基于结构方程模型的患者使用国家集采种植体意愿的影响因素研究
A study of factors influencing patients'willingness to use national collection of implants based on structural equation modeling
摘要
Abstract
Objective To explore factors influencing patients'willingness to choose nationally centralized procurement dental implants,improve their acceptance of such implants,and reduce the economic burden of oral implant treatment.Methods A questionnaire survey was conducted among 696 implant patients treated at a tertiary Class A specialized dental hospital in Yantai City(valid response rate:90.86%).Based on the theory of planned behavior(TPB),a structural equation model(SEM)was constructed with six dimensions:attitude,subjective norm,perceived behavioral control,perceived risk,willingness to use,and actual behavior.The structural equation model(SEM)was used to analyze the pathways through which these factors influenced patients'willingness to use implants under the national centralized procurement program.Results The scale demonstrated good reliability and validity(Cronbach's α=0.774,KMO=0.790,cumulative variance explained=70.52%),and the structural equation model demonstrated good fit(CMIN/DF=3.414,RMSEA=0.059,IFI=0.939,CFI=0.939,TLI=0.925).Path analysis revealed that attitude(direct effect=0.15,P<0.05)and subjective norm(direct effect=0.80,P<0.05)had direct positive effects on willingness to use.Willingness to use(direct effect=0.60,P<0.05)and perceived risk(direct effect=0.17,P<0.05)directly influence actual behavior;perceived behavioral norms had no significant effect on intention to use(P>0.05).Among subjective norm indicators,Tfriend recommendation"showed the highest factor loading(1.88),exerting the strongest impact on patient decision-making.Conclusion To encourage patients'adoption of nationally centralized procurement implant systems,it is essential to ensure product quality,minimize adverse events,enhance clinicians'understanding of different implant systems,strengthen the role of clinician recommendations,and improve publicity and patient education regarding procured implants.关键词
