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.

Loneliness in the Norwegian adolescent population: prevalence trends and relations to mental and self-rated health.

Background: Loneliness has become a significant public health problem and should be addressed with more research over a broader period. This study investigates the variations in the prevalence of loneliness among a nationally representative study population of Norwegian adolescents over the last three decades and whether age, gender, self-rated health, and mental distress are associated with these changes.

Methods: Adolescents aged 13-19 years completed the structured and validated questionnaires from the three waves of the Young-HUNT Study: 1995-1997, 2006-2008, and 2017-2019.

The Role of Stress Experience and Demographic Factors for Satisfaction with Life in Norwegian Adolescents: Cross-Sectional Trends over a Ten-Year Period.

Background: The individual's perception of life satisfaction (LS) is regarded as a key indicator of one's overall experience of wellbeing, sensitive to the broad spectrum of functioning. Adolescence is particularly an important period for assessing LS and factors associating with LS. The present study investigated cross-sectional trends in adolescents' LS levels across three time points over a 10-year period, as well as the role of stress experience and socio-demographic differences in association with LS.
