This page is for people reflecting on BPD traits in another adult. It can be useful if you are thinking about a friend, partner, colleague, or family member and want a more structured way to notice patterns. If you want to explore your own experience instead, try our companion BPD Assessment – Myself.
Like our self-assessment pages, this page is for reflection and learning, not diagnosis. For now, the most useful next step is the supporter resources page below.
The BPD supporter assessment is coming soon.
Scoring and interpretation
This supporter questionnaire will help you reflect on whether someone shows a pattern that could be relevant to BPD traits. It is not a diagnostic tool, and observations are best treated as prompts for care, curiosity, and better support rather than conclusions.
Note: These tools are screening instruments, not diagnostic tests.
If this page feels relevant, the most helpful next step is usually to learn more about BPD traits in a respectful, evidence-aware way and to approach the person with care, honesty, and practical support rather than labels.
