Summary
The Personality Assessment Inventory-Borderline Features Scale (PAI-BOR) 4-factor structure did not fit well in a large nonclinical sample. A 6-factor model demonstrated a superior fit for the PAI-BOR items.
Area of Science:
- Psychological assessment
- Personality disorders
- Psychometrics
Background:
- The Personality Assessment Inventory-Borderline Features Scale (PAI-BOR) is a widely used measure.
- Morey (1991) proposed a 4-factor structure for the PAI-BOR.
- Evaluating the factor structure of psychological measures is crucial for their validity.
Purpose of the Study:
- To assess the fit of Morey's (1991) 4-factor model for the PAI-BOR.
- To identify the optimal factor structure for the PAI-BOR in a nonclinical population.
Main Methods:
- Exploratory and confirmatory factor analyses were conducted.
- The study utilized a large sample of approximately 5,000 nonclinical participants.
- Item covariances of the PAI-BOR were analyzed.
Main Results:
- Morey's (1991) proposed 4-factor structure did not adequately fit the PAI-BOR data.
- A 6-factor model provided a significantly better fit to the item covariances.
- The findings suggest a revised factor structure for the PAI-BOR.
Conclusions:
- The original 4-factor structure of the PAI-BOR may not accurately represent its underlying dimensions in nonclinical samples.
- A 6-factor model offers a more robust representation of the PAI-BOR's structure.
- Further research may be warranted to refine the PAI-BOR's factor structure and interpretation.
