Borderline Personality Test

Borderline personality is a condition characterized by difficulties in regulating emotion. People who have borderline elements feel emotions intensely and have a hard time returning to a stable sense of self after an emotionally triggering event. While not everyone who has borderline symptoms suffers from Borderline Personality Disorder, the lifetime prevalence rate of BPD is about 6% of the adult population.

Based on diagnostic criteria from the DSM-5 and the diagnostic screening tool developed by Dr. Zanarini and colleagues, this test assesses the degree to which you demonstrate borderline symptoms.

Do you have borderline traits? For each of the following items, indicate your level of agreement below.
