Method
To analyze the relationship between communication on SNSs and well-being, we conducted an opt-in, three-wave panel survey of Facebook users from June to August 2011. Respondents completed validated scales measuring aspects of well-being and questions about their relationships with a set of eight Facebook friends. Survey responses were matched to the server logs of the participants’ activity on Facebook beginning one month prior to the first survey and concluding on the date of the last survey. All data were de-identified and aggregated.
