Reciprocal Longitudinal Associations Between Adolescents’ Media Consumption and Psychological Health
Abstract
Objective This study investigated reciprocal longitudinal associations between media use/physical activity and adolescents' psychological health.Methods Data were collected between 2011 and 2017 in the LIFE Child study in Germany. The sample included 814 10- to 17-year-old adolescents. The participants provided information on their media use per day (hours of television/video, computer/Internet, and mobile phone use), physical activity (frequency of organized and non-organized physical activity per week), behavioral difficulties (emotional problems, conduct problems, hyperactivity/inattention, peer relationship problems), and quality of life (physical and psychological well-being; satisfaction with parents, peers, and school) at 2 time points 12 months apart. Multiple regressions were applied to analyze reciprocal longitudinal associations between media use/physical activity and behavioral difficulties/quality of life.Results Frequent use of computers/Internet at baseline was associated with an increase in internalizing behavioral difficulties (emotional problems and peer relationship problems) at follow-up. Additionally, a high frequency of computer/Internet and mobile phone use was related to a decrease in psychological well-being, whereas a high frequency of organized physical activity was linked to improved physical well-being. The analyses also revealed a link between more behavioral difficulties at baseline and increased television consumption at follow-up.Conclusion This study suggests mutual dependencies between electronic media use and psychological health over time.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
