aFor the regression analysis, FES(S) scores (range, 0–130) were reversed (0 = better).
bIndependent variables (method: enter with manual backward deletion) were: “Have you been limited in your ability to climb up and down stairs?" (item 5, Walk-12G), “Have you had problems balancing when standing or walking?" (item 6, Walk-12G), “Have you been limited in how far you are able to walk?" (item 11, Walk-12G), turning hesitations (item 6, FOGQsa), and “Has your walking been slow?" (item 12, Walk-12G).
The original five response categories of Walk-12G were recoded before being entered in the model: “not at all,” “a little,” or “moderately-quite a bit-extremely.”
B, regression coefficient; CI, confidence interval; β, standardized regression coefficient.
