Evaluation of the Validity and Reliability of a Persian Version of the Forgotten Joint Score in Patients Undergoing Total Hip Arthroplasty
ARCHIVES OF BONE AND JOINT SURGERY-ABJS(2023)
Abstract
Objectives: The increasing number of total hip arthroplasties (THA) has led to increased patient demands and expectations, making it crucial to assess patients' ability to "forget" their implants in daily life. This study aimed to determine the reliability and validity of a Persian version of the Forgotten Joint Score (P-FJS) in THA patients. Methods: The questionnaire was translated bidirectionally with the permission of the questionnaire designer. Data were collected from 2018 to 2020 and included 142 patients who had undergone THA by the same surgeon at least one year ago. Participants completed the FJS questionnaire twice within a one-week interval, and the validity, reliability, and feasibility of the questionnaires were assessed using statistical tests on the HHS and OHS forms completed by all participants. Results: In 142 patients (52.1% male) with a mean age of 65 +/- 0.5 years who answered the questionnaires, P-FJS correlated strongly with OHS and HHS. The internal consistency (alpha = 0.91) and reproducibility of the questionnaire were excellent. None of the floor and ceiling effects were detected. Conclusion: The P-FJS questionnaire in the THA is considered a legitimate, repeatable, and self-administered survey that can be compared to its English-language counterpart. In addition, it is noteworthy that this version does not show any floor or ceiling effects.
