It's hard to fault a study that is essentially a release of raw data collected with minimal analysis. It appears transparent with its methods as well as its biggest limitation (self-selected participants). Still I wonder if the survey they administered is really measuring smartphone addiction vs social media addiction and smartphones happen to be the most convenient delivery mechanism. This makes the participant selection limitation a bigger issue because the paper says participants learned of the study through social media among other methods.
