Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study tested whether young people with high anxiety and depression symptoms benefit more from reducing social media use than those with lower symptoms. Over three weeks, 218 distressed young people either reduced social media to one hour per day or continued normal use. Youth with baseline anxiety above clinical thresholds showed significantly greater improvements in anxiety symptoms when reducing social media, compared to those with lower anxiety. The findings suggest reducing social media may help manage anxiety disorders in young people, though effects on depression were less clear.
Key points
- 75% of participants had elevated depressive symptoms and 46% had elevated anxiety symptoms at baseline
- Participants with high baseline anxiety showed clinically meaningful reductions in anxiety symptoms from the intervention
- Baseline anxiety levels moderated the intervention response, but baseline depression severity did not
- The intervention reduced depressive symptoms overall across the sample
- Results suggest a strong causal relationship between social media use and anxiety symptoms in youth
Limitations
The study does not identify which countries the participants were from, limiting understanding of generalizability across different contexts. The three-week intervention period is relatively short, so longer-term effects of social media reduction on mental health remain unknown.
Abstract
Reducing social media use (SMU) leads to small reductions in anxiety and depressive symptoms. However, most studies have been conducted with healthy populations, which may limit observed effects due to floor effects rather than indicating a weak causal link. Youth with elevated anxiety and depression symptoms may be more vulnerable to social media harms and benefit more from reduction, but experimental evidence remains limited for symptomatic samples. The present study examined whether youth with elevated symptoms of anxiety and depression show greater psychological benefits from reducing SMU compared to those with sub-threshold symptoms. A total of 218 out of 260 participants who were randomized to an intervention (reduce SMU to 1 h/day) or control group (no SMU restriction) for three weeks were analysed. Depressive and anxiety symptoms were assessed using CES-D and GAD-7 scales, respectively. At baseline, 75% and 46% of the sample scored above the clinical thresholds for elevated depressive and anxiety symptoms, respectively. Mixed models indicated that baseline anxiety levels moderated the intervention response. Participants above the clinical threshold exhibited significantly greater and clinically meaningful reductions in anxiety symptoms relative to controls compared to those below the threshold. Baseline depressive symptoms severity did not moderate intervention response. Results underscore the strong causal relationship between SMU and anxiety symptoms and suggest that reducing SMU may represent a potential component in the management of anxiety disorders in youth. The intervention reduced depressive symptoms overall, but findings on baseline symptom severity as a moderator of response were inconclusive and require replication.
