EHBM-Based Intervention for Polycystic Ovarain Syndrome Among High Female School Students (EHBM-PCOSHSFS)

September 8, 2026 updated by: Salwan Abed Laftah

Efficacy of The Expanded Health Belief Model-Based Intervention in Enhancing Female High School Students' Adherence to Polycystic Ovary Syndrome Health-Protective Behaviors: A Randomized Controlled Trial

This study aims to examine efficacy of The Expanded Health Belief model-based intervention in enhancing female high school students' adherence to polycystic ovary syndrome health-protective behaviors.

Study Overview

Detailed Description

The study will involve female high school students and use a Randomized Controlled Trial (RCT) design. Participants will be randomly assigned to an intervention group receiving an educational/behavioral program based on the Expanded Health Belief Model, and a control group receiving usual or routine information.

The intervention will aim to improve students':

Knowledge and awareness about PCOS Perceived susceptibility and severity of PCOS Perceived benefits and barriers to preventive behaviors Self-efficacy and motivation Adherence to healthy behaviors, such as healthy eating, regular physical activity, weight management, and appropriate health-seeking behaviors The effectiveness of the intervention will be assessed by comparing changes in PCOS-related health-protective behaviors between the intervention and control groups.

  • Are currently participating in another structured lifestyle, weight-management, or PCOS educational program.
  • Are receiving a treatment or intervention that could substantially influence the study outcomes.
  • Are absent from a predetermined proportion of intervention sessions (for example, more than 20%-25%).
  • Fail to complete the baseline assessment or required post-intervention assessment.
  • Withdraw their consent/assent at any stage of the study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental

the experimental group consists of female high school students who are randomly assigned to receive the Expanded Health Belief Model (EHBM)-based intervention.

The intervention is designed to improve their understanding of Polycystic Ovary Syndrome (PCOS) and encourage them to adopt and maintain health-protective behaviors.

The experimental group would receive a structured educational/behavioral program addressing the major components of the EHBM, such as:

Perceived susceptibility: Helping students understand their potential risk factors for PCOS.

Perceived severity: Increasing awareness of the possible health consequences of PCOS.

Perceived benefits: Explaining the benefits of healthy behaviors in preventing or reducing PCOS-related risks.

Perceived barriers: Identifying and overcoming obstacles to healthy eating, physical activity, and other protective behaviors.

Self-efficacy: Building students' confidence in their ability to practice healthy behaviors.

This is a non-pharmacological, behavioral intervention designed to enhance adherence to polycystic ovary syndrome (PCOS) health-protective behaviors among female high school students. The intervention is based on the Expanded Health Belief Model and consists of structured educational and behavioral sessions addressing key determinants of preventive health behaviors. The intervention includes education about PCOS, increasing perceived susceptibility and severity, emphasizing the benefits of health-protective behaviors, identifying and reducing perceived barriers, enhancing self-efficacy, providing cues to action, and strengthening health motivation. Practical guidance on healthy dietary practices, regular physical activity, healthy weight management, and appropriate health-seeking behaviors is also provided to support participants in adopting and maintaining PCOS health-protective behaviors.
No Intervention: Control group

If by "non-interventional group" you mean the control group in your randomized controlled trial, it is the group that does not receive the Expanded Health Belief Model (EHBM)-based intervention.

Control (Non-intervention) Group The control group consists of female high school students who are randomly assigned not to receive the specific EHBM-based educational intervention during the study period.

They may continue to receive their usual school health education or routine information about general health, depending on the study protocol.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adherence to Polycystic Ovary Syndrome Health-Protective Behaviors
Time Frame: 6 months

Number of female high school students who would adhere to Polycystic Ovary Syndrome Health-Protective Behaviors as measured by the Behavioral Intention Scale to Adhere to Polycystic Ovary Syndrome Health-Protective Behaviors.

The data will be collected using a self-reported tool. The Behavioral Intention Scale to Adhere to Polycystic Ovary Syndrome Health-Protective Behaviors includes the Dietary Intention subscale which encompasses 3 items (it ranges between 3-15).

The Physical Activity Intention Subscale which encompasses 2 items (it ranges between 2-10).

The Medical Engagement and Monitoring Intentions which encompasses 3 items (it ranges between 3-15).

All these items are measured on a 5-point Likert scale.
