“…Consistent with the displacement hypothesis, frequent screen time is associated with cognitive and behavioral delays (Madigan, Browne, Racine, Mori, & Tough, 2019; McNamee, Mendolia, & Yerokhin, 2019), academic difficulties (Adelantado‐Renau et al, 2019; Mundy et al, 2020), lower levels of emotional well‐being and greater anxiety, emotional instability, self‐harm, depression and suicidal ideation (e.g., Barthorpe, Winstone, Mars, & Moran, 2020; Twenge & Campbell, 2019), comorbid internalizing and externalizing problem behaviors (Riehm et al, 2019), lower self‐value (McNamee et al, 2019), increased risk for attention deficit hyperactivity disorder‐related behaviors (George et al, 2018; Ra et al, 2018), and poorer perceived quality of life (Stiglic & Viner, 2019) in analyses adjusted for possible confounds. Negative associations between children’s frequency of being online and their cognitive, academic, behavioral, and physical development are evident after more than 1 hr of daily use (Mundy et al, 2020; Sampasa‐Kanyinga & Chaput, 2016; Sampasa‐Kanyinga, Chaput, & Hamilton, 2019; Twenge & Campbell, 2019). Frequent use of online technologies is also associated with substance use, risky sexual behaviors, problematic gambling, and cyberbullying (e.g., Kaur, Rutherford, Martins, & Keyes, 2020; Vannucci, Simpson, Gagnon, & Mccauley, 2020).…”
