How to score UCLA-LS-3: a step-by-step worked example

This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.

Read each question and choose the response that best fits. Each response has a number next to it — that number is the item's score. The example below uses illustrative answers.

#ItemExample responseScore

Step 2 — Add up the scores

Add up all the item scores you noted in Step 1.

2 + 2 + 3 = 7

Step 3 — Look up the band

Find the row in the interpretation table whose range contains your total:

Total = 7 falls between 6 and 7Moderate loneliness

Step 4 — What does this mean clinically?
