In online health communities (OHCs), patients can exchange social support through text-based communication. However, research on how various linguistic characteristics of patients' communication in these communities affect their social support outcomes remains limited. This study performs linguistic profiling on OHC participants based on a large dataset and empirically evaluates how lexical, syntactic, semantic, and pragmatic features affect users' communication and social support outcomes. The results show that lexical richness in health-related vocabulary negatively correlates with receiving informational support. The readability and brevity of written texts have positive relationships with incoming social support. Writing longer sentences positively correlates with receiving informational support but negatively correlates with receiving emotional support. Expressing negative sentiment leads to higher chances of receiving both types of social support. The use of terms related to perception and body parts increases the chances of receiving emotional support. The use of terms related to perception words additionally correlates to higher chances of receiving informational support. To receive social supports, being logical in expressions is also critical. Furthermore, the relationships between shared health language and social support are determined by the word category and social support type.

在在线健康社区 (OHC) 中，患者可以通过基于文本的交流交流社会支持。然而，关于这些社区中患者交流的各种语言特征如何影响其社会支持结果的研究仍然有限。本研究基于大型数据集对 OHC 参与者进行语言分析，并根据经验评估词汇、句法、语义和语用特征如何影响用户的交流和社会支持结果。结果表明，健康相关词汇的词汇丰富度与接受信息支持呈负相关。书面文本的可读性和简洁性与获得的社会支持有积极的关系。写更长的句子与获得信息支持呈正相关，但与获得情感支持呈负相关。表达负面情绪会导致获得这两种社会支持的机会更高。使用与感知和身体部位相关的术语会增加获得情感支持的机会。使用与感知词相关的术语还与更高的获得信息支持的机会相关。要获得社会支持，表达的逻辑性也很关键。此外，共享健康语言与社会支持之间的关系由词类和社会支持类型决定。使用与感知和身体部位相关的术语会增加获得情感支持的机会。使用与感知词相关的术语还与更高的获得信息支持的机会相关。要获得社会支持，表达的逻辑性也很关键。此外，共享健康语言与社会支持之间的关系由词类和社会支持类型决定。使用与感知和身体部位相关的术语会增加获得情感支持的机会。使用与感知词相关的术语还与更高的获得信息支持的机会相关。要获得社会支持，表达的逻辑性也很关键。此外，共享健康语言与社会支持之间的关系由词类和社会支持类型决定。
