ABSTRACT
Objectives:
The purpose of this study is to analyze structural relationships between the service quality of u-health and the attitude toward u-health between potential demanders and supplier groups of u-health service through cross-validation method.
Methods:
We used a survey data, collected from medical doctors and latent u-health users by Korea Institute for Health and Social Affairs (KIHASA) to confirm and show the demand for u-health in 2011. We analyzed data from 731 medical doctors and 600 potential users of u-health by using SPSS 19.0 and AMOS 20.0 programs. Parameter estimates of the service quality and the attitude toward u-health were cross-validated through multi-group confirmatory factor analysis between u-health suppliers (medical doctors) and latent u-health users.
Results:
We showed that multi-group confirmatory factor analysis was appropriate for both groups, u-health suppliers and users. Service quality of u-Health was a significant factor to attitude toward u-health in both groups.
Conclusions:
Cross-validated measures between suppliers and users for the service quality and the attitude toward u-health should be standardized and useful in future research on u-Health.
Key words: u-health, Cross validation, Service quality, Attitude, Structural equation modeling, SEM
