Aiello, Rachel; Ruble, Lisa; Esler, Amy – Journal of Applied School Psychology, 2017
This study aimed to better understand predictors of evidence-based assessment practices for autism spectrum disorder (ASD). Nationwide, 402 school psychologists were surveyed for their knowledge of and training and experience with ASD on assessment practices, including reported areas of training needs. The majority of school psychologists reported…

Harrison, Allyson G.; Holmes, Alana; Silvestri, Robert; Armstrong, Irene T. – Journal of Psychoeducational Assessment, 2015
Miller et al. have challenged the findings of our two previous studies, based largely on the assumption that our findings are biased due to the clinical sample used. However, they fail to address the primary tenet of our studies, namely, that clinicians will obtain different scores on the Wechsler Adult Intelligence Scale-IV (WAIS-IV) depending on…

Harrison, Allyson G.; Holmes, Alana; Silvestri, Robert; Armstrong, Irene T. – Journal of Psychoeducational Assessment, 2015
Building on a recent work of Harrison, Armstrong, Harrison, Iverson and Lange which suggested that Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) scores might systematically overestimate the severity of intellectual impairments if Canadian norms are used, the present study examined differences between Canadian and American derived…

Miller, Jessie L.; Weiss, Lawrence G.; Beal, A. Lynne; Saklofske, Donald H.; Zhu, Jianjun; Holdnack, James A. – Journal of Psychoeducational Assessment, 2015
It is well established that Canadians produce higher raw scores than their U.S. counterparts on intellectual assessments. As a result of these differences in ability along with smaller variability in the population's intellectual performance, Canadian normative data will yield lower standard scores for most raw score points compared to U.S. norms.…

Zhang, Wei; Niu, Weihua – Journal of Creative Behavior, 2013
This study examined a total of 140 elderly Chinese from China and the United States to investigate the relationship between attitude toward aging, daily activities, general health, education, and other demographics and rated creativity as measured by collage making and storytelling. The result of this study shows that creativity declines with age.…

Roivainen, Eka – International Journal of Testing, 2013
To study the concept of national IQ profile, we compared U.S. and Finnish WAIS, WAIS-R, and WAIS III nonverbal and working memory subtest norms. The U.S. standardization samples had consistently higher scores on the Coding and Digit span subtests, while the Finnish samples had higher scores on the Block design subtest. No stable cross-national…

Bowden, Stephen C.; Saklofske, Donald H.; Weiss, Lawrence G. – Assessment, 2011
Examination of measurement invariance provides a powerful method to evaluate the hypothesis that the same set of psychological constructs underlies a set of test scores in different populations. If measurement invariance is observed, then the same psychological meaning can be ascribed to scores in both populations. In this study, the measurement…

Bowden, Stephen C.; Saklofske, Donald H.; Weiss, Lawrence G. – Educational and Psychological Measurement, 2011
A measurement model describes both the numerical and theoretical relationship between observed scores and the corresponding latent variables or constructs. Testing a measurement model across groups is required to determine if the tests scores are tapping the same constructs so that the same meaning can be ascribed to the scores. Contemporary tests…

Roivainen, Eka – Intelligence, 2010
For this study, European WAIS III performance subtest norms were compared to the original US norms. When European WAIS III raw scores were scored using US norms, the resulting perceptual organization index (POI) means were significantly higher than the processing speed index (PSI) means. The POI/PSI difference is roughly 5-10 points for the German…
