The aim of this study is to determine the effects of technology-based motivation education prepared according to the health belief model on obesity-related beliefs and attitudes, nutrition-exercise behaviors, self-efficacy and weight management in obese university students.

It is stated that the university period is risky in terms of acquiring negative health behaviors that may cause overweight and obesity. In addition, it is emphasized that the transition from overweight to obesity usually occurs between the ages of 18-29. There are non-formal education programs on obesity management for adolescence and adulthood. It is noteworthy that young people in the university period are not adequately represented in the current education programs, and at the same time, education programs specific to young people are limited. The aim of this study is to determine the effects of technology-based motivation education prepared according to the health belief model on obesity-related beliefs and attitudes, nutrition-exercise behaviors, self-efficacy and weight management in obese university students. This quasi-experimental pretest-posttest randomized controlled study will be carried out at Sivas Cumhuriyet University Suşehri Health College and Suşehri Timur Karabal Vocational School between February 1, 2022 and September 15, 2022. The sample of the study will consist of 84 students (experimental group n= 42 and control group n=42). A web-based technology based motivation program including motivational interviewing will be applied to the students in the experimental group. The control group will only receive web-based education on obesity. Data will be collected using Personal Information Form, Obesity Health Belief Model Scale, Nutrition-Exercise Behavior Scale, Self-Efficacy-Efficacy Scale and Website Usability Scale. physical measurements; A digital height-weight meter will be used for BMI measurement, and a tape measure will be used for waist and hip circumference. Whether the data is normal or not will be determined by Kolmogorov-Smirnov, Shapiro Wilk tests. In order to determine whether there is a difference in the research, necessary parametric and nonparametric tests will be used depending on whether the assumptions are met or any or all of the assumptions are not met.

Inclusion Criteria:

• 18-25 age range
• Body Mass Index (BMI) ≥ 25.0,
• Having internet access with a computer, tablet or mobile device.

Exclusion Criteria:

• Under 18 years old or over 25 years old,
• BMI < 25.0,
• Continuously using regular medication,
• Presence of a pre-existing health problem (having a surgical operation in the last three months, having diseases with metabolic syndrome, being diagnosed with cancer, being diagnosed with an eating disorder, being diagnosed with a psychological illness, and being physically disabled),
• Participating in any weight management program in the last three months,
• Pregnancy.

In the randomized controlled study, blinding will be done in terms of statistician and reporting. The data regarding the pre-test and post-tests will be collected by another researcher who does not know who is in the experimental and control group, and the research data will be coded and transferred to the computer environment by another researcher without specifying the experimental and control groups. The analysis of the data coded in terms of groups will be done by a statistics expert. After the statistical analyzes are made and the research report is written, the assistant researcher will explain the coding for the experimental and control groups. In this way, a single blinding application was planned for the researcher.
