Validation and cultural adaptation of the Russian version of the Pedi-IKDC questionnaire

Abstract

BACKGROUND: Questionnaires are standard tools used for examination of patients. Obtained data provide information about knee function disturbance and level of the quality of life. Young patients with various knee injuries also needed examination questionnaires. In worldwide practice, the Pediatric International Knee Documentation Committee (Pedi-IKDC) is more often used by doctors. However, if the doctor wants to use foreign questionnaire in his/her practice, the questionnaire should be validated and culturally adaptable.
 AIM: This study aimed to enable the validation and cultural adaptation of the Russian version of the Pedi-IKDC questionnaire based on the English version for children and adolescent.
 MATERIALS AND METHODS: This questionnaire was translated from English by professional medical translator and by orthopedic surgeon. The Lysholm questionnaire was also used to control the adequacy of Pedi-IKDC results. Statistical analysis was performed to process data.
 RESULTS: Cronbachs alpha was 0.902, which means that questions have high level of consistency. The high correlation of results between the Lysholm and Pedi-IKDC questionnaire also proves the adequateness and objectiveness of the results.
 CONCLUSIONS: The proposed Russian version of the Pedi-IKDС questionnaire gives effective, objective, and adequate results. It is a good tool for knee assessment in children.

Validation of the Moroccan Arabic Version of the Pediatric International Knee Documentation Committee Score (Pedi-IKDC) Questionnaire for Children With Knee Disorders

“…The Moroccan version of Pedi-IKDC demonstrated a good correlation between the different items in the form (Cronbach alpha= 0.7). Other validation studies [ 14 , 16 , 18 , 20 , 21 ] also showed good internal validity.…”

High recall bias in retrospective assessment of the pediatric International Knee Documentation Committee Questionnaire (Pedi-IKDC) in children with knee pathologies

“…It ranges from 0 to 100, with higher scores indicating less pain and better function. Currently, it has been translated in English [17], Danish [15], Dutch [42], Italian [24], and Russian [13]. The validation studies were conducted in pediatric populations affected by a broad spectrum of knee pathologies.…”

“…They are patient‐reported questionnaires administered to patients and allow the evaluation of specific pathologies or body regions [11]. It is recommended that specifically designed PROMs should be used in children and adolescent populations [7, 14], and the pediatric version of the International Knee Documentation Committee Questionnaire (Pedi‐IKDC) is currently one of the most widely validated and reliable scores [13, 15, 17, 24, 42]. There are two main approaches for administering PROMs [1, 18].…”
