Clinical context: when LOT-R is used

10-item measure of dispositional optimism with 4 filler items. LOT-R is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.

Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.

How to score LOT-R: 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.

Step 1 — Score each item

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
1In uncertain times, I usually expect the bestNeutral2
2It's easy for me to relax (filler)Strongly disagree0
3If something can go wrong for me, it willNeutral2
4I'm always optimistic about my futureNeutral2
5I enjoy my friends a lot (filler)Strongly disagree0
6It's important for me to keep busy (filler)Strongly disagree0
7I hardly ever expect things to go my wayDisagree3
8I don't get upset too easily (filler)Strongly disagree0
9I rarely count on good things happening to meStrongly disagree4
10Overall, I expect more good things to happen to me than badAgree3

Step 2 — Add up the scores

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

2 + 0 + 2 + 2 + 0 + 0 + 3 + 0 + 4 + 3 = 16

Step 3 — Look up the band

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

Total = 16 falls between 13 and 18Moderate

Step 4 — What does this mean clinically?

Moderate. Monitor

A score is one input alongside history and examination. LOT-R supports clinical judgment — it does not replace it.
