Validation of the translated Oxford ankle foot questionnaire in 82 Danish children aged between five and 16 years

Abstract

We present the validation of a translation into Danish of the Oxford ankle foot questionnaire (OxAFQ). We followed the Isis Pros guidelines for translation and pilot-tested the questionnaire on ten children and their parents. Following modifications we tested the validity of the final questionnaire on 82 children (36 boys and 45 girls) with a mean age of 11.7 years (5.5 to 16.0) and their parents. We tested the reliability (repeatability (test-retest), child-parent agreement, internal consistency), feasibility (response rate, time to completion, floor and ceiling effects) and construct validity. The generic child health questionnaire was used for comparison. We found good internal consistency for the physical and the school and play domains, but lower internal consistency for the emotional domain. Overall, good repeatability was found within children and parents as well as agreement between children and parents. The OxAFQ was fast and easy to complete, but we observed a tendency towards ceiling effects in the school and play and emotional domains. To our knowledge this is the first independent validation of the OxAFQ in any language. We found it valid and feasible for use in the clinic to assess the impact on children's lives of foot and/or ankle disorders. It is a valuable research tool.

Translation and Test–Retest of the Spanish Podiatry Health Questionnaire (PHQ-S)

“…For example, we think the foot health-related QoL context in Spain may differ from the UK, since nowadays podiatry is not included in the public health service. Thirdly, different age distributions (such as children) were not included in this Spanish version validation, while different scales were considered in this age range (such as in the Oxford Ankle Foot Questionnaire) which was validated in children from five to 16 years old [ 26 ]. Thus, we can only recommend this questionnaire for the studied age distribution, while future studies should include all age ranges.…”

Transcultural adaptation and validation of Italian Selfcare diabetic foot questionnaire

“… 1 , 2 , 3 As a final point, age arrangement like infant population were not measured on this validate, whereas other tools like the Oxford questionnaire [Ox‐A.F.Q] conversion was corroborated from in childhood, 5 to 16 years old. 47 …”

Cross‐cultural adaptation, translation, and validation of the Spanish Foot and Ankle Outcome Score questionnaire

“…Second, test/retest in this study was completed with an electronical address while the original FAOS and other Spanish validated scales were developed by face‐to‐face interviews with the study subjects 3,4,11,29 . As a final point, age groups, such as infant populations, were not considered in this validation, whereas other tools, such as the Oxford questionnaire (Ox‐AFQ) translation was divided into ages ranging from 5 to 16 years 30 . For future consideration, the main disadvantage was the extension of the FAOS questionnaire, too long, as a difference of another pain scale as Victorian Institute of Sport Assessment (VISA) 31 or Bristol Foot Scale (BFS) 32 shorter than this tool.…”
