*Scores > 0.9 may indicate redundancy

Predictive validity:

Multiple sclerosis: (Vliet et al., 2013)

• Good predictive validity was established through its ability to discriminate between multiple fallers and non-multiple fallers assessed during a 12-month follow-up period, suggesting that the FES-I is likely to have an acceptable sensitivity to change in people with MS.

Convergent Validity

Multiple sclerosis: (Vliet et al., 2013)

Discriminant validity

Multiple sclerosis: (Vliet et al., 2013, n = 169, mean age = 50.6 (10.9) years )

• Poor correlations between FES-I and the duration of the disease (P = 0.138) is indicative of good discriminant validity, suggesting that high FES-I scores are not merely a reflection of disease duration.

Elderly with hip fracture: (Visschedijk et al., 2015, Group 1, n = 100, mean age = 83.1 (8.3) years, Group 2, n = 23, mean age  = 83.2 (7.2) years)

Elderly with hip fracture:

• Excellent internal consistency (Cronbach¡¯s alpha = 0.94*), 3th or 4^th week after admission to SNF (Visschedijk et al., 2015)

*Scores > 0.9 may indicate redundancy

• The FES-I was developed through a series of meetings between members of the Prevention of Falls Network Europe (ProFaNE), an EC funded collaboration coordinating research into fall prevention.
• Members examined the existing items of the FES to identify any potential difficulties they might pose either for accurate translation or for applicability to their cultural context.
• The wording of items that posed potential problems was then revised through discussion. For example, the item ¡®Reaching into cabinets or closets¡¯ appeared ambiguous because of cross-cultural differences in the use of storage space and the terms employed to describe it; consequently, the activity this item assessed was standardised as ¡®Reaching up or bending down¡¯ (Yardley, Beyer, Hauer, Kempen, Piot-Zieglers & Todd, 2005).

• Not assessed statistically, however, the authors selected additional items with cross-cultural face validity to assess more difficult and social activities based on the literature and the professional experience of members.
• The resulting questionnaire comprised 16 items, including the 10 original items from the FES (with some rewording where necessary) and six new items assessing walking on slippery, uneven or sloping surfaces, and visiting friends or relatives, going to a social event or going to a place with crowds.
• The authors employed the revised FES instructions and response categories that assess level of concern about falling when carrying out each activity on a four point scale (1=not at all concerned, 4=very concerned) (Yardley et al., 2005).
