Guided by the masspersonal communication model, this study examined the impact of the communication channel (masspersonal vs. interpersonal) and support message type on evaluation of social support message quality in Facebook settings. An online factorial experiment with 480 participants revealed that support messages sent through interpersonal channels (e.g., private messaging) were perceived as higher in quality than those sent through masspersonal channels (e.g., status update). Regardless of channels, participants considered tangible support messages as higher quality than informational and emotional support messages. Implications for computer-mediated communication and social support theories and practices were discussed.

在群众交流模型的指导下，本研究考察了交流渠道（男性与人际关系）和支持信息类型对Facebook设置中的社会支持信息质量的影响。一个有480名参与者的在线析因实验显示，通过人际渠道发送的支持消息（例如，私人消息）的质量要比通过群众性渠道发送的支持消息（例如，状态更新）更高。无论采用哪种渠道，参与者都认为有形的支持信息比信息和情感支持信息的质量更高。讨论了对计算机介导的交流和社会支持理论与实践的影响。
