Abstract
During the COVID-19 pandemic lockdown, adolescents relied on social technology for social connection. Although some research suggests small, negative effects for quantity of social technology use on adolescent mental health, the quality of the interaction may be more important. We conducted a daily diary study in a risk-enriched sample of girls under COVID-19 lockdown to investigate associations between daily social technology use, peer closeness, and emotional health. For 10 days, 93 girls (ages 12-17) completed an online daily diary (88% compliance) assessing positive affect, symptoms of anxiety and depression, peer closeness, and daily time texting, video-chatting and using social media. Multilevel fixed effects models with Bayesian estimation were conducted. At the within-person level, more daily time texting or video-chatting with peers was associated with feeling closer to peers that day, which was associated with more positive affect and fewer depressive and anxiety symptoms that day. At the between-person level, more time video-chatting with peers across the 10 days was indirectly associated with higher average positive affect during lockdown and less depression seven-months later, via higher mean closeness with peers. Social media use was not associated with emotional health at the within- or between-person levels. Messaging and video-chatting technologies are important tools for maintaining peer connectedness during social isolation, with beneficial effects on emotional health.
