Cohort study, 1995

# How well do three different PMS measurement tools agree with each other?

All three tools (PMSD, MDQ, and DRF) measure PMS symptoms reliably and their results correlate strongly, with correlations ranging from 0.67 to 0.81. This means the shorter PMSD tool works as well as longer questionnaires.

 Early or limited evidence

37 premenopausal women with documented PMS

## What they did

37 women with documented PMS completed three different PMS questionnaires. Researchers compared how similar the results were using statistical analysis.

## What they found

The three instruments had strong internal consistency and strong correlations between overall scores: 0.77 between PMSD and MDQ, 0.67 between PMSD and DRF, and 0.81 between MDQ and DRF.

## What it means for you

The PMS Diary (PMSD) is a short, reliable tool that doctors can easily use in clinics or research instead of longer questionnaires. The main limitation is the small sample size.
