Design outcomes

Primary

MeasureTime frameDescription
Change in Menstrual Symptoms Questionnaire (MSQ) ScoresBaseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)Change from baseline in menstrual symptom severity as measured by the validated 24-item Menstrual Symptoms Questionnaire (MSQ). Rated on a 5-point Likert scale (Never, Rarely, Sometimes, Often, Always). Higher scores indicate greater symptom severity.

Secondary

MeasureTime frameDescription
Symptom Severity RatingsBaseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)Self-report rating of the severity of 13 common menstrual cycle-related symptoms experienced during their most recent menstrual cycle. Each item is scored on a 5-point Likert scale (Not noticeable, Barely noticeable, Moderate, Distracting, Severe). The questionnaire assesses 7 physical symptoms (fatigue, bloating, breast tenderness, headaches, cramps, body aches, food cravings) and 6 psychological symptoms (anxiety, irritability, mood swings, crying spells, concentration difficulties, low mood). Higher scores indicate greater symptom severity.
Proportion of participants with perceived reduction in menstrual cycle symptomsBaseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)Participants are asked how much they agree or disagree with 18 statements about the test product reducing symptoms, for example: "The test product reduces the severity of my menstrual symptoms", "The test product reduces the duration of my menstrual symptoms", "The test product reduces the amount of mood swings I have related to my period", "The test product reduces my menstrual cramps". Response options: Strongly agree, Agree, Neither agree or disagree, Disagree, Strongly disagree
