Relationships among three general approaches to personality description

Area of Science:

• Psychology
• Personality Science
• Psychometrics

Background:

• Personality description relies on various theoretical models.
• Key models include Wiggins' Circumplex, Goldberg's Big-Five, and Mehrabian's PAD Temperament.
• Understanding the relationships between these models is crucial for consistent personality research.

Purpose of the Study:

• To investigate the interrelationships among Wiggins' Circumplex, Goldberg's Big-Five, and Mehrabian's PAD Temperament models.
• To determine if core factors of pleasantness, dominance, and arousability can parsimoniously describe personality variance across these models.

Main Methods:

• Reliability analyses were conducted on scales from Wiggins' and Mehrabian's models.
• Interscale correlations were calculated for Goldberg's Big-Five scales.
• Regression and factor analyses were employed to examine the relationships between the models.

Main Results:

• Wiggins' Nurturance and Dominance scales, and Mehrabian's Trait Pleasure, Trait Arousability, and Trait Dominance scales demonstrated high reliability and near independence.
• Goldberg's Big-Five scales showed lower reliabilities with moderate interscale correlations.
• Factor analysis revealed that pleasantness, dominance, and arousability factors adequately explained the variance in all investigated scales.

Conclusions:

• The three basic factors—pleasantness, dominance, and arousability—provide a parsimonious and sufficient description of personality variance.
• These core factors integrate findings across Wiggins' Circumplex, Goldberg's Big-Five, and Mehrabian's PAD Temperament models.
• The study supports a three-factor structure for personality description, offering a unified framework for personality research.
