1 Before you use it

What it is

Thirteen items across three subscales — rumination, magnification and helplessness — measuring the tendency to catastrophise about pain.

When to reach for it

Persistent pain presentations, particularly where the ÖMPSQ-SF has flagged risk and you want to know what is driving it.

2 Giving it

Scoring

Thirteen items, 0–4 each, totalling 0–52. Report the three subscales as well as the total — they suggest different conversations.

What it doesn’t measure

Diagnose depression or anxiety, and it is not a mental-health assessment. Refer appropriately where distress rather than catastrophising is the finding.

3 Reading the score

Interpreting it

**A total around 30 is commonly cited as clinically relevant.

Rumination-dominant, magnification-dominant and helplessness-dominant profiles are managed differently, which is the argument for reading the subscales.

Is the change real?

No verified MCID or MDC is carried in our library for this measure, so the number on its own cannot tell you a change is real. Compare it to this patient's own baseline and say what changed functionally.

Student trap. Using the word 'catastrophising' with the patient. It sounds like a judgement — describe the thoughts, not the label.
