Internet therapy for severe premenstrual mood and emotion problems

This trial is testing an online cognitive behavioral therapy program designed specifically for premenstrual dysphoric disorder (PMDD)—a serious condition where severe mood changes, anxiety, and emotional difficulties happen during the days before your period. The therapy is delivered over the internet with support from a therapist. Researchers want to see if this targeted approach can reduce your symptoms and help you feel better during your premenstrual week.

PMDD affects many women significantly, but treatment options are sometimes limited or don't work well for everyone. This trial exists to see if this specific type of online therapy—focused on helping you manage and regulate your emotions—could be an effective, accessible way to reduce the emotional symptoms that make this time of month so difficult.
