Brief summary

There have previously been no validated a specific foot and ankle patient-reported outcome measures in Turkish. The Visual Analogue Scale Foot and Ankle (VAS-FA) will translated and adapted into Turkish language. Thereafter, 200 patients who had foot and ankle disorders or surgery will complete VAS-FA questionnaire set on two separate occasions. Analyses included testing of floor-ceiling effect, internal consistency, reproducibility, and validity.

Design outcomes

Primary

MeasureTime frameDescription
VAS-FA Turkish version1 weekThe VAS-FA contains 20 questions for the patient with five possible answers. For each question a VAS-value from 0 to 100 points is possible. The total value for the entire score (all 20 questions answered) is therefore 0-2000 points. This total value is then divided by 20, resulting in a possible total score ranging from 0 to 100 points.

Secondary

MeasureTime frameDescription
Foot Function Index (FFI)1 weekIt is a self-administered index consisting of 23 items divided into three subscales. To obtain a subscale score, the item scores for subscales are totaled and then divided by the maximum total possible for all of the subscale items that the patient indicates is applicable. Therefore, subscale scores range from 0 to 100, with higher scores indicating greater impairment. A total foot function score is derived by calculating the average of the three subscale scores.
Short Form-36 (SF-36)1 weekCompletion of the 36 items yielded an 8-subscale profile of patient functional health and well being, as well as empirically derived physical and mental health component summary (PCS and MCS) measures. The subscales are scored as percentages and the summary measures are scaled to provide a score out of 50%.
