Results: Performance expectation (β=.282; P<.001), social influence (β=.238; P=.02), and facilitating conditions (β=.279; P=.002) positively affected users’ willingness to adopt health information, whereas effort expectancy (P=.79) and perceived risk (P=.41) had no significant effects. Gender had a significant moderating effect in the structural equation model (P<.001). Conclusions: SQAC users’ willingness to adopt health information was evidently affected by multiple factors, such as performance expectation, social influence, and facilitating conditions. The structural equation model proposed in this study has a good fitting degree and good explanatory power for users’ willingness to adopt health information. Suggestions were provided for SQAC operators and health management agencies based on our research results. %M 33970865 %R 10.2196/27811 %U //www.mybigtv.com/2021/5/e27811 %U https://doi.org/10.2196/27811 %U http://www.ncbi.nlm.nih.gov/pubmed/33970865
