The Italian cross-cultural adaptations of the paediatric International Knee Documentation Committee Score and the Hospital for Special Surgery Paediatric Functional Activity Brief Scale are reliable instruments in paediatric population

Abstract

Purpose The aim of the present study was to translate, cross‐culturally adapt, and assess the psychometric properties of the Pedi‐IKDC and Pedi‐FABS scores in the Italian paediatric population with various knee pathologies. Methods In accordance with the Paediatric Anterior Cruciate Ligament Monitoring Initiative (PAMI) research protocol, the original English versions of the questionnaires were translated into Italian. All patients aged 8–16 and scheduled for knee surgery were considered eligible in the study. An open‐source platform was implemented to collect responses to the surveys which included general patient information, the questionnaires Pedi‐IKDC, and Pedi‐FABS. Two surveys were sent under stable clinical conditions before surgery (Q1 and Q2); a third survey was sent 3–4 months after surgery (Q3). The following properties were calculated: reliability, internal consistency, criterion validity, responsiveness, and floor/ceiling effects. Results Eighty‐nine patients completed Q1, 81 patients completed Q2, and 49 patients completed Q3. Both questionnaires demonstrated acceptable properties. Pedi‐IKDC: standard error of measurement (SEM) = 4.4, smallest detectable change (SDC) = 12.3, interclass correlation coefficient (ICC) = 0.96, Cronbach alpha (α) = 0.92, moderate‐to‐low correlation to Pedi‐FABS, effect size (ES) = 0.79, standardized response mean (SRM) = 0.86, floor = 0%, ceiling = 22%. Pedi‐FABS: SEM = 2.1, SDC = 5.8, ICC = 0.94, Cronback alpha (α) = 0.93, moderate‐to‐low correlation to Pedi‐IKDK, ES = 0.60, SRM = 0.51, floor = 19%, ceiling = 0%. Conclusions The Italian version of Pedi‐IKDC and Pedi‐FABS is valuable tools for patient assessment, by demonstrating good psychometric properties. In clinical setting, these questionnaires can be used to properly evaluate outcomes in Italian pediatric patients with knee pathologies. Level of evidence II.

Good Subjective Outcomes, Stable Knee and High Return to Sport after Tibial Eminence Avulsion Fracture in Children

“…Following the Paediatric ACL Monitoring Initiative (PAMI), we recently validated the Italian version of the pedi-IKDC and pedi-FABS scores. Both these scores were specifically designed for children and adolescents, having demonstrated good to excellent reliability and responsiveness [ 14 , 15 , 17 ].…”

“…Patients were contacted and the Italian version [ 14 ] of the pediatric International Knee Documentation Committee score (Pedi-IKDC) (score of 0 to 100 with higher score equivalent to less pain and better function, and a minimally clinical important difference of 12 points) [ 15 , 16 ], and the Hospital for Special Surgery pediatric Functional Activity Brief Scale (Pedi-FABS) [ 17 ] (score 0 to 30 with higher score meaning better performance) were administered. Return to sport and further surgeries were inquired as well.…”

Translation and transcultural validation of the Dutch Hospital for Special Surgery Paediatric Activity Brief Scale (HSS Pedi-FABS)

“…[8] The questionnaire consists of 6 Likert-based items regarding frequency of activities, one item on the level of sports and one item on supervision. [8,13] Scores range from 0 to 30, with a higher score indicating more physical activity. [8,13] To date, the PAQ-C and PAQ-A are the only validated Dutch questionnaires to assess physical activity in children and adolescents.…”

“…[12] This European initiative launched by the European Society for Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) aims to create a pan-European system to collect and analyse data to provide stronger scienti c evidence in paediatric ACL injury treatment. [12,13,14] Yet, the HSS Pedi-FABS is currently only available in English and Italian. [8,13] Therefore, it is crucial to transculturally validate the Dutch HSS Pedi-FABS.…”

“…[12,13,14] Yet, the HSS Pedi-FABS is currently only available in English and Italian. [8,13] Therefore, it is crucial to transculturally validate the Dutch HSS Pedi-FABS. It is hypothesized that the Dutch HSS Pedi-FABS has adequate psychometric properties in a healthy paediatric and adolescent population, comparable to the psychometric properties of the original HSS Pedi-FABS.…”
