About

With the proposed study, the investigators aim to evaluate the long-term efficacy of the open-label placebo (OLP) intervention in premenstrual syndrome (PMS) and to contribute to a broader understanding of how OLPs work. It is planned to survey participants of the intervention groups (OLP+ and OLP-) regarding symptom intensity and impairment due to PMS after the conclusion of our randomized controlled trial (RCT) and intervention provision. Additionally, it will be examined if there is a difference between the OLP group with and without a treatment rationale (OPL+ vs. OLP-) across time. More precisely, it will be investigated whether participants of the intervention groups with and without treatment rationale experience any long-term improvement.
