Table 2 Discriminant capacity of the original and short FES-I

From: Psychometric properties of the original and short versions of the Falls Efficacy Scale-International (FES-I) in people with Parkinson’s disease

  Fear of falling
  No Yes p
Original FES-I 19 (17–24) 36 (26–47) <0.001
Short FES-I 8 (7–10) 26 (12–20) <0.001
  Activity avoidance
  No Yes p
Original FES-I 20 (17–25) 37 (26–47) <0.001
Short FES-I 8 (7–11) 16 (12–20) <0.001
  Falls past six months
  No Yes p
Original FES-I 22 (18–30) 38 (27–48) <0.001
Short FES-I 9 (7–13) 17 (12–20) <0.001
  Near falls past six months
  No Yes p
Original FES-I 22 (17–25) 32 (24–46) <0.001
Short FES-I 9 (7–12) 14 (10–20) <0.001
  Self-rated Parkinson severity
  Mild Moderate Severe p
Original FES-I 20 (17–23) 29 (20–41) 45 (30–54) <0.001*
Short FES-I 8 (7–9) 12 (9–17) 20 (13–23) <0.001*
  1. Data are presented as median (first-third quartile)
  2. P-values are based on Mann-Whitney U-tests, except the p-values for Self-rated Parkinson severity, which are based on Kruskal-Wallis test
  3. FES-I Falls Efficacy Scale-International. Possible scoring ranges: Original 16–64, Short 7–28; higher = worse
  4. *All subsequent unpaired comparisons showed statistical significant differences (Bonferroni correction criterion of p < 0.016), except between persons with Moderate and Severe Parkinson severity for Short FES-I (p = 0.017)
