## Quick answer

**Anxiety** and **BPD-related** experiences can both include fear, tension, and worry about relationships. That does **not** mean an MSI-BPD score can diagnose an anxiety disorder—or BPD.

## Where symptoms may overlap

People may notice:

- Constant worry or feeling “on edge”  
- Fear of being rejected or left  
- Avoiding conflict or clinging under stress  
- Sleep problems when emotions run high  

These features can belong to different clinical pictures.

## How clinicians start to distinguish

In broad strokes:

- **Anxiety disorders:** assessment looks at panic, phobias, generalized worry, obsessive-compulsive patterns, or social anxiety—depending on symptoms.  
- **BPD patterns:** assessment often includes identity disturbance, chronic emptiness, intense unstable relationships, and self-harm themes alongside emotional reactivity.  
- **Co-occurrence:** anxiety disorders and BPD traits can appear together; treatment planning is individualized.

## Why online screening cannot decide

The MSI-BPD does not map onto anxiety disorder criteria. It offers a **BPD-oriented screen** only. Bring concerns about anxiety *and* BPD-related traits to a licensed clinician rather than relying on any single online score.
