| Objective：To explore the applicability of SF-36 Scale on diabetic foot patients, and to find out the evaluation standard of QOL of diabetic foot patients. Methods：239 patients of department of burn & wound repair were treated and then surveyed with SF-36 Scale. The feasibility, reliability, validity, ceiling effect and floor effect, and responsibility were analyzed. Results：1. The feasibility analysis: Completion time for the scale was 16.9±3.2 min, and finishing rate was 100%. 2. The reliability analysis: All the split-half reliability coefficients and the Cronbach's α were above 0.8. All the internal consistency coefficients were above 0.6. 3. The validity analysis: Two principal components were extracted by factor analysis，which accounted for 69.03% of total variance. After the maximum variance rotation, two common factors were generated, which was almost the same as the theory structure assumption of scale. All the Pearson coefficients were above 0.6. 4.Ceiling effect and floor effect: There was remarkable floor effect on RP(28.76%) and PF(33.69%). 5.The responsibility analysis: After treatment the score of other degree was improved significantly（P＜0.05）. Conclusion：SF-36 Scale can be preferably applied to the evaluation of QOL among diabetic foot patients, but individual items need to be further perfected. |
