Measuring the relationship between Internet use and well-being poses several methodological chal-lenges that can lead to misleading results, including treating all activities as interchangeable, relying on inaccurate self-reports, and using cross-sectional data, thereby confounding dispositions for using tech-nology with its effects (see Kraut & Burke, 2015 for methodological critiques). The approach used here mitigates some of these problems. We use a panel design to link granular and objective measures of SNS use collected from Facebook’s servers with month-to-month changes in participants’ self-reports of psychological well-being.
