Results show that the 16 facets have good psychometric properties and test-retest reliability, are generic across various types of personality disorders, and have good discriminative validity between various populations. The facets fit well into a common factor model with five higher-order domains (i.e., self-control, identity integration, responsibility, relational capacities, and social concordance) that are eminently interpretable, and replicable across various populations. Domain scores are strongly associated with interview ratings of the severity of personality pathology. Taken together, the SIPP-118 provides a set of five reliable, robust and valid indices of personality problems.
