Background
Borderline personality patterns show up as ongoing instability — in mood, in relationships, in how someone sees themselves, and in behavior. This instability can get in the way of family life, work, long-term plans, and just having a steady sense of "who I am." Everyone has rough days, arguments, or moments of not knowing what they want — that's normal. What sets these patterns apart is how often they happen, how intense they get, and how much they end up disrupting everyday life.
Deenz Borderline Personality Questionnaire (DBPQ) evaluates these characteristics across four key clinical dimensions: Mood & Anger, Relationships & Fear of Abandonment, Identity & Thought Patterns, and Impulse Control & Self-Harm. Utilizing a uniform 5-point agreement scale, this tool offers a structured screening of borderline traits.
Participation
This questionnaire is for adults who want a better sense of their own patterns. It also works well in educational, clinical, and research settings as a screening step. It's anonymous, and answers aren't saved after the session ends.
