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: Affective Instability & Anger, Interpersonal Instability & Abandonment, Identity & Cognitive Distortion, and Impulsivity & Self-Harm. Utilizing a combination of frequency-based Likert statements and binary True/False items, 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.

Deenz Borderline Personality Questionnaire (DBPQ) Questionnaire
Below is the Deenz Borderline Personality Questionnaire (DBPQ), a digitally adapted 54- items self-assessment questionnaire. This is a mix of true/false questions and "how often" questions about things you might think, feel, or do. Think about the last few months and pick whatever feels closest to true for you. There's no right or wrong answer here — just answer honestly, based on your own experience.
