Background:

The American Orthopedic Foot and Ankle Society score (AOFAS)

and the “Self-reported Foot and Ankle Score” (SEFAS) are patient-reported

outcome measures used to assess ankle pain and functional outcome. They have

not earlyer been translated into Danish.

Purpose / Aim of Study:

The aim of this study was to cross-culturally translate

and adapt AOFAS-Da and SEFAS-Da into Danish and perform reliability testing.

Materials and Methods:

The two questionnaires were cross-culturally trans-

lated and adapted into Danish by process guidelines including translation, syn-

thesis, back translation, expert committee review, and pretesting. Face validity

was accessed in 10 patients with ankle and foot disorders and 5 people with

a medical education. 60 patients completed the two questionnaires 6 weeks

post-operatively (test, T1) and again at mean 9 days after (retest, T2). Pearson

´s correlation was used to access test-retest and internal consistency was ac-

cessed with Cronbach´s Alpha. Floor and ceiling effects were considered pres-

ent if > 15% of the patients achieved the worst score/floor effect or the best

score/ceiling effect.

Findings / Results:

Pearson´s correlation for SEFAS-Da was 0.93 (95%CI:

0.84-1.01) (n=60) and for AOFAS-Da, 0.92 (95%CI:0.83-1.02) while

Cronbach´s alpha was 0.87 and 0.88 for SEFAS-Da and AOFAS-Da, respec-

tively. No floor or ceiling effect was observed (T1: 0/48 for SEFAS and 1/60 for

AOFAS. T2: 0/48 for SEFAS-Da and 1/60 for AOFAS-Da).

Conclusions:

The Danish versions of AOFAS-Da and SEFAS-Da, showed strong

reliability with internal consistency and test-retest reproducibility in patients

with ankle related fractures.
