UCLA Loneliness Scale Information
MindCheck Tools does not reproduce, administer, score, or interpret the UCLA Loneliness Scale. This page explains the measure's purpose and the permission boundary while keeping the established URL publicly useful.
Quick answer
- What is this?
- An educational overview of the UCLA Loneliness Scale, its research purpose, limitations, and public-use permission boundary.
- Who is it for?
- People seeking reliable context about loneliness research or a separately permitted symptom self-check.
- Bottom line
- A public commercial-web permission grant is not on file. This page has no questionnaire, score, cutoff, or personal loneliness result and cannot provide a diagnosis.
Why the public questionnaire is not provided
The author-controlled UCLA resource permits use without permission for specified nonprofit research purposes. That statement does not grant a commercial public website the right to reproduce and score the scale for consumers.
MindCheck Tools has not archived written permission covering public electronic administration, automated scoring, traffic, adaptations, or the site's commercial context.
Until that permission exists, this route remains informational and withholds questionnaire text, response choices, scoring, thresholds, and respondent-facing interpretation.
What the scale was designed to measure
The UCLA Loneliness Scale is used in research to measure subjective loneliness: the perceived gap between the social connection a person wants and experiences.
Loneliness and objective social isolation are related but not identical. A research score is not a diagnosis and should not be used by itself to make medical, employment, educational, or relationship decisions.
Separately permitted, non-equivalent options
These links serve different purposes and cannot reproduce, replace, or be compared with this instrument. Each option has its own scope, timeframe, limitations, and interpretation.
Privacy boundary
This page does not ask for symptoms or experiences, collect answers, calculate a score, or produce a personal result. If you open another self-check, review its limits and the privacy policy before answering, especially on a shared device.
If you need immediate help
An informational page or self-check cannot assess an emergency. In the United States, call or text 988 for the Suicide & Crisis Lifeline, or call 911 for immediate danger. Outside the United States, use local emergency or crisis services.

Frequently asked questions
What is the UCLA Loneliness Scale?
It is a self-report research measure developed to study subjective loneliness and perceived social disconnection. The author-controlled UCLA page describes its research use and available versions.
Can I take the UCLA Loneliness Scale on MindCheck Tools?
No. The author's published permission covers specified nonprofit research uses, but MindCheck Tools has not obtained a written grant for this public consumer website and commercial-site context.
Why does this page omit questions, scoring, and a loneliness cutoff?
Those materials are not reproduced without the appropriate rights grant. The research measure also does not provide a universal diagnostic cutoff for an individual's loneliness or mental health.
Are K6 or PHQ-4 replacements for the UCLA Loneliness Scale?
No. They screen different symptom domains and do not measure or score loneliness. They are linked only as separately permitted options for people concerned about distress, depression, or anxiety.
Does feeling lonely mean I have a mental health diagnosis?
No. Loneliness is an experience, not a diagnosis by itself. Persistent distress or changes in daily functioning can be discussed with a qualified healthcare professional.
