First-order factor structure of the Personality Research Form

Area of Science:

• Psychology
• Personality Assessment
• Psychometrics

Background:

• The Personality Research Form (PRF) is a widely used instrument for assessing personality traits.
• Establishing the underlying factor structure of the PRF is crucial for its valid interpretation and application.
• Previous factor analyses have yielded varying results, necessitating further investigation.

Purpose of the Study:

• To determine the first-order factor structure of the Personality Research Form (PRF).
• To examine the equivalence of the factor structure across different age groups (high school and college).
• To validate the utility of specific PRF scales for measuring personality constructs.

Main Methods:

• Administered Form AA of the Personality Research Form (PRF) to a high school sample (327 boys) and a college sample (215 men and women).
• Conducted principal component analyses on the 20 PRF scales, subdivided into two subsets, for both samples.
• Compared the derived factor structures between the two samples and with previous analyses by Edwards and Abbott.

Main Results:

• Identified nine equivalent factors in both the high school and college samples.
• Found substantial agreement between the current findings and previous analyses.
• The study demonstrated a consistent first-order factor structure for the PRF across samples.

Conclusions:

• The first-order factor structure of the Personality Research Form is robust and equivalent across high school and college populations.
• Twelve scales of the Personality Research Form are recommended for effectively measuring its core personality constructs.
• These findings support the continued use and interpretation of the PRF in personality research and assessment.
