Validity and Reliability of the Persian Version of the Forgotten Joint Score-12 Questionnaire in Iranian Patients Following Anterior Cruciate Ligament Reconstruction
Bibliographic record
Abstract
Background and Objectives: Forgotten Joint Score-12 is a useful questionnaire to evaluate the level of joint awareness and patients’ ability to forget the involved joint. The objective of the present study was to obtain a tool to evaluate the level of joint awareness for use in Persian-speaking patients following anterior cruciate ligament reconstruction. Methods: The present study was a methodological study in the field of psychometrics, in which after translation and cross-cultural adaptation of the FJS-12 questionnaire according to the ISPOR method, to examine its validity, the questionnaire was given to 114 participants who had passed between 1 and 3 years of their anterior cruciate ligament reconstruction. To evaluate reliability, participants were asked to complete and resubmit the questionnaire after a week. In this study, the intraclass correlation coefficient (ICC) was used to analyze the repeatability of the questionnaire and measure Cronbach’s alpha internal consistency. Structural validity was performed by calculating the correlation between the FJS-12 questionnaire and Western Ontario McMaster Osteoarthritis (WOMAC) and Knee Osteoarthritis Outcome Score (KOOS) questionnaires using Spearman’s correlation coefficient. The level of ceiling and floor effect of the questionnaire was also assessed. Results: Internal consistency and data repeatability were excellent for FJS-12 (Cronbach’s α=0.950 and ICC=0.845, respectively). In examining the validity, a weak to moderate correlation was obtained between the score of the FJS-12 questionnaire and the scores of the subscales of WOMAC (r=0.34) and KOOS (r=0.34). Also, a moderate correlation was obtained between the score of the FJS-12 questionnaire and the first question of the subscale of quality of life in the KOOS questionnaire (r=0.46), which indicates the validity of the average structure of the questionnaire. The floor (4.45%) and ceiling (3.50%) effect was low. Conclusion: According to the results of this study, the Persian version of the FJS-12 questionnaire can be used by Persian speakers. Also, this questionnaire is a reliable and valid tool to evaluate the level of joint awareness in individuals following anterior cruciate ligament reconstruction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
