BACKGROUND: Many existing scoring systems assess ankle function, but there is no evidence that any of them has been validated in a group of patients with a higher demand on their ankle function. Problems include ceiling effects, not being able to detect change or they do not contain a sports-subscale. The aim of this study was to create a validated self-administered scoring system for ankle injuries in the higher performing athlete.METHODS: First, 26 patients were interviewed to solicit opinions needed to create the final score, which is modified from the Foot and Ankle Outcome Score (FAOS). Second, SAFAS was validated in a group of 25 athletes with and 14 athletes without ankle injury. It is a self-administered region specific sports foot and ankle score that contains four subscales assessing the levels of symptoms, pain, daily living and sports.RESULTS: The Spearman correlation coefficients between SAFAS and the Foot and Ankle Ability Measure (FAAM) ranged from 0.78 to 0.88. Content validity is established by key informant interviews, expert opinions and a high satisfaction rate of 75%. Cronbach's alpha indicated good internal consistency of each subscale ranging from 0.77 to 0.92.CONCLUSION: SAFAS has shown good evidence for being a valid instrudent for assessing sports-related ankle injuries in high-performing athletes.
