Factors Influencing People's Personal Information Disclosure Behaviors in Online Health Communities: A Pilot Study.

To effectively facilitate health information sharing and personal information protection in online health communities (OHCs), it is important to examine the factors influencing people's personal information disclosure behavior in OHCs. Five factors were supposed as the predictors of people's personal information disclosure behavior in OHCs. A total of 376 participants in a Chinese online cancer community were analyzed. The empirical results indicate that more participants give more attention to risk factors than motivating factors when they disclose information in OHCs. In a not so severe condition, participants post their personal information to only obtain needed information. In severe disease situations, participants disclose personal information to obtain both needed information and emotional support, and emotional support is prioritized; in addition, they even risk financial loss to seek more useful information or emotional support. OHC managers should make policies to protect people's personal information, and thus encourage them to share more health information in OHCs.
