Cross-cultural adaptation and validation of the Arabic version of oxford ankle foot questionnaire for children

Abstract

Purpose

The purpose of this study was to translate and cross-culturally adapt the original English version of the Oxford Ankle Foot Questionnaire (OxAFQ-c) into the Arabic language, and to evaluate its psychometric properties among Arabic speaking children aged from 5 to 16 years in Saudi Arabia.

Materials and methods

An Arabic OxAFQ-c for children was developed according to established guidelines (ISPOR). The Arabic OxAFQ-c version was completed by eighty-seven patients with foot and ankle problems and their caregivers. Construct validity of the Arabic OxAFQ-c was also examined.

Results

The reliability analysis of OxAFQ-Ar exhibited good internal consistency in both children's and parent's versions for all domains (α = 0.80–0.89) and excellent test-retest reliability in both versions for all domains. (ICC = 0.87–0.94). A moderate correlation between the OxAFQ-Ar and PedsQL 4.0 was observed indicating moderate construct validity.

Conclusions

The OxAFQ-c was successfully translated and cross-cultural adapted into the Arabic language. The OxAFQ-Ar is a valid, reliable and useful quality of life questionnaire for evaluating children’s ankle foot problems.

IMPLICATION OF REHABILITATION OF OxAFQ-c ARABIC VERSION

• The Arabic version of the OxAFQ-c is an acceptable, clear and comprehensible outcome measure.

• The Arabic version of the OxAFQ-c demonstrated evidence supporting its internal consistency, test-retest reliability and construct validity as a measure to evaluate foot and ankle pathologies in patients aged 5–16 years.

• The Arabic OxAFQ-c has very good internal consistency, test-retest reliability, and acceptable measurement error with no floor and ceiling effects.

• The Arabic version of the OxAFQ-c can be used in daily clinical practice and in research studies to assess children aged from 5 to 16 years in Arabic speakers with ankle-foot conditions.
