Abstract
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.
