Effect of Prosocial Behaviors on e-Consultations in a Web-Based Health Care Community: Panel Data Analysis

Background: Patients using web -based health care communities for e -consultation services have the option to choose their service providers from an extensive digital market. To stand out in this crowded field, doctors in web -based health care communities often engage in prosocial behaviors, such as proactive and reactive actions, to attract more users. However, the effect of these behaviors on the volume of e -consultations remains unclear and warrants further exploration. Objective: This study investigates the impact of various prosocial behaviors on doctors' e -consultation volume in web -based health care communities and the moderating effects of doctors' digital and offline reputations. Methods: A panel data set containing information on 2880 doctors over a 22 -month period was obtained from one of the largest web -based health care communities in China. Data analysis was conducted using a 2 -way fixed effects model with robust clustered SEs. A series of robustness checks were also performed, including alternative measurements of independent variables and estimation methods. Results: Results indicated that both types of doctors' prosocial behaviors, namely, proactive and reactive actions, positively impacted their e -consultation volume. In terms of the moderating effects of external reputation, doctors' offline professional titles were found to negatively moderate the relationship between their proactive behaviors and their e -consultation volume. However, these titles did not significantly affect the relationship between doctors' reactive behaviors and their e -consultation volume ( P =.45). Additionally, doctors' digital recommendations from patients negatively moderated both the relationship between doctors' proactive behaviors and e -consultation volume and the relationship between doctors' reactive behaviors and e -consultation volume. Conclusions: Drawing upon functional motives theory and social exchange theory, this study categorizes doctors' prosocial behaviors into proactive and reactive actions. It provides empirical evidence that prosocial behaviors can lead to an increase in e -consultation volume. This study also illuminates the moderating roles doctors' digital and offline reputations play in the relationships between prosocial behaviors and e -consultation volume.
