A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Undergraduate students aged 18–30 at Bahçeşehir University will complete questionnaires including the Nomophobia Questionnaire (NMP-Q), Perceived Stress Scale (PSS-10), Yale Food Addiction Scale (YFAS), and the Stunkard Figure Rating Scale (FRS), along with a sociodemographic form and daily screen-time tracking. Objective body composition data (body weight, body fat percentage, skeletal muscle mass) will be collected using the InBody 270 via bioelectrical impedance analysis after standardized preparation, and waist and hip circumferences will be measured manually to compute BMI and waist-to-hip ratio. The study will compare subjective perceptions of body image and eating behavior with objective anthropometric measures to explore relationships with nomophobia levels. Data analysis will focus on correlations between nomophobia and perceived stress, food addiction scores, and body image distortion, and on how objective measures relate to subjective body-image perceptions.
