Abstract

We lack knowledge of the temporal stability of major personality dimensions in patients with personality disorders (PDs). The Revised NEO Personality Inventory (NEO-PI-R) is a self-report instrument that operationalizes the Five-Factor Model of personality. This study investigated the relative stability, mean level stability, and individual level stability of the NEO-PI-R scores in patients with PDs (n = 393) and patients with symptom disorders only (n = 131). The NEO-PI-R was administered at admission to short-term day treatment and after an average of 19 months. The results showed a moderate to high degree of stability of NEO-PI-R scale scores with no substantial difference in stability between patients with and without PD. Changes in NEO-PI-R scores were associated with changes in symptom distress. Neuroticism was the least stable domain. The study indicates that the Five-Factor Modelof personality dimensions and traits are fairly stable in patients with PDs. The lower stability of Neuroticism may partly be explained by its inherent state aspects.
