majority (64%) of studies also found other factors that had a significant negative association with
depression (i.e. body esteem, life satisfaction, self-esteem, positive suicidal idealization, general
belongingness, age, extraversion, agreeableness, conscientiousness, sex, race and perceived
social support) (Choukas-Bradley et al., 2018, Rad & Ahmadi, 2018, Jang et al., 2016, Jasso-
Medrano & Lopez-Rosales, Kircaburn et al., 2018, Kokkinos & Saripanidis, Shensa et al., 2018,
Tang et al., 2017 and Zhang, 2017). The most common was self-esteem, which was measured in
21% of articles (Jang et al., 2016, Kokkinos & Saripanidis, 2017 & Kircaburn et al., 2018). Self-
esteem was measured with zero-order, bivariate or Pearson’s correlations, 14% correlated self-
esteem with depression with -0.41 being the highest correlation and -0.26 the lowest and 7% of
articles correlated self-esteem with mental health (0.44) (Jang et al., 2016) (see table 5). Other
factors measured using various correlation measures included perceived social support,
neuroticism, loneliness, academic stressors, environmental stressors, interpersonal stressors,
satisfaction with life, extraversion, conscientiousness, agreeableness, Facebook network size,
appearance related social media consciousness, body esteem, suicidal ideation, general
belongingness, sex and age (Jang et al., 2016, Kokkinos & Saripanidis, 2017, Zhang, 2017,
Choukas-Bradley et al., 2018, Jasso-Medrano & Lopez-Rosales, 2018 & Kircaburn et al., 2018).
Neuroticism had the highest correlations. When correlated with depression, neuroticism had a
correlation value of 0.58 and when correlated with well-being had a correlation value of -0.68
(Kokkinos & Saripanidis, 2017 & Turel et al., 2018). Loneliness, suicidal ideation and academic
stressors also had relatively high correlations with depression with correlation values 0.52, 0.48
and 0.42, respectively (Kokkinos & Saripanidis, 2017, Jasso-Medrano & Lopez-Rosales, 2018 &
Zhang, 2017). Other factors studied which showed significantly negative associations with
