This study aims to examine the effect of peer education based on the Health Belief Model (HBM) on university students' coping skills with premenstrual syndrome (PMS). PMS is a common health problem that lowers women's quality of life and negatively affects their social and academic performance. The study will be conducted with 56 female students studying at Istanbul Atlas University, utilizing a randomized controlled design. Following the administration of a pre-test, participants diagnosed with PMS will be randomly assigned to either the intervention or control groups. The intervention group will be taught strategies for coping with PMS symptoms through peer education, while the control group will only receive an educational brochure.
The training sessions will be structured framework of the Health Belief Model and will cover topics such as the definition, causes, and risk factors of PMS, as well as healthy lifestyle habits (nutrition, exercise, stress management). Data will be collected using pre-test and post-test methods, and changes in PMS symptoms will be analyzed using SPSS software. The study is expected to increase students' awareness of PMS and strengthen their ability to cope with symptoms as a result of peer education.
The study duration is planned for 12 months and is projected to be conducted between 2025 and 2026. The intervention group will receive peer education based on the Health Belief Model framework covering topics such as the causes, symptoms, and risk factors of PMS. The training will be delivered in a classroom setting as two sessions conducted biweekly. Lecture, group discussions, and audiovisual materials will be used as educational methods.
Personal Information Form and the Premenstrual Syndrome Scale will be used as data collection tools. The scale will be first administered in the pre-test to evaluate the severity of the participants' PMS symptoms. Following random assignment, the scale will be administered three times prior to three menstrual cycles for both intervention and control groups. The obtained data will be analyzed using SPSS software, and differences between groups will be evaluated using independent samples t-test and analysis of variance (ANOVA). The statistical significance level will be accepted as p\<0.05.
The findings to be obtained from this study are expected to demonstrate the potential of the peer education method to increase PMS awareness and strengthen coping skills with symptoms. The results of the research aim to contribute to the development of health education programs targeted toward university students.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Being a female university student studying at Istanbul Atlas University. Being diagnosed with or experiencing premenstrual syndrome (PMS) according to the Premenstrual Syndrome Scale pre-test baseline score.
Volunteering to participate in the study and providing written .
Having regular menstrual cycles.
Exclusion Criteria:
Not experiencing premenstrual syndrome (PMS) based on the pre-test screening. Having a diagnosed chronic gynecological, endocrine, or psychiatric disorder that could interfere with menstrual symptoms.
Being pregnant or breastfeeding. Using hormonal or receiving hormonal therapy within the last 3 months.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Participants in this arm will not receive any peer education sessions. They will only be provided with an educational brochure containing standard information about premenstrual syndrome (PMS) and its management.
Participants in this arm will receive Health Belief Model (HBM)-based peer education regarding premenstrual syndrome (PMS). The training consists of two biweekly sessions delivered in a classroom setting, covering PMS definition, causes, risk factors, and healthy lifestyle habits (nutrition, exercise, stress management).

Change in Premenstrual Syndrome Severity
Evaluated using the Premenstrual Syndrome Scale (PMSS) to assess the severity of participants' PMS symptoms across different dimensions. The scale will be administered a total of four times: at baseline (pre-test) and prior to three consecutive menstrual cycles (post-tests) to observe changes over time. Higher scores on the scale indicate a higher severity of premenstrual syndrome symptoms.
Time frame: Baseline (pre-test) and monthly prior to three consecutive menstrual cycles (over a period of 3 months post-intervention)
Plan to share: Yes — De-identified individual participant data underlying the results reported in the future publication of this study will be made available to qualified researchers. Data will be shared strictly for academic research purposes and systematic reviews to ensure transparency. Requests should be directed to the corresponding investigator via email, accompanied by a sound research proposal.

Ran from Jan 2026 to primary completion in May 2026, 4 months.
Of 76 non-industry interventional studies with no phase under Premenstrual Syndrome, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 12. This study's 4 months is below that.
Counting every sponsor, half of 87 studies reached it within 5 months; a quarter within 3 and three quarters within 10.
