What is the UCLA Loneliness Scale (ULS-8)?

The ULS-8 is an eight-item short form of the UCLA Loneliness Scale described by Hays and DiMatteo.
It is used as a brief measure of subjective loneliness and social isolation-related experience.

The scale includes negatively worded loneliness items and positively worded social-connection items.
Positively worded items are reverse-scored before calculating the total.

How is it scored?

Each item is scored on a 1 to 4 response scale.

For negatively worded loneliness items, higher response values contribute to a higher loneliness
score.

For positively worded items, scoring is reversed so that higher final scores consistently indicate
greater loneliness.

The original ULS-8 total score range is 8 to 32.

Interpretation direction: higher total scores indicate greater loneliness.

How should results be interpreted?

ULS-8 is a screening and monitoring measure, not a diagnosis.

Interpret the result alongside:

  • the score direction,
  • change over time,
  • the person’s stated concerns and goals,
  • mood, function, health, mobility, caring responsibilities, and social context,
  • whether loneliness is persistent, new, worsening, or already being addressed.

A higher or rising score can support a conversation about social connection, practical barriers,
support needs, and whether follow-up or referral pathways are appropriate.
