Validation of Rosenberg self-esteem scale among Norwegian adolescents - psychometric properties across samples.

Background: Self-esteem refers to the evaluative and affective dimensions of the self-concept and is important for positive mental health and overall functioning during adolescence. The Rosenberg Self-esteem scale (RSES) is one of the most frequently used and widely accepted instruments assessing self-esteem; however, the psychometric properties of the instrument have not been investigated in a Norwegian adolescent population. The present study's aim is to investigate the factor structure, construct validity and reliability of the RSES among adolescents 14-21 years.

Bullying, social support and adolescents' mental health: Results from a follow-up study.

The aim of this study was to examine the predictive roles of being bullied and perceived social support in association with adolescents' mental health. At two time points, September 2016 and April-June 2017, questionnaires were distributed to students between 15 and 21 years of age in four upper-secondary schools in Norway, with a total sample size of 351. Random- and fixed-effects regression models were used to estimate the effects of being bullied and social support on adolescents' mental health.
