There is more consistent evidence for an association between screen time and depression.
Other reviews of the literature concluded that there was insufficient or inconclusive evidence for an association between screen time and anxiety. Of the four studies, only one was assessed as having strong methodological quality. The two remaining studies either found no association or an inverse association (in a cross-sectional study and prospective cohort, respectively). However, like many in this field, these studies were cross-sectional and could not assess the temporal direction of association. Of the four studies in the review that explored the association between increased screen time and anxiety, two found positive associations. Teychenne and colleagues recently systematically reviewed the literature on the association between sedentary behaviour and anxiety they included studies that specifically examined screen time. Alongside increases in screen time there has been an increase in the recorded incidence of common mental health disorders in children and adolescents, leading us to question whether they are related.

The report found that screen-based products were commonly used by children and adolescents, with 79% of 12–15 year olds owning their own smart phone, and 48% of 5–15 year olds having a TV in their bedroom in 2016. Patterns of screen use also differ depending on time of the week, with more time spent using screens on weekends than weekdays.
A report in 2017 suggested that British children aged 5–15 years spent 1.5 more hours per week online than watching TV which is in contrast to their findings in 2007 when they spent roughly 5 h more per week watching TV than online. The amount and nature of time spent using screen-based devices such as televisions, computers, and mobile phones has changed over recent years. Time spent alone was found to attenuate some associations, and further research should explore this. We found associations between increased screen time, particularly computer use, and a small increased risk of anxiety and depression. There was little evidence for associations with texting or watching television. Adjusting for time spent alone attenuated effects for anxiety but not depression. Greater time spent using a computer on weekend days only was associated with a small increased risk in depression (OR for 1–2 h = 1.12, 95% CI: 0.93 to 1.35 OR for 3+ hours = 1.35, 95% CI: 1.10 to 1.65, p for linear trend = 0.003).
We found a similar association between computer use at weekends and anxiety (OR for 1–2 h = 1.17, 95% CI: 0.94 to 1.46 OR for 3+ hours = 1.28, 95% CI: 1.03 to 1.48, p for linear trend = 0.03). More time spent using a computer on weekdays was associated with a small increased risk of anxiety (OR for 1–2 h = 1.17, 95% CI: 1.01 to 1.35 OR for 3+ hours = 1.30, 95% CI: 1.10 to 1.55, both compared to < 1 h, p for linear trend = 0.003). Using ordinal logistic regression, we adjusted for multiple confounders, particularly focussing on activities that might have been replaced by screen time (for example exercising or playing outdoors). We assessed associations between various types of screen time (watching television, using a computer, and texting, all measured via questionnaire at 16y), both on weekdays and at weekends, and anxiety and depression (measured via the Revised Clinical Interview Schedule at 18y). Participants ( n = 14,665 complete cases n = 1869) were from the Avon Longitudinal Study of Parents and Children, a UK-based prospective cohort study. We examined associations between screen time measured at 16 years and anxiety and depression at 18. There is limited and conflicting evidence for associations between use of screen-based technology and anxiety and depression in young people.
