“…As a result, the research field has shifted its focus to the effects of social media on mental health in particular. Prior reviews or meta-analyses on either problematic SMU or more descriptive and non-pathological forms of SMU report primarily small, negative relationships between SMU and MH (Appel et al, 2020;Baker & Algorta, 2016;Best et al, 2014;Çikrıkci, 2016;Elhai et al, 2017;Glover & Fritsch, 2018;Huang, 2010Huang, , 2017Keles et al, 2020;Liu et al, 2019;Marino et al, 2018;Richards et al, 2015;Rozgonjuk et al, 2020;Sarmiento et al, 2020;Seabrook et al, 2016;Yoon et al, 2019). Most of those meta-analyses yield small, negative correlation coefficients, but these vary depending on specific concepts and inclusion criteria, ranging from −.33 (Yoon et al, 2019, for SMU upward social comparison andIvie et al, 2020, for depression) to .14 (Liu et al, 2019, for SMU interaction and mental health).…”
