The psychometric properties of the Spanish version of the Foot Health Status Questionnaire.
OBJECTIVE
Clinical studies suggest that foot pain may be problematic in one-third of patients in early disease. The Foot Health Status Questionnaire (FHSQ) was developed and validated to evaluate the effectiveness of conservative (orthoses, taping, stretching) and surgery interventions. Despite this fact, there are few validated instruments that measure foot health status in Spanish. Thus, the primary aim of the current study was to translate and evaluate psychometrically a Spanish version of FHSQ.


METHODS
A cross-sectional study was designed in a university community-based podiatric clinic located in south of Spain. All participants (n = 107) recruited consecutively completed a Spanish version of FHSQ and EuroQoL Health Questionnaire 5 dimensions, and 29 participants repeated these same measures 48 h later. Data analysis included test-retest reliability, construct and criterion-related validity and factor analyses.


RESULTS
Construct validity was appropriate with moderate-to-high corrected item-subscale correlations (α = ≥0.739) for all subscales. Test-retest reliability was satisfactory (ICC > 0.932). Factor analysis revealed four dimensions with 86.6% of the common variance explained. The confirmatory factor analysis findings demonstrated that the proposed structure was well supported (comparative fit index = 0.92, standardized root mean square = 0.09). The Spanish EuroQoL 5D score negatively correlated with the FHSQ pain (r = -0.445) and positively with general foot health and function (r = 0.261-0.579), confirming criterion-related validity.


CONCLUSIONS
The clinimetric properties of the Spanish version of FHSQ were satisfactory.
