青少年病理性互联网使用量表的项目反应理论分析

An Item Response Theoretical Analysis on the Internet-use Scale for Adolescent Pathological Cases

考察青少年病理性互联网使用量表的项目和测验性能,为该量表的使用提供一定的参考.通过青少年病理性互联网使用量表对705名中学生进行施测,并使用项目反应理论对该量表进行分析.研究结果显示,从参数估计的结果看,除了项目5的难度太大,超过了理论取值范围以外,其余项目的难度和区分度均符合理论要求.从信息量的结果看,大部分项目的质量良好,项目8、9、12和17的质量一般,需要进行修改,项目2、5、6、25、34、35和36的质量较差,需要进行重新拟定.由此得出,青少年病理性互联网使用量表的整体编制质量较好,部分项目需要进行修改或重新拟定.

This paper studies the properties of internet--use scale for adolescent pathological cases, which provide certain basis for the use of this scale. Method： 705 middle school students were tested by the adolescent pathological internet - use scale,and then analyzed by item response theory. From the results of parameter estimation, we find that the items conform to the basic requirements of item response theory except that the difficulty of item5 exceeds the range of theoretical value. From the results, we find that most of the items are in good quality,but item 8, item 9, item 12 and item 17 are in general quality which need to be modified,and item 2, item 5, item 6, item 25, item 34, item 35 and item 36 are in poor quality which need to be rewritten. The overall quality of adolescent pathological internet scale is good, but some items need to be modified or rewritten.
