Summary
This study validated a core self-evaluation scale in Korean military members, finding it reliable and correlating with key psychological traits. Results support its use in Eastern cultures and international research.
Area of Science:
- Psychology
- Organizational Behavior
Background:
- Core self-evaluation (CSE) is a key personality construct.
- Validating CSE measures in diverse cultural contexts is crucial for global applicability.
Purpose of the Study:
- To test the psychometric properties of a core self-evaluation scale in Korean military samples.
- To examine the construct validity of the scale by correlating it with established psychological measures.
Main Methods:
- A 12-item core self-evaluation scale was administered to two samples of Korean military personnel (N=181, N=280).
- Factor analysis was used to assess scale structure and internal consistency.
- Correlations were calculated with measures of self-esteem, generalized self-efficacy, neuroticism, locus of control, affect, and job satisfaction.
Main Results:
- Seven items of the scale loaded onto a single factor, demonstrating good internal consistency.
- CSE scores were significantly correlated with all four core traits (self-esteem, generalized self-efficacy, neuroticism, locus of control) as expected.
- Correlations with affect and job satisfaction further supported the scale's validity.
Conclusions:
- The core self-evaluation scale is a valid and reliable measure within an Eastern cultural context (Korean military).
- Findings provide a foundation for future international research on core self-evaluation.
- The study highlights the cross-cultural generalizability of core self-evaluation theory.

01:29Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
03:00Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:30Social Foundations of Self III: Self-Evaluation
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often blend...
01:26Self-Esteem and Culture
Self-esteem, a core psychological construct, is intricately shaped by cultural context and varies significantly between collectivist and individualistic societies. In collectivist cultures such as Japan, self-esteem tends to be flexible, context-sensitive, and influenced by relationships. A Japanese student, for instance, may show restraint in formal settings like school but behave more openly among close friends, reflecting the flexible and dynamic nature of self-concept in such...
01:24Sources of Self-Esteem II: Performance Feedback
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem: self-efficacy,...
