An observational study in Nomofobia, Body Image Disturbance and Body Image, sponsored by Bahçeşehir University. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 30 Years. Per ClinicalTrials.gov, last updated 2026-04-17.
Sponsored by Bahçeşehir University · Observational
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:
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.
56 studies on the registry are indexed under Body Dysmorphic Disorders; 11 are open to participants now.
This study's planned enrollment of 150 is close to the median of 150 across 11 observational studies indexed under Body Dysmorphic Disorders.

The study population consists of university students who are active smartphone users and have provided informed consent. Participants do not have pacemakers, metallic prostheses, or pregnancy, and they do not have diagnosed metabolic disorders (e.g., Cushing's syndrome, diabetes, thyroid disorders) or psychiatric conditions that could affect eating behavior. Individuals with current eating disorders, severe psychiatric diagnoses, regular use of psychiatric medications, recent corticosteroid or hormone therapy, or those who do not complete the questionnaires and measurement procedures are excluded.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Participants (n:150) will complete questionnaires assessing nomophobia, perceived stress, body image, and food addiction. In addition, objective anthropometric measurements, including body composition (fat mass, muscle mass) via Bioelectrical Impedance Analysis (InBody 270) and waist-to-hip ratio measurements, will be collected. No drugs or treatments are administered.
Other: Questionnaires on Nomophobia, Perceived Stress, Body Image, and Food Addiction; Body Composition and Anthropometric Measurements via Bioelectrical Impedance Analysis
Participants will complete self-report questionnaires including the Nomophobia Questionnaire (NMP-Q), Perceived Stress Scale (PSS-10), Body Image Questionnaire (BIQ), Food Addiction Scale (YFAS 2.0), and the Stunkard Figure Rating Scale (FRS). Objective anthropometric measurements, including body composition using InBody 270 and waist-to-hip ratio, will also be obtained.
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).
Time frame: Baseline
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
Time frame: 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.
Time frame: 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.
Time frame: Baseline
