Validation of the MMPI-2 Low Self-Esteem Content Scale

Area of Science:

• Psychological assessment
• Personality psychology
• Clinical psychology

Background:

• Self-esteem is a critical aspect of psychological well-being.
• Accurate measurement of self-esteem is essential for clinical and research purposes.
• The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used psychological assessment tool.

Purpose of the Study:

• To examine the concurrent validity of the MMPI-2 Low Self-Esteem (LSE) Content scale.
• To determine if the LSE scale effectively measures global self-esteem and its specific facets.
• To identify distinct components of low self-esteem using factor analysis.

Main Methods:

• Administered the MMPI-2, Harter Adult Self-Perception Profile, and Rosenberg Self-Esteem Scale to 216 undergraduate students.
• Utilized concurrent validity analysis to compare LSE scale scores with established self-esteem measures.
• Employed factor analysis to identify underlying dimensions of the LSE scale.

Main Results:

• The MMPI-2 LSE scale demonstrated strong concurrent validity as a measure of global self-esteem.
• Factor analysis revealed three distinct subscales within the LSE: Ineptitude, Negative Self-Value, and Negative Comparison with Others.
• The LSE scale and its subscales exhibited good internal consistency, as indicated by alpha and Gutman Split Half coefficients.

Conclusions:

• The MMPI-2 LSE Content scale is a valid and reliable instrument for assessing global self-esteem.
• The identified subscales provide a nuanced understanding of the multifaceted nature of low self-esteem.
• The LSE scale offers a valuable tool for researchers and clinicians evaluating self-esteem constructs.
