Summary
The revised Generalized Expectancy for Success Scale (GESS) demonstrates strong reliability and validity in college students. This validated measure of success expectancies is suitable for psychological research and assessment.
Area of Science:
- Psychological assessment
- Personality psychology
- Educational psychology
Background:
- The Generalized Expectancy for Success Scale (GESS) is a key measure in understanding individual differences in achievement motivation.
- Previous versions of the GESS required revision to enhance its psychometric properties for contemporary research.
Purpose of the Study:
- To revise and validate the Generalized Expectancy for Success Scale (GESS).
- To assess the reliability and validity of the newly revised GESS in a college student population.
Main Methods:
- The revised GESS was administered to 199 college students.
- Correlations were examined with Rosenberg Self-Esteem Scale, Life Orientation Test, and Rotter's Internal-External Locus of Control Scale.
- Further validation included the Eysenck Personality Inventory and a risk-taking task for subsamples.
Main Results:
- Item analysis identified 25 items with strong correlations (≥ .45) to the total score.
- The revised GESS exhibited high internal consistency.
- Excellent test-retest reliability was confirmed for the scale.
Conclusions:
- The revised GESS is a psychometrically sound instrument for measuring generalized expectancies for success.
- The scale's reliability and validity support its use in research on motivation and personality.
- This validated tool aids in understanding factors influencing academic and personal achievement.
