| 目的 探讨骨质疏松症自我效能量表在上海社区居民中的信度和效度。方法 应用骨质疏松症自我效能量表对2003名社区居民进行测查，分层随机抽样20例居民在初次测评1月后再次进行量表的评定。采用结构效度、内容效度及效标效度检测量表的效度。采用内部一致性信度克隆巴赫α系数、重测信度及分半信度三个指标检测量表的信度。结果 探索性因子分析有两个公因子被提取, 即运动自我效能和摄钙自我效能, 累计方差百分比为81.9%，验证性因子分析模型与原假设一致，?2/df=3.835，CFI＝0.977，GFI=0.941。内容效度各条目与分维度具有显著相关性。自我效能与预防行为间也存在联系；骨质疏松自我效能量表内部一致性信度系数为0.958，重测信度相关系数为0.931，分半信度系数为0.980。结论 骨质疏松自我效能量表应用于上海社区居民具有良好的信度和效度。 |

| Objective To explore the reliability and validity of the osteoporosis self‐efficacy scale among residents in shanghai communities. Methods A total of 2003 community residents were tested with osteoporosis self‐efficacy scale. Among them, 20 cases were stratified randomly and retested 1 month later. The validity of the scale was evaluated by structural validity, content validity, and criterion validity. The reliability of the scale was tested by Cronbach's alpha coefficient, retest reliability, and split-half reliability. Results The exploratory factor analysis showed that the variance contribution rate of the two factors, exercise self-efficacy and calcium self-efficacy, was 61.688%. Results of confirmatory factor analysis indicated that the model was consistent with the theoretical assumption, and the fitness indexes were ?2/df=3.835, CFI=0.977, GFI=0.941. Each item had a significant correlation with the sub-dimension. Osteoporosis self-efficacy was shown to have association with preventive behavior. Cronbach's alpha coefficient of the scale was 0.958. The test-retest correlation coefficient was 0.931. The split-half reliability coefficient was 0.980. Conclusion Osteoporosis self‐efficacy scale has good reliability and validity among community residents in Shanghai. |
