Factors of Engagement and Patient-Reported Outcomes in a Stage IV Breast Cancer Facebook Group.

This study examines the factors of online engagement, and the relationship between online engagement and health expectations in a Stage IV breast cancer Facebook group. Members of the Facebook group completed a survey that assessed tie strength, homophily, and health expectations. A content analysis measured optimal social support, and Facebook analytics measured engagement. The results show optimal social support and tie strength are positively related to engagement. However, only optimal social support explains variance in engagement independent of tie strength and homophily. Additionally, the more engaged members are, the more positive their health expectations. The results emphasize the value of optimal social support and engagement in online support groups for individuals with Stage IV breast cancer.
