What this trial studies

This is a parallel, two-group randomized controlled trial that will assign about 164 women meeting DSM-5 criteria for PMDD to either an 8-week therapist-guided internet-delivered CBT program with emotion-regulation components or to a waitlist control, with 1:1 allocation. Participants are screened via an online questionnaire, a diagnostic telephone interview, and two prospective menstrual cycles of daily symptom ratings using the DRSP before and after treatment. Primary outcomes compare pre- to post-treatment changes in luteal-phase premenstrual symptoms and functional impairment measured prospectively and retrospectively, and secondary outcomes include quality of life and difficulties in emotion regulation. The intervention is self-help ICBT with therapist guidance delivered remotely in Swedish from Uppsala University investigators.

Who should consider this trial

Good fit: Ideal candidates are women aged 18–45 who meet DSM-5 criteria for PMDD, have regular cycles (23–34 days), can read Swedish, and have internet access on a computer or mobile device.

Not a fit: People who are pregnant or breastfeeding recently, have recent changes in psychotropic or hormonal treatments, have complicating gynecological diseases, are receiving concurrent psychotherapy for premenstrual problems, or have severe psychiatric disorders or elevated suicide risk are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this could provide an accessible non-drug treatment that reduces luteal-phase symptoms and improves daily functioning for women with PMDD.

How similar studies have performed: Preliminary research suggests internet-delivered CBT can help PMDD symptoms, but adding targeted emotion-regulation components is a relatively new approach that needs more evidence.
