Association between loneliness, self-esteem and outcome of life satisfaction in Norwegian adolescents aged 15-21.

Adolescence is an important developmental stage for understanding the role of perceived loneliness and self-esteem on life satisfaction. This study investigated the association between loneliness, self-esteem and the outcome of life satisfaction, as well as potential interaction effects in association with life satisfaction, in a sample of Norwegian adolescents. The study was based on a cross-sectional sample of 1816 adolescents aged 15-21 years. Data were collected in September 2016. The participants reported scores on the five-item Satisfaction with Life Scale, the 10-item Rosenberg Self-Esteem Scale and one item assessing loneliness. Control variables included sex, age, perceived family economy, parents' education, place of birth and perceived bullying. The data were analysed with descriptive and multiple linear regression analysis. A significant negative and moderately strong association was found between loneliness and life satisfaction, where the association was stronger for girls than for boys. Self-esteem showed a significant positive and strong association with life satisfaction; however, no significant interaction effect was found.
