About this study

Official title: More Than Just p-Values: Minimal Clinically Important Difference for the Visual Analog Scale, Menstrual Symptom Questionnaire and Functional and Emotional Measure of Dysmenorrhea in Patients With Primary Dysmenorrhea

The aim of this study is to determine the Minimal Clinically Important Difference (MCID) for the Visual Analog Scale (VAS), Menstrual Symptom Questionnaire (MSQ), and Functional and Emotional Measure of Dysmenorrhea (FEMD) in patients with primary dysmenorrhea (PwPD).

Read the detailed description

100 PwPD will receive functional exercises three times a week for three menstrual cycles. Patients will be assessed on the most painful days of the first (baseline), second, and third menstrual cycles. The receiver operating characteristics (ROC) method and Gamma coefficient analysis will be applied to determine the responsiveness.

  • Exercise TreatmentOther

    In this study, a functional exercise programme will be performed 3 days a week for 8 weeks in three cycles as previously recommended. This programme consisted of a 5-minute warm-up and a 45-minute exercise phase.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain Intensity

    Pain intensity in the lower abdomen, lower back and both thighs will be assessed using a 10 cm Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (excruciating pain). Pain levels were categorised as 0-2 (safe), 3-5 (acceptable) and 6-10 (risky).

    Measured: Baseline (On the most painful day of the menstrual cycle before the intervention)

  2. Pain Intensity

    Pain intensity in the lower abdomen, lower back and both thighs will be assessed using a 10 cm Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (excruciating pain). Pain levels were categorised as 0-2 (safe), 3-5 (acceptable) and 6-10 (risky).

    Measured: After the 4-week intervention (On the most painful day of the first menstrual cycle after the start of the intervention)

  3. Pain Intensity

    Pain intensity in the lower abdomen, lower back and both thighs will be assessed using a 10 cm Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (excruciating pain). Pain levels were categorised as 0-2 (safe), 3-5 (acceptable) and 6-10 (risky).

    Measured: After the 8-week intervention (On the most painful day of the second menstrual cycle after the start of the intervention)

Secondary outcomes (8)
  1. Menstrual Symptom Questionnaire (MSQ)

    The Likert scale consists of 22 items, with responses rated on a 5-point range from 1 (never) to 5 (always). The scale includes three components: 'Negative Effects/Somatic Complaints' (items 1-13), 'Menstrual Pain Symptoms' (items 14-19), and 'Coping Methods' (items 20-22). The MSQ score is the mean value of all items in the scale. Increasing scores reflect more menstrual symptoms.

    Measured: Baseline (On the most painful day of the menstrual cycle before the intervention)

  2. Menstrual Symptom Questionnaire (MSQ)

    The Likert scale consists of 22 items, with responses rated on a 5-point range from 1 (never) to 5 (always). The scale includes three components: 'Negative Effects/Somatic Complaints' (items 1-13), 'Menstrual Pain Symptoms' (items 14-19), and 'Coping Methods' (items 20-22). The MSQ score is the mean value of all items in the scale. Increasing scores reflect more menstrual symptoms.

    Measured: After the 4-week intervention (On the most painful day of the first menstrual cycle after the start of the intervention)

  3. Menstrual Symptom Questionnaire (MSQ)

    The Likert scale consists of 22 items, with responses rated on a 5-point range from 1 (never) to 5 (always). The scale includes three components: 'Negative Effects/Somatic Complaints' (items 1-13), 'Menstrual Pain Symptoms' (items 14-19), and 'Coping Methods' (items 20-22). The MSQ score is the mean value of all items in the scale. Increasing scores reflect more menstrual symptoms.

    Measured: After the 8-week intervention (On the most painful day of the second menstrual cycle after the start of the intervention)

  4. Functional and Emotional Measure of Dysmenorrhea (FEMD)

    The FEMD is a 14-item measurement tool that evaluates the functional and emotional aspects of dysmenorrhea using a 5-point Likert-type scale. The total scores on this scale range from 14 to 70, with higher scores indicating a more significant functional and emotional impact of dysmenorrhea on an individual.

    Measured: Baseline (On the most painful day of the menstrual cycle before the intervention)

  5. Functional and Emotional Measure of Dysmenorrhea (FEMD)

    The FEMD is a 14-item measurement tool that evaluates the functional and emotional aspects of dysmenorrhea using a 5-point Likert-type scale. The total scores on this scale range from 14 to 70, with higher scores indicating a more significant functional and emotional impact of dysmenorrhea on an individual.

    Measured: After the 4-week intervention (On the most painful day of the first menstrual cycle after the start of the intervention)

  6. Functional and Emotional Measure of Dysmenorrhea (FEMD)

    The FEMD is a 14-item measurement tool that evaluates the functional and emotional aspects of dysmenorrhea using a 5-point Likert-type scale. The total scores on this scale range from 14 to 70, with higher scores indicating a more significant functional and emotional impact of dysmenorrhea on an individual.

    Measured: After the 8-week intervention (On the most painful day of the second menstrual cycle after the start of the intervention)

  7. Global Rating Change (GRC)

    The GRC comprised seven responses, ranging from 1 to 7, indicating "very much better," "much better," "slightly better," "no change," "slightly worse," "much worse," and "very much worse," respectively.

    Measured: After the 4-week intervention (On the most painful day of the first menstrual cycle after the start of the intervention)

  8. Global Rating Change (GRC)

    The GRC comprised seven responses, ranging from 1 to 7, indicating "very much better," "much better," "slightly better," "no change," "slightly worse," "much worse," and "very much worse," respectively.

    Measured: After the 8-week intervention (On the most painful day of the second menstrual cycle after the start of the intervention)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain Intensity (time frame: Baseline (On the most painful day of the menstrual cycle before the intervention)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06835036, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
