報告內容簡介：
Online health communities (OHCs) play an important role in enabling patients to exchange information and obtain social support from each other. However, do OHC interactions always benefit patients? In this research, we investigate different mechanisms by which the sentiment of OHC content may affect patients’ moods. Specifically, we notice users can read not only emotional support intended to help them, but also emotional support targeting other persons or posts unintended to generate any emotional support (named auxiliary content). Drawing from emotional contagion theories, we argue even though emotional support may benefit targeted support seekers, it could have a negative impact on the moods of other patients. Our empirical study on an OHC for depression patients supports these arguments. Our findings are new to the literature and critical to practice since they suggest that we should carefully manage OHC-based interventions for depression patients. In the follow-up analysis, we show the possibilities to alter the intervention volume, length, and frequency to tackle the challenge of the negative effect. In the study, we design a novel deep learning model to differentiate emotional support from auxiliary content. We show this differentiation is critical for identifying the negative effect of emotional support on unintended recipients.
