目的:研制适用于中国初中生的吸烟相关态度量表。方法:参考国内外文献设计了16个条目的吸烟相关态度量表。用因子分析评价结构效度;比较尝试吸烟者与未吸烟者、男生与女生的差异来评价区分效度;用Cronbach’α系数和折半信度来评价量表的信度;比较前后两次测量的差异与相关系数来评价重测信度。结果:因子分析提取两个主成分解释总变异的46.2%,旋转后因子1定义为对烟草及吸烟相关行为的认同,因子2定义为对控烟措施的认同;女生态度得分高于男生,未吸烟者的得分高于尝试吸烟者。两个因子和所有条目的α系数分别为0.87、0.75和0.86,折半信度分别为0.71、0.59和0.72。重测(112人)相关系数分别为0.72、0.44和0.67,关联均有显著性;两次调查结果接近,差异无显著性。结论:该量表具有较好的效度和信度,可以为国内类似调查提供参考。
Objective: To develop a smoking-related attitude scale suitable for junior high school students in China. Methods: Reference to domestic and foreign literature designed 16 items of smoking related attitude scale. The structural validity was evaluated by factor analysis. The discriminant validity was evaluated by comparing the differences between smoker and non-smoker, boys and girls. The reliability of scale was evaluated by Cronbach’α coefficient and half-reliability. The difference and the correlation coefficient to evaluate the retest reliability. Results: Two principal components were extracted from factor analysis to explain 46.2% of the total variance. Factor 1 after rotation was defined as tobacco and smoking-related behaviors. Factor 2 was defined as approval of tobacco control measures. Female attitude scores were higher than boys and no smoking Those who score higher than those who try smokers. The alpha coefficients for the two factors and all entries were 0.87, 0.75 and 0.86, respectively, and the half-confidences were 0.71, 0.59 and 0.72, respectively. The correlation coefficients of retest (112 persons) were 0.72, 0.44 and 0.67, respectively, and the correlations were significant. The results of two surveys were similar with no significant difference. Conclusion: The scale has good validity and reliability, which can provide reference for similar domestic surveys.
