PDI · Pain Disability Index

7 items · 3 min · 0–70 · lower is better

1 Before you use it

What it is

Seven life domains, each rated 0–10 for how much pain disrupts it — family and home responsibilities, recreation, social activity, occupation, sexual behaviour, self-care, and life-support activity.

Three minutes, and it covers ground most disability indices don't.

When to reach for it

Persistent pain in any region, particularly where a region-specific index doesn't capture the life impact.

2 Giving it

Scoring

Seven items, 0–10, totalling 0–70. Higher means more disability.

What it doesn’t measure

Pain intensity, fear, or self-efficacy.

3 Reading the score

Interpreting it

Read domain by domain. The domains scoring highest are the goals.

Is the change real?

MCID 13 points overall, but 7 to 20 depending on how disabled they were to start with. MDC 7 points. Compare the change against this patient's own baseline as well as the figure. SourceMeasured in chronic pain.

Student trap. Skipping the sexual behaviour item because it's awkward. Either ask properly or record that it wasn't completed — don't silently score around it.
