The widespread use of digital technologies by young people has spurred speculation that their regular use negatively impacts psychological well-being. Current empirical evidence supporting this idea is largely based on secondary analyses of large-scale social datasets. Though these datasets provide a valuable resource for highly powered investigations, their many variables and observations are often explored with an analytical flexibility that marks small effects as statistically significant, thereby leading to potential false positives and conflicting results. Here we address these methodological challenges by applying specification curve analysis (SCA) across three large-scale social datasets (total n = 355,358) to rigorously examine correlational evidence for the effects of digital technology on adolescents. The association we find between digital technology use and adolescent well-being is negative but small, explaining at most 0.4% of the variation in well-being. Taking the broader context of the data into account suggests that these effects are too small to warrant policy change.

The MTF questionnaire contains different questionnaire types that are completed by different subsets of participants. Different numbers of participants, therefore, completed different combinations of questions, the details of which are displayed in this table. DS, depressive symptoms, SE, self-esteem; LO, loneliness.
In both the MTF and YRBS datasets questions were added and changed over the course of the study. This table outlines these alterations, showing both when questions were added and when they were modified.
