目的考察自制的青少年思想道德问卷在汶川地震灾区应用的信度效度。方法采用分层整群抽样方法,抽取7~20岁灾区青少年共6 300名,使用自制问卷调查,应用crobach’α系数和分半信度考评其信度,应用探索性因子分析和验证性因子分析方法考评其效度。结果问卷总的内部一致性和分半信度分别为0.766、0.627,问卷信度不差;效度考评方面,探索性因子分析提取了10个公因子,累积贡献57.68%,其中外部支持因子的贡献率最大,为16.94%。验证性因子分析表明,在对部分条目进行删减和调整归类后,问卷效度得到较大改善,RMSEA=0.079,且条目的归类也更为合理。问卷的6个因子间,“不良生活习惯”和“电视及网络成瘾情况”存在正相关,“外部支持”与“故意伤害”存在负相关。结论自制的青少年思想道德问卷在地震灾区应用的信度效度较好,可以接受。

Exploratory factor analysis and confirmatory factor Analysis method to evaluate its validity. The results of the questionnaire total internal consistency and half the reliability were 0.766,0.627, the questionnaire reliability is not bad; validity evaluation, exploratory factor analysis extracted 10 common factors, the cumulative contribution of 57.68%, of which external support factors The largest contribution rate was 16.94%. Confirmatory factor analysis showed that the validity of the questionnaire was greatly improved after subtracting and adjusting some of the items.
