The DSM-5 Section III model of personality disorders remains largely unexplored
in older adults. More specifically, there is a need for further research
on the generalizability of the five trait domains in old age. The development
of a short operationalization to screen for maladaptive trait domains, the
Personality Inventory for DSM-5 Brief Form (PID-5-BF), can stimulate the
use of the alternative DSM-5 model in older adults by addressing the need
for short instruments. The primary goal of this study was to examine the
construct validity of the PID-5-BF by comparing its structural model and
nomological network with the original PID-5 in terms of relations with
domains of personality functioning and a gero-specific personality disorder
indicator. A five-factor model was supported, but the domain Disinhibition
was not replicated in the original PID-5, and some PID-5-BF items showed
weak loadings. Nevertheless, the nomological network was similar and
showed meaningful relations, supporting the use of the Brief PID-5 in older
clinical samples.
