultation were both above 83%. The authority coefficients of experts on sedentary behavior and related influencing factors were 0.784 and 0.776, respectively. In the two rounds of expert consultation, the Kendall concordance coefficients of sedentary behavior and related influencing factors were all above 0.370 (P < 0.05). The experts achieved a consensus on the sedentary behavior evaluation system for office workers, consisting of sedentary behavior and related influencing factors, and including 2 primary indices, 7 secondary indices, and 43 tertiary indices.
Conclusion A comprehensive and reasonable sedentary behavior evaluation system for office workers is constructed based on Delphi method, showing high levels of expert participation, authority, and concordance.
