A small research report found that the primary caregiver for a new born was happier if they socialized and expressed some thoughts on a blog. “Brandon T. McDaniel, who is now a Ph.D. candidate at Penn State, collected data from 157 new mothers, all with Internet access at home. He asked them to complete standard assessments of their feelings of connectedness, their levels of parenting stress and marital conflict and their symptoms of maternal depression. His data showed a positive correlation between blogging and feelings of connectedness to family and friends — which in turn correlates (based on the work of other researchers) with maternal well-being and health. ”
This was the first research of its kind and such results are prompting futher research. One difference between the mothers surveyed and the typical blogger was the reason for blogging. Mothers were overwhelming doing it to stay in touch with family (87%). Bloggers, on the other hand, use it only 37% for that reason. Also, there was some indication that specifically blogging, as opposed to passive social media involvement, is the cause of happiness.
