Abstract
The current article reports on the development, psychometric properties, and external validity of an informant-report form of the Personality Inventory for DSM-5 (the PID-5-IRF). Using data from two nationally representative samples, as well as an elevated-risk community sample, we report on the PID-5-IRF item characteristics, scale properties, superordinate factor structure, and correlations with other measures. The PID-5-IRF replicates the factor structure of the self-report form and has relationships with other measures (including the PID-5 self-report form and a widely used Big Five measure) that are consistent with previous research and theory. We believe that the PID-5-IRF is a useful measure for a number of scenarios, such as when additional sources of information are desired, where informant measures are expected to provide incremental validity over self-report, where relationships or social perception is a focal interest, or when response bias is a salient concern. Areas for future research are also discussed.
