Oshima, N., Nishida, A., Shimodera, S, et al. (2012). The suicidal feelings, self-injury, and mobile phone use after lights out in adolescents. Journal of Pediatric Psychology, 37(9): 1023-1030.
Associations of mobile phone use after lights out with mental health, suicidal feelings, and self-injury were cross-sectionally examined in 17,920 adolescents. A series of logistic regression analyses were separately conducted for early (grades 7–9) and late (grades 10–12) adolescents. Results suggest that mobile phone use after lights out may be associated with poor mental health, suicidal feelings, and self-injury in both early and late adolescents. The association between reduced sleep and the mobile phone use appears to be confined to early adolescents.
