“…The results from the present study showed a very high Cronbach’s alpha for internal consistency for the FFI-RSN which is in line with results from other studies [ 12 , 16 ]. This result implies that the multiple items in FFI-RSN have a high interrelatedness.…”

“…The FFI was revised into a long (FFI-RL) and a short version (FFI-RS) by developing a theoretical model of foot function based on the World Health Organization International Classification of Function (ICF) [ 12 ]. As far as we are aware, the original FFI has been translated into seven languages [ 13 ], whereas the FFI-RL has only been translated into Brazilian Portuguese [ 14 ] and Turkish [ 15 ] and the FFI-RS into Polish [ 16 ]. The reliability, content and construct validity, effect size and the smallest detectable change (SDC) have been reported for the FFI-RL [ 13 , 17 , 18 ].…”

“…The reliability, content and construct validity, effect size and the smallest detectable change (SDC) have been reported for the FFI-RL [ 13 , 17 , 18 ]. The FFI-RS has similar psychometric properties to the FFI-RL for internal consistency [ 12 ] and good test-retest reliability [ 16 ]. The responsiveness of the FFI-RS has only been reported on each subscale [ 19 ], and we are unable to find studies that report on the SDC, MIC or responsiveness of the total score of the FFI-RS [ 20 ].…”

Background Foot disorders affect up to one quarter of the adult population. Plantar fasciopathy is a common cause of foot pain associated with decreased activity level and quality of life. Patient-reported outcome measures are important in assessing the burden of a condition as well as in research on the effects of interventions. The Foot Function Index revised short form (FFI-RS) is a region specific questionnaire frequently used in research. This study aimed to cross-culturally adapt the FFI-RS into Norwegian and to test its psychometric properties. Methods The FFI-RS was translated into Norwegian (FFI-RSN) following international guidelines. 139 patients with foot disorders (88% with plantar fasciopathy) were included at baseline to measure internal consistency, explorative factor analysis, construct validity and floor and ceiling effects. 54 patients were included after 1 week for test-retest reliability and smallest detectable change analyses. 100 patients were included for responsiveness and minimal important change at 3 months. Results Cronbach’s alpha for internal consistency was 0.97 and factor analysis supported the use of the total score of the FFI-RSN. Two out of three predefined hypotheses were confirmed by assessing the construct validity with Spearman’s correlation coefficient. Quadratic weighted Kappa for test-retest reliability showed 0.91 (95% CI 0.86–0.96) and the smallest detectable change was 6.5%. The minimal important change was 8.4% and the area under the receiver operating characteristic curve for responsiveness was 0.78 (95% CI 0.69–0.87). We found no floor or ceiling effects on the total score of the FFI-RSN. Conclusions The present study showed excellent reliability of the FFI-RSN and supports the use of the total score of the questionnaire. Furthermore, we found the FFI-RSN to have acceptable responsiveness in relation to change in general health. Smallest detectable change, minimal important change and responsiveness were presented as novel results of the total score of the FFI-RS. FFI-RSN can be used to evaluate global foot health in clinical or research settings with Norwegian patients suffering from plantar fasciopathy. Trial registration Clinical Trials.gov NCT04207164. Initial release 01.11.19.

“…The Revised Foot Function Index (FFI-R) is a validated self-report measure that assesses foot-function related to health (Budiman-Mak et al, 2006;Hung et al, 2012). Studies have shown that the FFI-R is valid and reliable when translated and cross-culturally adapted (Rutkowski et al, 2017;Stéfani et al, 2017;Yagci et al, 2019). The FFI-R was translated to Malagasy and cross-culturally adapted for our participants.…”

Objectives: Foot and ankle dysfunction in barefoot/minimally shod populations remains understudied. Although factors affecting musculoskeletal pain in Western populations are well-studied, little is known about how types of work, gender, and body shape influence bone and joint health in non-Western and minimally shod communities. This study examines the effect of human variation on locomotor disability in an agrarian community in Madagascar.Materials and methods: Foot measurements were collected along with height, weight, age, and self-report data on daily activity and foot and ankle pain from 41 male and 48 female adults. A short form revised foot function index (FFI-R), that measures functional disability related to foot pain, was calculated. Raw and normalized foot measurements were compared by gender and used in a multiple linear regression model to determine predictors of FFI-R.Results: Compared to men, women reported higher FFI-R scores (p = 0.014), spent more time on their feet (p = 0.019), and had higher BMIs (p = 0.0001). For their weight, women had significantly smaller and narrower feet than men. Bimalleolar breadth (p = 0.0005) and foot length (p = 0.0223) standardized by height, time spent on feet (p = 0.0102), ankle circumference standardized by weight (p = 0.0316), and age (p = 0.0090) were significant predictors of FFI-R score.Discussion: Our findings suggest that human variation in anatomical and behavioral patterns serve as significant explanations for increased foot and ankle pain in women in this non-Western rural population. Foot and ankle pain were prevalent at similar levels to those in industrialized populations, indicating that research should continue to examine its effect on similar barefoot/minimally shod communities.
