Acute lateral ankle sprains are common amongst athletes, and screening is essential in preventing these long-term sequelae. Self-reported questionnaires, such as the Cumberland Ankle Instability Tool (CAIT), may help identify individuals with chronic ankle instability. To date, a Cantonese-Chinese version of the CAIT does not exist. A cross-cultural adaptation and validation of the CAIT were carried out: 46 individuals who were native in Cantonese completed the Cantonese-Chinese version of the CAIT and Chinese Foot and Ankle Outcome Score. For the test-retest analysis, the intraclass correlation coefficient was 0.874. Internal consistency showed a Cronbach’s ɑ value of 0.726. Construct validity against the FAOS was fair but statistically significant with a Spearman’s correlation coefficient of 0.353, 0.460, 0.303, 0.369 and 0.493 for the categories of symptoms, pain, daily function, sports function, and quality of life, respectively. A cutoff score of 20.5 was determined to differentiate healthy individuals from those with chronic ankle instability for this study population. The original English CAIT was successfully translated, cross-culturally adapted and validated into Cantonese-Chinese. •CAIT is a patient-reported outcome tool for chronic ankle instability.•CAIT is not available in Cantonese, a Chinese dialect spoken by 62 million people.•CAIT-HK is a validated and reliable adaptation of CAIT in the Cantonese language.•CAIT-HK cut-off score of 20.5 indicates ankle instability.
