In this study, we analyzed characteristics of posts (length of the main text, time of day, existence of exclamation points or question marks in the title) to see if there was a relationship between the number of community comments (as a measure of engagement) and varying levels of the characteristics. The number of comments was used as a measure of engagement because it is an estimate of the extent to which community members were drawn to and felt compelled to interact with the post.

Differences in Engagement Among BabyCenter.com Community Forum Contributors: A Pilot Study
For many women, online health communities, such as BabyCenter.com, provide mediums to quell doubts and receive answers amidst the pressing uncertainties of pregnancy [1]. Women contributing to such community forums often suffer from complications such as postpartum depression, and likely want their posts addressed in a timely and adequate manner. This work examined quantitative and qualitative factors that contribute to various levels of responsiveness to posts in BabyCenter.com post-partum depression online health communities. Our aim was to identify post characteristics conducive to higher levels of engagement from online health forum contributors.
