12Published measure

Highly Sensitive Person Scale

Answer each statement according to how well it describes you, from 1 (not at all) to 7 (extremely).

Questions inquire about sensory overload and sensitivity. You may pause at any time.

Psychometric Foundation and Rigor

Scientific Framework of the Instrument

Understand how this instrument is structured, its scoring rubrics, and the empirical research validating its methodology.

Evaluated Dimensions

The HSP-12 is the validated short-form measure of Sensory Processing Sensitivity (SPS) pioneered by Dr. Elaine Aron and Michael Pluess.

Ease of Excitation (EOE): Susceptibility to being overwhelmed by external demands, multitasking, and rapid changes.

Aesthetic Sensitivity (AES): Deep resonance with art, music, nature, and delicate environmental nuances.

Low Sensory Threshold (LST): Intense physical reactivity to loud noises, harsh lighting, textures, and sensory overload.

The Three Sensitivity Groups

Calculated as the overall mean of 12 items on a 1 to 7 scale, mapping to empirical sensitivity categories.

Score Level / Criteria Psychometric Interpretation
1.00 - 3.60 Dandelion (Low sensitivity) High environmental resilience and lower vulnerability to sensory overload.
3.70 - 4.60 Tulip (Medium sensitivity) Moderate sensitivity; balanced environmental receptivity and adaptability.
4.70 - 7.00 Orchid (High sensitivity / HSP) Pronounced neurosensory depth, deep empathy, and high perceptual nuance.

Frequently Asked Questions

What is Sensory Processing Sensitivity (SPS)?

It is an innate temperament trait present in 20-30% of humans involving deeper neurobiological processing of sensory and emotional input.

Is being highly sensitive a psychological disorder?

No. It is a normal, evolutionary preserved personality trait found across more than 100 animal species.

What do the Dandelion, Tulip, and Orchid categories mean?

Research by Pluess defines dandelions as thriving in nearly any environment, while orchids are sensitive to conditions but achieve remarkable flourishing in supportive settings.

Are my answers private?

100% private and computed in local memory.
