摘要
摘要:本文探讨了巴拉特冲动量表(BIS)在提供结构效度证据方面存在的问题。由于该量表的简短版本(BIS-15)的德文译本与英文原版一样,包含了几对项目陈述高度相似的项目,因此我们假设高子集同质性(HSH)是这些问题的根源。高子集同质性(HSH)指的是量表中某一子集项目比其余项目显示出更大程度的同质性。我们以 287 名大学生为样本,通过仅包含 BIS 因子的确认性因子分析(CFA)模型和额外包含 HSH 因子的模型对 BIS 数据进行了研究。在不包含 HSH 因子的模型中,模型拟合度较低,而在包含 HSH 因子的模型中,模型拟合度较高。这些结果表明,BIS 项目基本上具有结构效度,但这种效度受到了 HSH 的影响。
High Subset Homogeneity Impairs Structural Validity of the Barratt Impulsiveness Scale
Abstract: Problems in providing evidence of structural validity of the Barratt Impulsiveness Scale (BIS) are addressed. As the German translation of a short version of the scale (BIS-15) included pairs of items with highly similar item statements, like the original English version, we hypothesized high subset homogeneity (HSH) as the source of these problems. HSH denotes a situation in which a subset of items shows a larger degree of homogeneity than the remainder of the items of the scale. In a sample of 287 university students, we investigated BIS data by means of confirmatory factor analysis (CFA) models including BIS factors only and models additionally including HSH factors. Whereas the models without HSH factors yielded model misfit, good model fit was observed for the models with HSH factors. These results suggested that BIS items basically showed structural validity, but this validity was impaired by HSH.
期刊介绍:
Researchers, teachers, and students interested in all areas of individual differences (e.g., gender, temperament, personality, intelligence) and their assessment in human and animal research will find the Journal of Individual Differences useful. The Journal of Individual Differences publishes manuscripts dealing with individual differences in behavior, emotion, cognition, and their developmental aspects. This includes human as well as animal research. The Journal of Individual Differences is conceptualized to bring together researchers working in different areas ranging from, for example, molecular genetics to theories of complex behavior.
