Construction of residents' healthy lifestyle cognitive index system in the context of carbon peaking and carbon neutrality

BackgroundHealthy lifestyle is one of the important factors affecting individual health. How to promote residents' cognition of healthy lifestyle has become an urgent practical problem for the whole society. However, there is no residents' healthy lifestyle cognitive indexes available with consideration of carbon peaking and carbon neutrality. ObjectiveTo construct a cognitive index system for providing effective assessment on residents' cognition of healthy lifestyle under the background of carbon peaking and carbon neutrality. MethodsBased on the health belief model, a preliminary cognitive index system of residents' healthy lifestyle under the background of carbon peaking and carbon neutrality was proposed after literature study and relevant policy review. Then three rounds of indicator importance evaluation and screening by Delphi method were conducted before the index system was finally constructed. The weights of all levels of indicators were determined using analytic hierarchy process. In addition, a self-assessment questionnaire was developed based on the index system. The questionnaire was utilized to conduct a survey among 200 residents by convenience sampling in Shenyang, Liaoning Province from November to December 2021. The survey was used to examine the reliability and validity of the indicator system. ResultsThe effective recovery rates of the three rounds of Delphi method were all 100%. The authority coefficient was 0.84. The Kendall's W consistency test showed good expert consistency (P
