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.
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.
