Abstract

IMPORTANCE: Increases in screen time have been found to be associated with increases in depressive symptoms. However, longitudinal studies are lacking. OBJECTIVE: To repeatedly measure the association between screen time and depression to test 3 explanatory hypotheses: displacement, upward social comparison, and reinforcing spirals. DESIGN, SETTING, AND PARTICIPANTS: This secondary analysis used data from a randomized clinical trial assessing the 4-year efficacy of a personality-targeted drug and alcohol prevention intervention. This study assessed screen time and depression throughout 4 years, using an annual survey in a sample of adolescents who entered the seventh grade in 31 schools in the Greater Montreal area. Data were collected from September 2012 to September 2018. Analysis began and ended in December 2018. MAIN OUTCOMES AND MEASURES: Independent variables were social media, television, video gaming, and computer use. Symptoms of depression was the outcome, measured using the Brief Symptoms Inventory. Exercise and self-esteem were assessed to test displacement and upward social comparison hypothesis. RESULTS: A total of 3826 adolescents (1798 girls [47%]; mean [SD] age, 12.7 [0.5] years) were included. In general, depression symptoms increased yearly (year 1 mean [SD], 4.29 [5.10] points; year 4 mean [SD], 5.45 [5.93] points). Multilevel models, which included random intercepts at the school and individual level estimated between-person and within-person associations between screen time and depression. Significant between-person associations showed that for every increased hour spent using social media, adolescents showed a 0.64-unit increase in depressive symptoms (95% CI, 0.32-0.51). Similar between-level associations were reported for computer use (0.69; 95% CI, 0.47-0.91). Significant within-person associations revealed that a further 1-hour increase in social media use in a given year was associated with a further 0.41-unit increase in depressive symptoms in that same year. A similar within-person association was found for television (0.18; 95% CI, 0.09-0.27). Significant between-person and within-person associations between screen time and exercise and self-esteem supported upward social comparison and not displacement hypothesis. Furthermore, a significant interaction between the between-person and within-person associations concerning social media and self-esteem supported reinforcing spirals hypothesis. CONCLUSIONS AND RELEVANCE: Time-varying associations between social media, television, and depression were found, which appeared to be more explained by upward social comparison and reinforcing spirals hypotheses than by the displacement hypothesis. Both screen time modes should be taken into account when developing preventive measures and when advising parents.

  • So far, only a few studies have applied the RI-CLPM method and found only minimal within-person associations between social media use and mental health, primarily measured as depressive symptoms.

    “So far, only a few studies have applied this method and found only minimal within-person associations between social media use and mental health, primarily measured as depressive symptoms [7,20,21].”

    From Social Media and Mental Health Among Early Adolescents in Sweden: A Longitudinal Study With 2-Year Follow-Up (KUPOL Study). (2021) · cites this paper as [7]

    The Results report a within-person association between increased social media use and depressive symptoms. But the Measures section describes a multilevel model with person-mean-centred variables, not an RI-CLPM; the paper also does not characterize the association as minimal. Page numbers were not available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • A systematic review showed a significant relationship between social media use and depression.

    “For example, a systematic review showed that there was a significant relationship between social media use and depression (5).”

    From Relationship of screen time with anxiety, depression, and sleep quality among adolescents: a cross-sectional study (2024) · cites this paper as [5]

    The Key Points identify this paper as a cohort study of 3,826 adolescents, not a systematic review. The Results report a significant association between increased social media use and depressive symptoms, so the finding is supported but the description of the study is not. (LLM, conf=0.93)

    Experimental — accuracy not yet measured
  • Boers and colleagues found a small within-person association between social media use and increased depressive symptoms.

    “Boers and colleagues12 found a small within-person association between social media use and increased depressive symptoms.”
  • Previous within-person studies of social media use and adolescent well-being have reported mixed results.

    “To our knowledge, four recent studies have investigated within-person associations of social media use with different indicators of adolescent well-being (i.e., life satisfaction, depression), again with mixed results6, 11–13.”
  • There is a lack of studies that focus on well-being as a momentary affective state.

    “In addition, while earlier within-person studies have focused on associations with trait-like conceptualizations of well-being11–13, that is, adolescents’ average well-being across specific time periods18, there is a lack of studies that focus on well-being as a momentary affective state.”

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.
