Study, 1983

# What makes PMS research difficult?

Researchers struggle to define what PMS is and how to measure it properly.

 Early or limited evidence

Experts at a National Institute of Mental Health workshop

## What they did

Experts met at a National Institute of Mental Health workshop to discuss main problems in PMS research and ways to improve it.

## What they found

The main difficulties are: deciding time limits for the premenstrual phase, selecting a period to compare it against, determining what symptom changes count as meaningful, and establishing how consistent changes need to be. Experts agreed that PMS exists and identified ways to improve research standards.

## What it means for you

Before we can do strong PMS research, scientists need to agree on how to define and measure PMS. Without a clear definition, it's hard to do rigorous studies.
