大学生网络利他行为量表在中学生中的信效度检验

Internet altruistic behavior scale for undergraduates： reliability and validity for middle school students

目的探讨大学生网络利他行为量表（IABSU）在中学生中的适用性。方法首先对402名中学生进行问卷调查，用内在一致性a系数、分半信度和重测信度检验量表的信度，用验证性因素分析检验因子结构，然后再对375名中学生施测，进行交互效度的检验。结果量表的d系数、分半信度和重测信度分别为0．934、0．887和0．838，各维度的a系数在0．757—0．886之间，分半信度在0．721—0．846之间，重测信度在0．714—0．811之间；验证性因素分析在中学生中验证了量表原有的因子结构；量表的结构模型在中学生中具有相当的稳定性，交互效度很好；量表具有较好的效标效度。结论IABSU适用于中学生。

Objective To investigate the reliability and validity of interuet altruistic behavior scale for undergraduates （IABSU） for middle school students. Methods 402 middle school students were investigated by IABSU. The reliability was examined by alpha coefficient and split-half coefficient, while the validity was examined by confirmatory factor analysis. Then 375 middle school students were investigated, and cross-validation was examined. Results The alpha coefficient, split-half coefficient and test-retest reliability for IABSU were 0. 934,0. 887 and O. 838 respectively,the alpha coefficient for the dimensions ranged from 0.757 to 0. 886, split-half coefficiem from 0.721 to 0. 846,test-retest reliability from 0. 714 to 0. 811. The structure of the scale had been proved by confirmatory factor analysis. The structure of the scale for middle school students was very stability, and the crossvalidation was very good, Criterion-related validity of the scale was good, Conclusion IABSU can apply to middle school students.
