BACKGROUND
Unbalanced distribution of medical resources is becoming a big challenge, particularly in selecting doctors. E-consultation could provide patients with more choices of doctors and break out the constraints of time and space. But the acceptance of e-consultation is still poor and the mechanism of adoption is unclear.
OBJECTIVE
This study aims to identify the factors influencing the public intention to use e-consultation and explore the effect path of factors and behavior intention.
METHODS
The hypotheses of our research model were developed based on technology acceptance model and perceived risk theory. A Web-based survey was conducted by a electric questionnaire collection platform and the 29 items questionnaire with 5-point Likert scales were completed by 934 respondents. Structural equation modeling was used to analyze the data. Item evaluation and reliability, validity, path loading, goodness of fit, and multiple-group analysis were used to check moderation effects.
RESULTS
Standardized factor loadings of items were between 0.551 and 0.873. Composite reliability of 9 constructs ranged from 0.706 to 0.840. Average variance extracted ranged from 0.387 to 0.640. The fitness indices showed that the collected data fitted well with the research model. Perceived usefulness was the strongest positive factor effecting behavior intention (β=0.399, P<.001). Perceived ease of use had a positive effect on behavior intention but it is not statistically significant (β=0.117, P=.066), and had a positive effect on perceived usefulness (β=0.537, P<.001). Perceived risk could be well explained by financial risk (β=0.972, P<.001), privacy risk (β=0.774, P<.001), social risk (β=0.871, P<.001), time risk (β=0.894, P<0.001), and psychological risk (β=0.774, P<.001). Perceived risk had negative effects on perceived usefulness (β=-0.375, P<.001) and behavior intention (β=-0.297, P<.001). Personal innovativeness had a positive influence on perceived ease of use (β=0.241, P<.001) and a slight effect on behavior intention (β=0.124, P=.001). Age(χ2=133.457, P<.001) and usage experience(χ2=82.495, P=.019) had a slight moderation effect on the paths.
CONCLUSIONS
Perceived usefulness and perceived risk have significant effects on public intention to use e-consultation. Therefore, platform and manufacturer must improve the function of e-consultation, which will promote the public intention to use e-consultation fundamentally. In order to control the perceived risk of public, government should play an important role in enforcing management of e-consultation markets and approving corresponding medical insurance policies. Besides, personal innovativeness had an effect on behavior intention. And the paths of factors had some heterogeneity among different characteristic people. Therefore, it is necessary to adjust the strategies to fit more groups better.
