Peer Education Based on Integrated Change Model on Nursing Students' STI-Related Behaviors

This study aims to compare the effectiveness of two peer education models on nursing students' behaviors, attitudes, and knowledge regarding sexually transmitted infections (STIs).

First-year nursing students will be randomly assigned to one of two groups. The intervention group will receive a peer education program developed based on the Integrated Change Model (ICM), while the control group will receive standard peer education. Both programs will be delivered by a fourth-year nursing student (peer educator) in four weekly sessions of 30 minutes each.

The ICM integrates key principles from major behavior change theories including the Theory of Planned Behavior, Social Cognitive Theory, the Transtheoretical Model, and the Health Belief Model. By combining peer education with this theoretical framework, the study seeks to promote lasting positive changes in STI-related protective behaviors among nursing students.

Data will be collected using validated scales measuring STI-related behaviors, attitudes, and knowledge before and after the intervention. The study will contribute to the development of more effective STI prevention programs in university settings.

Treatment and study plan

ICM-Based Peer Education Program

Behavioral

A 4-session peer education program developed based on the Integrated Change Model (ICM). Sessions cover: (1) STI awareness and types, (2) reliable information sources and prevention methods, (3) myths and communication skills, (4) barriers and action planning. Each session lasts 30 minutes and is delivered weekly by a trained fourth-year nursing student peer educator.

Other names: Intervention Group (ICM-Based Peer Education)

Standard Peer Education Program

Behavioral

A 4-session standard peer education program on sexually transmitted infections (STIs). Content includes STI types, transmission routes, prevention methods, and safe sexual behaviors. Each session lasts 30 minutes and is delivered weekly by the same trained fourth-year nursing student peer educator using presentation and discussion methods.

Other names: Control Group (Standard Peer Education)

Primary outcomes

STI-Related Protective Behaviors

Time frame: Baseline (Week 0) and immediately after the intervention (Week 4)

Measured by the Scale for Behaviors Towards Protection from Sexually Transmitted Diseases (21 items, 5-point Likert scale; score range 21-105). Higher scores indicate better STI-protective behaviors. Cronbach's alpha=0.91.
