Rosenberg Self-Esteem Scale Psychometric Analysis for Swedish Adolescents

A Rasch model analysis of the Rosenberg Self-Esteem Scale (RSES) based on survey responses from 403 Swedish adolescents aged 9–19 years. The study evaluates item fit, reliability, and differential item functioning across sex, age, and BMI. Results include a Cronbach's alpha of 0.87 and a person reliability coefficient of 0.85.

Use Cases

• Assess differential item functioning (DIF) across sex, age, and BMI variables to evaluate measurement bias in the RSES.
• Analyze item fit statistics and person-item targeting to identify gaps in measuring extreme self-esteem levels.
• Examine reliability metrics like Cronbach's alpha (0.87) and person reliability (0.85) to validate the scale's internal consistency.
• Study response category functioning and item difficulty estimates (ISI = 8.38) to refine the psychometric properties of the scale.

Strengths

• Analysis based on 403 adolescent participants, providing a substantive sample for psychometric evaluation.
• Reports high reliability metrics, including a Cronbach's alpha of 0.87 and a person reliability coefficient of 0.85.
• Includes assessment of differential item functioning across three key demographic variables: sex, age, and BMI.

Limitations

• Dataset scope is limited to 403 adolescents from six schools in Sweden, which may not generalize to other populations.
• The analysis identifies suboptimal targeting for extreme levels of the self-esteem trait, limiting measurement precision at high and low ends.
• Primary data is embedded within a PDF report (146.8 KB), requiring extraction for quantitative reuse.
