The relationship between five-factor personality measurements and ICD-10 personality disorder dimensions: results from a sample of 229 subjects.
This article examines the relationship between the five-factor model (FFM) and dimensional ICD-10 personality disorders. In a follow-up study of a child and adolescent psychiatric cohort, former patients and controls were assessed with NEO-FFI and the IPDE interview (CD-10 personality disorder). Full data were available for 229 subjects (149 former patients, 80 controls). Multiple regression analysis showed that the five factors of the FFM as independent variables explained between 5% (schizoid personality disorder) and 32% (anxious personality disorder) of the variance of ICD-10 dimensional personality disorder scores. For the two types of emotionally unstable personality disorder dimension (impulsive and borderline), for anxious (avoidant) personality disorder dimension and for the total score of any personality disorder dimension, FFM explained between 17% and 32% of the variance with almost identical results for the former patient group and the control group. High neuroticism was a feature of paranoid, emotionally unstable, histrionic, anankastic, anxious (avoidant), and dependent personality disorder dimensions, whereas low agreeableness was found in dissocial, emotionally unstable and histrionic personality disorder dimensions. Low extraversion was found in schizoid, anxious (avoidant) and dependent personality disorder dimensions, whereas histrionic PD dimension correlated with high extraversion. We find that the FFM is valuable for the further understanding not only of DSM-IV but also of ICD-10 personality disorder dimensions. The differences between ICD-10 and DSM-IV in this respect seem to be small.
