Abstract:
Introduction: This study was designed to produce a
validated and reliable Malay version of the Identification of
Functional Ankle Instability (IdFAI-M) questionnaire.
Materials and method: The cross-cultural adaptation was
conducted based on standard guidelines to produce the
Malay version of the Identification of Functional Ankle
Instability (IdFAI-M) questionnaire. The reliability and
validity testing were then performed among one hundred and
twenty-three physically active University of Malaya
students. Among them, twenty-two students also participated
in the second return of the questionnaire over a two-week
interval, which was then evaluated for test-retest reliability
testing.
Results: The content validity for item-level (I-CVI) and
Kappa values for all items were more than 0.7, respectively
and the all scales-level (S-CVI) values were 0.983
(consistency), 0.967 (representativeness), 1.00 (relevance)
and 0.983 (clarity). The questionnaire also demonstrated
excellent reliability with an intraclass correlation coefficient
(ICC2.1) above 0.850 for all items. It was observed that outer
loading of most items were more than the minimum
acceptable value (0.7). Fornell-Larcker criterion demonstrate
all values for each reflective construct was larger than the
correlations with other constructs, indicating discriminant.
The cross-loading values of each item has shown a weak
correlation with all other constructs, except for the one to
which it was theoretically associated.
Conclusions: The Malay version of the IdFAI (IdFAI-M) is
a reliable and valid instrument that can be readily utilised to
subjectively assess ankle instability.
