Sexually transmitted infections (STIs) are an important public health problem as they affect more than 1 million people worldwide every day. The extent of sexually transmitted diseases is still unknown due to underreporting, underdiagnosis or asymptomatic course of these diseases. When the literature is examined, it is seen that the incidence of STD has increased in recent years. The prevalence of premarital sexual intercourse as a result of the decrease in the age of sexual maturity but the increase in the age at marriage in general plays an important role in this increase. It is estimated that 46.8 million of 450 million people in the 15-49 age group living in the European region, including Turkey, have treatable STIs. STD can lead to many serious health problems such as infertility, ectopic pregnancy, cancer, chronic pelvic pain, pelvic adhesions and even death. Moreover, eye diseases, central nervous system infection and death may occur in the baby of an infected mother. In the report of the "Study on Sexual and Reproductive Health in Young People" conducted in Turkey in 2007, it was determined that young people do not have sufficient information about the reproductive organs, structure and physiology, health problems that may arise due to STD, HIV/AIDS, and ways of protection (6).An effective education; can significantly affect the quality of care, personal safety and satisfaction. One of the most effective and successful methods used in education is the Teach-Back method. Tell What You've Learned is a communication and education method used in health education for patients to remember and understand important information about diagnosis, treatment, medications or care. Tell What You've Learned is explained as a method that can be easily used for almost any interaction between healthcare team members and patients and can strengthen team understanding. It is recommended that all personnel, not only clinical caregivers, should use the method effectively in the health care system. It is stated that the conceptual framework of this method is based on the individuals receiving health services to present the information by arranging them according to themselves. It is considered as an effective method in terms of determining whether the transferred information is understood correctly.

It is stated that 40-80% of the individuals who consult or immediately forget the information given to them about their health. Various factors that cause communication problems between healthcare professionals and clients during information transfer affect the clarity and permanence of the information given.The "Tell What You Have Learned" method is also expressed as closing the loop, and it is reported to be an effective method when used to eliminate the communication gap between healthcare professionals and service recipients. In addition, it is stated that the use of the method to control the materials (educational brochure, training guide, etc.) used by individuals leaving the hospital to access health information will have a positive effect on health outcomes. From another point of view; It is predicted that it will increase the health literacy rate, and it is accepted as a research-based health literacy intervention that enriches the communication between the health care provider and the service recipient, improves the health outcomes of the individual.

Purpose of the research; The aim of this study is to examine the effects of the education given to women of reproductive age to protect themselves from sexually transmitted diseases on their behaviors.

The data will be evaluated using the SPSS 22.0 statistical package program. The construct validity of the scale will be examined using the SPSS AMOS program. Sample adequacy will be determined by Kaiser-Meyer-Olkin (KMO) analysis, the suitability of the sample for factor analysis will be determined by Barlett's Test analysis, and explanatory and confirmatory factor analysis will be performed. Internal consistency of the scale, Cronbach's Alpha coefficient, the effect of each item on the total score, item-total correlation coefficients, whether the scale is an additive scale or not. Tukey will be determined by a splicability test. The final form of the scale will be created from the items with the highest reliability.

Tests planned to be used in the analysis of the data, Single Sample Kolmogorov Smirnov Test for examining the conformity of numerical variables with normal distribution, Student's t test for comparing quantitative variables with normal distribution among women, and comparing non-normally distributed quantitative variables.

Mann Whitney U test and Chi-square test will be used to compare categorical data.
