The purpose of this study was to investigate adaptation, validity, and reliability of the Turkish version of the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JOAHDEQ).

There are a number of medical assessment tools for various diseases, but in most cases such tools are designed to reflect the perspective of healthcare providers, not perspective of patients. In addition to clinical results, it is necessary to evaluate the quality of life of patients when measuring the effect of medical treatments. Thus, evaluation criteria which can be useful as patient-reported outcome indices, have received increasing attention in recent years. Health-related quality of life provides a patient-reported assessment. Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JOAHDEQ) evaluates quality of life related to hip disorders. It is also a guide in determining the expectations of individuals in the treatment process. It consists of 3 subscales (pain, movement and mental) and 20 items. Hip condition and pain are evaluated with a 100 mm scale. 20 items are scaled likert with values between 0 and 4. "0" means "strongly agree", "1" means "agree", "2" means "uncertain", "3" means "disagree" and "4" means "strongly disagree". The study is planned with 105 individuals with hip disease. After questioning the sociodemographic characteristics of the individuals, the patients will be asked to fill in JOAHDEQ, Oxford Hip Score, International Hip Outcome Tool-12, Short Form-36, and Visual Analog Scale Test-retest will be re-applied to those of the same individuals who can be reached after 1 week. The results will be analyzed using the SPSS version 22.0 computer package program.
