Rosenberg Self-Esteem Scale Psychometric Analysis for Swedish Adolescents

403 adolescents aged 9–19 years from six Swedish schools completed the Rosenberg Self-Esteem Scale. The dataset supports a Rasch model analysis evaluating item fit, reliability, and differential item functioning across sex, age, and BMI. Key metrics include a person reliability coefficient of 0.85, Cronbach's alpha of 0.87, and a standard error of measurement of 2.11.

Use Cases

• Apply Rasch modeling to assess item fit and person-item targeting for the 10-item RSES.
• Analyze differential item functioning (DIF) across sex, age, and BMI variables to test for measurement bias.
• Evaluate scale reliability using provided coefficients like person reliability (0.85) and Cronbach's alpha (0.87).
• Study the targeting of participant abilities against item difficulties across the self-esteem continuum.

Strengths

• Dataset includes 403 adolescent participants, providing a substantive sample for psychometric analysis.
• Analysis reports strong reliability metrics, including a person reliability coefficient of 0.85 and Cronbach's alpha of 0.87.
• Comprehensive evaluation covers multiple psychometric properties: item fit, DIF, targeting, and response category functioning.
• Data has no significant DIF detected across key demographic variables (sex, age, BMI), supporting measurement invariance.

Limitations

• The 146.4 KB file size indicates the primary data is likely summary statistics within a PDF, not the raw response-level dataset.
• Sample of 403 adolescents from six schools may limit generalizability to other populations or geographic regions.
• Analysis identifies suboptimal targeting and misfit for reverse-worded items, limiting precision at extreme self-esteem levels.
