Concerned About Someone?
If you are worried about a partner, family member, or friend, this questionnaire can help you reflect on whether the behaviours you're observing may be associated with Borderline Personality Disorder (BPD). Each question is framed from your perspective as someone who knows this person.

Important: This questionnaire is a screening tool only. It is not a diagnostic instrument and cannot replace a clinical assessment by a qualified mental health professional. A high score does not confirm that the person has BPD; only a clinician can make that determination. Your answers reflect your observations, which may be incomplete or influenced by your own perspective.
