8-Item Sports Subscale

Original Editor - Kim Jackson Top Contributors - Kim Jackson

Introduction

The 8-items Sports Measure is part of the Foot and Ankle Ability Measure (FAAM). The FAAM is a self-report outcome instrument developed to assess physical function for individuals with foot and ankle related impairments. This self-report outcome instrument is available in English, German, French and Persian. The Foot and Ankle Ability Measure is a 29-item questionnaire divided into two subscales: the Foot and Ankle Ability Measure, 21-item Activities of Daily Living Subscale and the Foot and Ankle Ability Measure, 8-item Sports Subscale. The Sports subscale assesses more difficult tasks that are essential to sport, it is a population-specific subscale designed for athletes[1][2][3].

For the most valid results it is suggested that scores for the FAAM ADL and Sports subscales be generated only when subjects completed 90% or more of the items (19 of 21 for the ADL and 7 of 8 for the Sports subscales respectively)[1]

Scoring the FAAM

  • The response to each item on the Sports subscale is scored from 4 to 0, with 4 being “no difficulty” and 0 being “unable to do”.
  • If an activity is limited by something other than their foot or ankle is scored as N/A - N/A responses are not counted.
  • The scores on each item are added together to get the item score total.
  • The number of items with a response is multiplied by 4 to get the highest potential score.
  • If the subject answers all 8 items the highest potential score is 32. If one item is not answered the highest potential score is 28, if two are not answered the highest potential score is 24, etc.
  • The item score total is divided by the highest potential score. This value is multiplied by 100 to get a percentage.
  • A higher score represents a higher level of physical function.
