220 people aged between 20-65 are planned to be included in the study. The data obtained from the study will be analyzed with appropriate statistical methods.~In addition, a previously valid and reliable Musculoskeletal System Health Inquiry (MIS-SS) questionnaire, which evaluates the musculoskeletal problems of individuals included in the Study, will be applied. It will be evaluated whether the results of the data obtained from the Back Pain and Body Posture Assessment Instrument for Adults (BackPDE-Y), which we have validated in Turkish, and the results of the data obtained from the Musculoskeletal Health Questionnaire (CIS-SS) questionnaire are consistent with each other.
The Adult Back Pain and Body Posture Assessment Instrument (BackPDE-Y), whose validity and reliability is planned, will be applied. This assessment scale will be translated into Turkish by two native Turkish speakers, one who is fluent in English.
