Aim: To assess the association between problematic smartphone usage and anxiety and depression in adolescents. Methods: A cross‐sectional study in five schools in the UK were included. The primary outcome was moderate anxiety (GAD‐7 ≥10) symptoms and secondary outcomes were moderate depression symptoms (PHQ‐9 ≥10) and insomnia. Problematic smartphone usage was assessed using screentime and the Smartphone Addiction Scale. A multi‐level logistic regression was fitted and adjusted Odds Ratio (aOR) with 95% confidence intervals (95% CI) reported. A mediation analysis was conducted. Results: Of the five included schools, 657 adolescents aged 16–18 years were enrolled. The median age was 17.5 years (17–18 [IQR]) and 508 (77.3%) were female. Of these 188 (28.6%) exhibited moderate anxiety and 226 (34.4%) moderate depression symptoms. Almost two thirds (421, 64.1%) have tried to cut down their smartphone use and 81 (12.5%) wanted help to reduce use. Problematic smartphone use was associated with increased anxiety (aOR = 2.03, 95% CI 1.28–3.23); depression (aOR = 2.96, 95% CI 1.80–4.86); and insomnia (aOR = 1.64, 95% CI 1.08–2.50). Screentime was not associated with anxiety (β = 0.99, 95% CI 0.91–1.08); or depression (β = 0.98, 95% CI 0.89–1.07). Problematic smartphone use had a significant direct, indirect and total effect on both anxiety and depression. Conclusion: Problematic smartphone usage was associated with anxiety and depression, independent of screentime. Interventions are needed to reduce problematic use. [ABSTRACT FROM AUTHOR]
