Estimation on the reliability and validity of the fatigue self-assessment scale / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the reliability and validity of the Fatigue Self-assessment Scale (FSAS).</p><p><b>METHODS</b>The scale was applied among the participants assigned to 4 groups, the differences in types, degrees and characteristics of fatigue of them were compared, and the reliability and constitutional validity of ESAS were assessed by internal consistency analysis, exploratory factor analysis and confirmatory factor analysis using the statistical software of SPSS and LISREL.</p><p><b>RESULTS</b>Statistical differences of types, degrees and characteristics of fatigue presented in the participants of the 4 groups. The Cronbach's alpha of various factors in the scale were 0.772-0.908; the indexes for the section of assessing type, and degree of fatigue were RMSEA=0.065, NNFI=0.95, CFI=0.96; and those for the section of assessing characteristics of fatigue were RMSEA=0.10, NNFI=0.93, CFI=0.96.</p><p><b>CONCLUSION</b>The FSAS has good differentiability, reliability and constitutional validity for assessing the type, degree and characteristics of fatigue in various populations. In order to explore the relationship of TCM syndrome patterns with the type, degree and characteristics of fatigue, its future application for evaluation of fatigue and intervention effect of anti-fatigue should be combined with TCM syndrome differentiation.</p>
