Development and validation of the good and evil character traits (GECT) scale

Area of Science:

• Psychology
• Moral Psychology
• Personality Assessment

Background:

• Assessing moral character is crucial for understanding human behavior.
• Existing measures may not fully capture the nuances of good and evil traits.
• A comprehensive scale is needed to evaluate positive and negative moral attributes.

Purpose of the Study:

• To develop and validate a reliable and valid scale for measuring good and evil character traits (GECT).
• To identify specific items that effectively differentiate between positive and negative moral descriptors.
• To provide a psychometric instrument for research on morality and personality.

Main Methods:

• A large pool of moral character descriptors (3,614) was sourced from contemporary Chinese language.
• Exploratory Factor Analysis (EFA) and Parallel Analysis (PA) were used to refine the scale items.
• Confirmatory Factor Analysis (CFA) was employed to validate the factor structure with independent samples.

Main Results:

• The initial pool was condensed into a 55-item scale, further refined to 53 items (21 good, 32 evil).
• EFA and PA identified the underlying factor structure.
• CFA confirmed the 53-item GECT scale's factor structure in Study 1.
• Validity was supported by correlations with Honesty-Humility and the Dirty Dozen scale in Study 2.

Conclusions:

• The Good and Evil Character Traits (GECT) scale is a validated psychometric instrument for assessing moral character.
• The scale provides a nuanced measure of both positive and negative moral attributes.
• Findings support the GECT scale's utility for future research in personality and moral psychology.
