Trait vs. Disorder
A trait is a psychological quality everyone has to some degree — everyone has some level of self-confidence, anxiety, or sensitivity to rejection, just in different amounts. A disorder, by contrast, is a formal clinical classification that requires precise diagnostic criteria (severity, duration, and functional impact) that only a licensed professional can determine through direct assessment.
This is exactly the distinction our platform applies in the Narcissism Spectrum test, described in our methodology as "the research distinction between grandiose and vulnerable narcissism as traits on a spectrum, not a disorder." The same principle applies to the BPD Awareness test.
In practice, this means your result on these tests tells you where you fall on a trait spectrum compared to others — not whether you "have a disorder." That determination is reserved for a licensed mental health professional.
