社交反馈在Reddit减肥社区中的作用

The Effect of Social Feedback in a Reddit Weight Loss Community

Tiago O. Cunha, Ingmar Weber, Hamed Haddadi, Gisele L. Pappa

摘要:

人们普遍认为,接受社会反馈有助于(i)保持个人与社区的互动,以及(ii)促进个人积极的行为改变。然而,关于社会反馈对持续参与在线健康社区的影响的定量数据很少。在这项工作中,我们应用Mahalanobis距离匹配(MDM)来证明在Reddit上的“loseit”减肥社区中接收反馈的重要性。具体地说,我们表明,(i)即使在纠正单词选择的差异时,用户在最初的帖子中获得更多积极反馈的可能性更大,并且(ii)有收益递减,后期帖子的社会反馈不如第一个帖子重要。我们还描述了更有可能吸引这种有价值的社会反馈的初始帖子的类型。虽然我们还不能争论最终减肥成功或失败,但我们相信,了解在线健康社区背后的社会动态是设计更有效干预措施的重要一步。

英文摘要:

It is generally accepted as common wisdom that receiving social feedback is helpful to (i) keep an individual engaged with a community and to (ii) facilitate an individual's positive behavior change. However, quantitative data on the effect of social feedback on continued engagement in an online health community is scarce. In this work we apply Mahalanobis Distance Matching (MDM) to demonstrate the importance of receiving feedback in the "loseit" weight loss community on Reddit. Concretely we show that (i) even when correcting for differences in word choice, users receiving more positive feedback on their initial post are more likely to return in the future, and that (ii) there are diminishing returns and social feedback on later posts is less important than for the first post. We also give a description of the type of initial posts that are more likely to attract this valuable social feedback. Though we cannot yet argue about ultimate weight loss success or failure, we believe that understanding the social dynamics underlying online health communities is an important step to devise more effective interventions.
