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

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.

The study was based on two cross-sectional samples (n = 1,233/ n = 1,816) of adolescents from rural and urban areas in Mid-Norway. Concerning the dimensionality of the RSES, two measurement models were tested using Principal Component Analysis and Confirmatory Factor Analysis: a one-factor model and a two-factor-model.

The results show that a two-factor solution of positive and negative aspects of self-esteem representing "perceived personal competence" and "self-value" had the best fit across the two adolescent samples. The RSES also showed high reliability and correlated in expected directions with measures of life satisfaction, stress, and self-efficacy, supporting the convergent validity of the instrument.

The psychometric properties of the RSES need to be further evaluated in Norwegian adolescent populations based on the dimensionality found in the present study; however overall, the results indicate that the instrument is appropriate for assessing self-esteem among Norwegian adolescents.
