About this study
Official title: An Investigation of the Relationships Between Nomophobia Levels and Stress, Body Image and Food Addiction Among University Students
The purpose of this study is to examine the effects of nomophobia levels on stress, food addiction, and body image among undergraduate students aged 18-30 at Bahçeşehir University, Faculty of Health Sciences. The primary questions it aims to answer are:
- Is there a statistically significant relationship between nomophobia levels and perceived stress, food addiction, and body image among university students?
- Is there a correlation between objective anthropometric data (body fat percentage, skeletal muscle mass) measured via Bioelectrical Impedance Analysis (BIA), waist/hip circumference measurements, and the individual's perceived body image?
Read the detailed description
The data collection process for this study will involve undergraduate students aged 18-30 at Bahçeşehir University, Faculty of Health Sciences. Participants will first complete a survey consisting of a socio-demographic form, daily screen time tracking, the Nomophobia Questionnaire (NMP-Q), the Perceived Stress Scale (PSS-10), the Yale Food Addiction Scale (YFAS), and the Stunkard Figure Rating Scale (FRS) to assess subjective body image.To ensure the accuracy of the biological data, participants will be required to follow a standardized measurement protocol, including at least 8 hours of fasting, avoidance of heavy physical activity prior to the assessment, and the removal of all metal accessories. Under these conditions, objective physical data will be gathered using the InBody 270 body composition analyzer via Bioelectrical Impedance Analysis (BIA) to record body weight (kg), body fat percentage (%), and skeletal muscle mass (kg). Additionally, anthropometric measurements including waist and hip circumferences (cm) will be manually collected using a standardized non-elastic tape to calculate Body Mass Index (BMI) and Waist-to-Hip Ratio (WHR). These objective metrics will be compared with the participants' subjective survey responses to analyze the impact of nomophobia on body image distortion, stress levels, and eating behaviors.

What is being measured
The primary outcome is the main question the study is designed to answer.
Nomophobia
The level of nomophobia experienced by participants, measured using the Nomophobia Questionnaire (NMP-Q).
This form aims to assess your feelings and thoughts when you cannot access your smartphone or are away from it, a condition known as nomophobia. There are no right or wrong answers; what matters is answering honestly based on your own experience. Indicate your level of agreement with each statement about your smartphone use (1 = strongly agree, 7 = strongly disagree).
Measured: Baseline
Secondary outcomes (3)
Perceived Stress
The level of stress perceived by participants, measured using the Perceived Stress Scale (PSS).
Below are a series of questions about your personal experiences over the past month. Please read each question carefully and mark the box under the option that best reflects you. There are no right or wrong answers; what matters is that you respond in a way that reflects your own feelings and thoughts.
Never - Almost Never - Sometimes - Quite Often - Very Often
Measured: Baseline
Body Image
Self-perceived body image assessed using the Stunkard Figure Rating Scale (FRS), where participants select a figure that best represents their current and ideal body shape.
The images in this section are designed to assess individuals' body perception. Below are figures representing different body types. Please examine these figures carefully and select the one that you think best represents you at the moment. There are no right or wrong answers in this study; what matters is reflecting your own perception as accurately as possible.
Measured: Baseline
Food Addiction
Assessment of addictive eating behaviors using the Yale Food Addiction Scale 2.0 (YFAS 2.0).
This questionnaire asks about your eating habits over the past year. People sometimes have difficulty controlling their intake of certain foods, such as;
- Sweets like ice cream, chocolate, pastries, cookies, cake, and candy
- Starches such as white bread, bread, pasta, and rice
- Salty snacks like chips, pretzels, and crackers
- Fatty foods such as steak, bacon, hamburgers, cheeseburgers, pizza, and French fries
- Sugary drinks like soda and fruit juice
When the following questions refer to SPECIFIC FOODS, please think of ANY foods similar to those listed in each category, or ANY OTHER foods that you may have had problems with during the past year.
Measured: Baseline
