Rosenberg Self-Esteem Scale Psychometric Analysis for Swedish Adolescents

403 adolescents aged 9-19 from six Swedish schools completed the Rosenberg Self-Esteem Scale (RSES). The dataset includes Rasch model analysis results, showing high person reliability (0.85) and item reliability (0.99), with Cronbach's alpha of 0.87. It evaluates item fit, differential item functioning across sex, age, and BMI, and person-item targeting.

Use Cases

• Analyze differential item functioning (DIF) across sex, age, and BMI categories to assess measurement bias in the RSES.
• Model person-item targeting using participant ability and item difficulty estimates to identify coverage gaps at extreme self-esteem levels.
• Evaluate the psychometric properties of reverse-worded items within the RSES based on Rasch model fit statistics.
• Calculate reliability metrics, including person reliability coefficient (0.85) and Cronbach's alpha (0.87), to validate the scale's internal consistency.

Strengths

• Analysis based on responses from 403 adolescents, providing a substantive sample for psychometric evaluation.
• Reports high reliability metrics, including a person reliability coefficient of 0.85 and Cronbach's alpha of 0.87.
• Includes detailed Rasch model outputs such as item fit statistics and differential item functioning (DIF) analysis across three variables.

Limitations

• The 78.1 KB PDF file contains analysis results, not the raw response data, limiting direct computational use.
• Sample of 403 adolescents from six schools may not be fully representative of broader populations.
• Study notes suboptimal targeting for measuring individuals at very low or very high self-esteem levels.
