Randomised trial, 1999
Which symptom rating scales best measure PMDD?
Three simple rating scales reliably measure PMDD symptoms and track treatment effects. They work well together, with strong agreement between them (correlations 0.70 to 0.82).
What they did
Researchers tested three different symptom rating scales at the beginning and during treatment in women with PMDD.
What they found
All three scales strongly correlated with each other (correlation range 0.70 to 0.82). All scales detected symptom worsening and showed treatment effects (P < 0.001).
What it means for you
Simple rating scales can reliably measure PMDD symptoms and whether treatment works. The study does not specify how many women were tested, which limits certainty.
