The Ego-Grasping Scale shows moderate reliability but identifies five components, suggesting varied item content. Lower scores correlate with better psychological health, and the scale is useful for cross-cultural research.
Area of Science:
- Psychology
- Psychometrics
Background:
- The Ego-Grasping Scale by Knoblauch and Falconer is a tool for assessing ego-grasping.
- Its psychometric properties and cross-cultural applicability require examination.
Purpose of the Study:
- To review research on the Ego-Grasping Scale.
- To evaluate its reliability, internal structure, and cross-cultural utility.
Main Methods:
- Review of existing research on the Ego-Grasping Scale.
- Analysis of reliability using Cronbach's alpha, odd-even, and test-retest methods.
- Principal-components analysis with varimax rotation was performed on a sample of 695 undergraduate students.
Main Results:
- The scale demonstrated moderate reliability across different measures.
- Principal-components analysis revealed five distinct components, indicating content heterogeneity.
- A negative association was found between Ego-Grasping scores and psychological health.
- The scale has been successfully translated and utilized in Korean, Kuwaiti, and Turkish populations.
Conclusions:
- The Ego-Grasping Scale exhibits moderate psychometric properties.
- The identified components suggest a multidimensional construct.
- Lower scores on the scale are linked to improved psychological well-being.
- The scale's cross-cultural adaptability makes it valuable for international psychological research.
