OBJECTIVE: To validate the function score for adult Tibetans with Kashin-Beck disease (FSAT- KBD) measuring daily life and work functional status of KBD patients.
METHODS: From September to October 2010, 352 adult KBD patients in Rangtang County of Aba Tibetan autonomous region were invited to complete FSAT-KBD. The internal consistency of FSAT-KBD was assessed using Cronbach's alpha coefficients. Principal component analysis with varimax rotation was performed to explore factor structure of the instrument, with item-domain correlations being examined using Spearman's rank correlation tests. Discriminant validity of the FSAT-KBD was assessed by comparing scores of the respondents with different ages and different functional status. Convergent validity of the FSAT-KBD was assessed through a comparison with the medical outcomes study short form health survey (SF-12) and visual analogue scale (VAS).
RESULTS: 338 KBD patients (a response rate of 96.0%) completed the questionnaire in an average of (3.2 +/- 1.6) min. The instrument achieved a Cronbach's alpha of 0.945, with item-to-domain correlations exceeding 0.0. Two latent factors were extracted, which explained 72.8% of the total variance. The factor structure fitted well with our conceptual hypothesis. Respondents with different age, duration of suffering and number of affected joints had different FSAT-KBD scores. The FSAT-KBD results were correlated with those of SF-12 and VAS.
CONCLUSION: FSAT-KBD is a reliable and valid instrument for measuring daily functional status of adult KBD patients in Aba Tibetan autonomous area in China.
