• Orthorexia nervosa
• ORTHO-15 test
• Young adults

There is a lack of Polish tools to measure behaviour related to orthorexia nervosa. The purpose of the present study was to validate the Polish version of the ORTHO-15 test.
341 women and 59 men (N = 400) were recruited, whose age ranged from 18 to 35 years. Mean age was 23.09 years (SD = 3.14) in women and 24.02 years (SD = 3.87) in men. The ORTHO-15 test and the EAT-26 test were used in the present study.
Factor analysis (exploratory and confirmatory analysis) was used in the present study. Exploratory factor analysis performed on the initial 15 items from a random split half of the study group suggested a nine-item two-factor structure. Confirmatory factor analysis performed on the second randomly selected half of the study group supported this two-factor structure of the ORTHO-15 test. The Polish version of the ORTHO-15 test demonstrated an internal consistency (Cronbach's alpha) equal to 0.644.
The Polish version of the ORTHO-15 test is a reliable and valuable instrument to assess obsessive attitudes related to healthy and proper nutrition in Polish female and male population.
