| 摘要: |
| 目的 引入对肥胖者态度(attitudes toward obese persons, ATOP)量表,并分析其信度和效度。方法 对ATOP量表进行翻译和文化调适,修订形成中文版量表。采用专家小组评价法检验中文版ATOP量表的内容效度。采用整群抽样法抽取407名护理大学生(护生),用中文版ATOP量表进行问卷调查,收集数据,进行结构效度(包括项目分析、探索性因素分析和验证性因素分析)、效标关联效度、内部一致性信度分析；随机选取样本中20名受试者,间隔2周重复测评,用组内相关系数(ICC)分析重测信度。结果 中文版ATOP量表各条目的平均内容效度指数为0.97。经项目分析和探索性因素分析,提取到3个因子(12个条目),可解释变异量的52.45%。验证性因素分析支持量表的三因子结构(χ2=93.75,df=51,χ2/df=1.84,RMSEA=0.06,NNFI=0.91,CFI=0.93,IFI=0.93,GFI=0.93,AGFI=0.89)。量表及其因子与体重心理控制源的外控性因子得分呈正相关。量表及各因子的Cronbach’s α系数为0.59~0.71,重测信度ICC为0.52~0.83。护生的体质指数与其自尊因子得分呈弱负相关；自感超重的护生对自尊因子的评分更低,但对个体差异因子评分更高。结论 中文版ATOP量表具有较好的信度和效度,可用于测评护生对肥胖人群的态度。 |

| Abstract: |
| Objective To evaluate the reliability and validity of a Chinese version of the attitudes toward obese persons (ATOP) scale among college nursing students. Methods A Chinese version of ATOP was obtained by forward translation, synthesis, back translation, and culture adjusting; the content validity was examined by expert committee review. A total of 407 valid questionnaires of Chinese ATOP were completed by a convenient sample of college nursing students. The psychometric properties of ATOP were examined by content validity index (CVI) for content validity, critical ratio (CR) for item analysis, factor analysis for construct validity and Cronbach’s alpha coefficient for internal consistency reliability. Additionally, the intra-class correlation coefficient (ICC) for test-retest reliability was tested in 20 nursing students after a two-week interval. Results The mean CVI of the Chinese version of ATOP was 0.97. The final Chinese version comprised 12 items and reflected 3 dimensions: different personalities, social difficulties and self-esteem, which explained 52.45% of the total variance. Confirmatory factor analysis further supported this three-dimension structure (χ2=93.75, df=51,χ2/df=1.84, RMSEA=0.06, NNFI=0.91, CFI=0.93, IFI=0.93, GFI=0.93, AGFI=0.89). The criterion-related validity was confirmed by the positive correlation between the total scores for ATOP and its subscale scores and the scores for internal weight locus of control. The internal consistency reliability evaluated by Cronbach’s alpha was 0.59-0.71 for the three subscales and the whole scale. The test-retest reliability across two weeks ranged from 0.52 to 0.83. There was a weak negative correlation between body mass index (BMI) and the self-esteem score. Nursing students who perceived themselves as overweight scored lower in the self-esteem factor and higher in the factor of different personality than those who did not. Conclusion The Chinese version of ATOP has satisfactory validity and acceptable reliability in measuring the attitudes toward obese persons, and can be used to evaluate the attitude of nursing students toward obesity. |
