Self–Other Agreement on Ratings of Personality Disorder Symptoms and Traits

The present chapter considers the factors important to self–other agreement on personality disorder, reviews the literature on this topic, and presents three meta-analyses with a total of fifty-three studies of self–other agreement on personality disorder (total N = 11,812). Meta-analyses were completed on (1) overall self–other agreement on personality disorder symptoms and traits, (2) self–other agreement on DSM personality disorders, and (3) self–other agreement on maladaptive personality traits measured dimensionally by the Personality Inventory for DSM-5 (PID-5). Overall median self-other agreement was r = 0.37. Self–other agreement on DSM PDs ranged from r = . 32 (dependent PD) to r = 0.51 (antisocial PD). Median self–other agreement was somewhat higher on the PID-5 maladaptive trait domains (r = 0.45), which is in line with prior estimates of the magnitude of self–other agreement on “normal” FFM trait domains.
