BPD Test is a free educational website that helps adults reflect on patterns and find reputable information. It is not a clinic, crisis service, diagnostic provider, or substitute for professional care.
Checklist version 2.0.0
The custom checklist contains four prompts in each of five themes: emotional patterns, relationship patterns, sense of self, impulsive reactions, and stress responses. Every prompt uses the same past-three-month timeframe and five-point frequency scale.
The browser averages the four responses within each theme and maps that average to a frequency description. Themes are equally represented. The site does not convert the total into a disease probability or clinical threshold.
An optional direct safety question is separate from scoring, storage, and analytics. Crisis support remains visible regardless of answers because a general checklist cannot assess immediate safety.
Progress and results are stored in localStorage on the user’s device. Advertising and analytics still load site-wide, but checklist answers, theme summaries, and the safety response are not sent as analytics or ad parameters by the application.
Educational pages prioritize primary public-health and clinical-guideline sources, currently including the U.S. National Institute of Mental Health and NICE. Sources are linked beside the claims they support or in a clearly labeled source section.
We avoid unsupported prevalence or outcome percentages, invented testimonials, professional-review claims without named evidence, and language that presents the checklist as clinical. Material pages display a reviewed date and should be rechecked when guidance or crisis resources change.
No named clinician or medical reviewer is claimed because the project does not currently document one. Content corrections can be sent to [email protected].
