“…However, although the IKDC/Pedi-IKDC and SANE do not assess constructs identical to ACL-RSI (self-reported function vs confidence), these questionnaires have been validated in this population, and self-reported confidence can be expected to moderately or strongly correlate with self-reported function. 8,10,17 Third, a small subset of patients received the IKDC instead of the Pedi-IKDC because they were >18 years at the time of RTS testing. However, these patients were 18 or younger at the time of surgery and were included in the analysis given previous work indicating the strong positive correlation between the Pedi-IKDC and IKDC in adolescents.…”

Background: The Anterior Cruciate Ligament–Return to Sport after Injury (ACL-RSI) scale is a 12-item questionnaire assessing psychological readiness to return to sport after anterior cruciate ligament reconstruction. It has been validated for use in adults in multiple languages and in an abbreviated 6-question short form. Additionally, literature has been published using this scale in pediatric and adolescent populations, however it has not yet been validated for use with them. Purpose: To validate the ACL-RSI scale for use with pediatric and adolescent patients. Study Design: Cohort study (Diagnosis); Level of evidence, 2. Methods: Scores of 6- and 12-item ACL-RSI scales for patients undergoing return-to-sport readiness testing 6 to 8 months after anterior cruciate ligament reconstruction were analyzed. Convergent validity testing was performed against the International Knee Documentation Committee (IKDC)/Pediatric IKDC score, Single Assessment Numeric Evaluation (SANE) score, and peak torque asymmetry of knee flexion and extension using Spearman correlations. Discriminant validity testing was performed against age (Spearman correlation), body mass index (Spearman correlation), and sex (Mann-Whitney U test). Reliability testing was performed by calculating Cronbach’s alpha. Floor and ceiling effects were assessed by calculating the number of minimum and maximum scores in the cohort. Results: A total of 51 patients were included in the final analysis. The mean age at surgery was 15.2 ± 2.2 years, and 51.0% were female. The 6- and 12-item ACL-RSI scales demonstrated a strong significant positive correlation with IKDC/Pediatric IKDC scores ( R = 0.723 and 0.717, respectively; P < .001) and moderate significant positive correlation with Single Assessment Numeric Evaluation scores ( R = 0.516 and 0.502, respectively; P < .001) Age at surgery, body mass index, and sex were not correlated with either ACL-RSI scale. Cronbach’s alpha values of the 12- and 6-item ACL-RSI scales in this population were 0.959 and 0.897, respectively. For both the 12- and the 6-item ACL-RSI scales, no floor or ceiling effects were found as the minimum score (0) was not observed in either version, and the maximum score (100) was only observed twice (3.9%) in both versions. Conclusion: The ACL-RSI scale is valid to use with pediatric and adolescent patients. The 6-item scale may be a better choice because it has fewer redundancies and minimizes the risk of questionnaire fatigue.

“…A cultural and linguistic adaptation of the Pedi-IKDC questionnaire for Lithuanian paediatric patients with knee disorders was created and its psychometric properties were evaluated. So far, there are few validated PROMs in orthopaedic and even knee-addressed conditions in children [4,20,25,26,[43][44][45]. The fundamental issue is that many studies do not use appropriate PROMs for children or use them without validation [32,46].…”

“…In addition, van der Velden et al performed a study on the Pedi-IKDC and KOOS-Child scores and determined that Pedi-IKDC had superior psychometric properties, making it a better instrument for evaluating knee function in children [31]. However, separate items of Pedi-IKDC have been criticised [43]. Another significant issue presently is the validation technique, which is not sufficiently standardised and is currently being debated [2,6,33,47].…”

Introduction: The selection of an appropriate PROM is a crucial aspect in assessing outcomes. Questionnaires that have not been designed or validated for a paediatric population are routinely used. Using a questionnaire requires translation, cultural adaptation, and testing the psychometric properties of the translated questionnaire. There is no applicable questionnaire in our country for children with knee-specific conditions in sports orthopaedics. Therefore, this study aims to translate, culturally adapt, and assess the psychometric properties of the Paediatric IKDC (Pedi-IKDC) questionnaire within the Lithuanian paediatric population. Methods: The translation was conducted in accordance with international standards. Patients aged 11–17 years with various knee disorders participated in three surveys and completed the Pedi-IKDC, Lysholm, and PedsQL questionnaires. Interviews with patients following the translation process, in addition to floor and ceiling effects, were used to assess content validity. Cronbach alpha (α) statistics and the intraclass correlation coefficient (ICC) were applied to measure internal consistency and reproducibility, respectively. The standard error of measurement (SEM) and smallest detectable change (SDC) were calculated to assess reliability. Pearson correlations were calculated between Pedi-IKDC and Lysholm PedsQL scores to determine criteria validity. The effect size (ES) and standardised response mean (SRM) were calculated to assess the responsiveness to change. Results: Cronbach’s alpha (α) was 0.91 for the total score, 0.75 for symptoms, and 0.92 for the sport/function component. The ICC for overall scores was 0.98, with each question ranging from 0.87 to 0.98. The SEM was 2.97, and the SDC was 8.23. Lysholm and PedsQL physical functioning domain scores had moderate correlations (0.8 > r > 0.5), and the overall PedsQL score had a weak correlation (0.5 > r > 0.2) to the Pedi-IKDC score. The floor and ceiling effects were 3.3% and 1.6%, respectively. The SRM was 1.72 and the ES was 1.98. Conclusions: The Lithuanian Pedi-IKDC version is an appropriate evaluation instrument for assessing outcomes in children with knee disorders. All of the psychometric features produced acceptable results.

“…To the date, Pedi-IKDC is the most studied and should be preferred over other PROMs [11]. However, separate items of Pedi-IKDC have been criticized [24]. For the time being, the Pedi-IKDC is available in English [8] original), Danish [13], Dutch [4], and in Italian language [15].…”

Background/Purpose: The usage of children adapted PROMs is encouraged. This study is designed to translate and adapt the Pedi-IKDC for Lithuanian children with knee disorders and evaluate the psychometric properties of the new Pedi-IKDC version. Methods: The translation process was performed under international guidelines. Patients aged 11-17 years with various knee disorders participated at three surveys and completed the Pedi-IKDC, Lysholm and PedsQL questionnaires. The internal consistency and reproducibility were determined by Cronbach alpha (a) statistics and intraclass correlation coefficient (ICC) respectively. For evaluation of reliability the standard error of measurement (SEM) and the smallest detectable change (SDC) were estimated. Regarding criterion validity, the Pearson correlations were assessed between Pedi-IKDC and Lysholm, PedsQL scores. The responsiveness to change was checked by calculating the effect size (ES) and standardized response mean (SRM). The floor and ceiling effects were verified for content validity. Results: The Cronbach alpha (a) was 0.91 for overall score, 0.75 for symptoms and 0.92 for sport/function component of the score. The ICC for overall scores was 0.98 and from 0.87 to 0.98 for separate questions. SEM was 2.97 and SDC – 8.23. Moderate correlations (0.8> r > 0.5) were found to Lysholm and PedsQL physical functioning domain score, weak (0.5>r > 0.2) - to overall PedsQL score. Floor and ceiling effects were - 3,3%, and 1,6% respectively. The ES was 1,98 and SRM- 1,72. Conclusions: The Lithuanian Pedi-IKDC version is suitable measurement tool to assess outcomes within paediatric population with different knee disorders. All the psychometric properties demonstrated acceptable results.
