Answer

Although psychological testing reveals and highlights clinical features, it does not increase diagnostic specificity. Most authors agree that patients with BPD demonstrate ordinary reasoning abilities on structured tests (eg, the Wechsler Adult Intelligence Scale [WAIS]). Abnormal processes are noted only on unstructured projective tests (eg, the Rorschach test). Projective testing highlights circumstantial reasoning and illogical and unrelated connections. In addition, responses of patients with BPD are often overwhelmingly negative.
