The Questionnaire for Autism Spectrum Conditions (Q-ASC) was developed by Attwood et al. (2011) to identify gender-sensitive profiles of autism symptomatology; prioritise and adjust the direction of clinical interventions; and support positive psychosocial outcomes and prognosis into adulthood. The current research piloted the Q-ASC with parents…

In recent years, the social sciences have seen a resurgence in the study of divergent thinking (DT) measures. However, many of these recent advances have focused on abstract, decontextualized DT tasks (e.g., list as many things as you can think of that have wheels). This study provides a new perspective by exploring the reliability and validity…

This study tested five confirmatory factor analytic (CFA) models of the Positive Affect Negative Affect Schedule (PANAS) to provide validity evidence based on its internal structure. A sample of 223 club sport athletes indicated their emotions during the past week. Results revealed that an orthogonal two-factor CFA model, specifying error…

This paper illustrates that the psychometric properties of scores and scales that are used with mixed-format educational tests can impact the use and interpretation of the scores that are reported to examinees. Psychometric properties that include reliability and conditional standard errors of measurement are considered in this paper. The focus is…

Despite decades of research and debate, the issue of unequal outcomes continues to be a concern in educational systems worldwide. In England, published data relating to pupils' attainment across ethnic groups and by class indicators has been used to demonstrate continued inequalities in schools. This article attempts to deconstruct the…

An efficient algorithm for maximizing split-half reliability coefficients is described. Coefficients derived by the algorithm were found to be generally larger than odd-even split-half coefficients or other internal consistency measures and nearly as large as the largest split half coefficients. MSPLIT, Odd-Even, and Kuder-Richardson-20…

Finding and interpreting lower bounds for reliability coefficients for tests with nonhomogenous items has been a problem for psychometricians. This paper presents a mathematical formula for finding the greatest lower bound for such a coefficient. (Author/JKS)

An investigation of three intelligence tests reveals that the Slosson shows signs of becoming a legitimate substitute for other intelligence tests, while the Columbia yielded erratic results for the mentally retarded participants in this study. (Author/KM)

Fabricated test protocols were used to study how effectively examiners agree in scoring ambiguous WISC-R responses. The results suggest that, even with the improved WISC-R manual, scoring remains a difficult and challenging task. (Author)

While a variety of scales and instruments to measure parental support exist, most of these have not received adequate analysis. Utilizing two bodies of data, the widely used Heilbrun, Cornell, and Schaefer measures of parental support were examined. Results are presented. (Author)

Two problems in the investigation of predictive bias in tests, the effect of unreliability of the predictors, and the effect of excluding a predictor from the regression equation on which there are preexisting group differences, are discussed. (Author)

Comparison of the Goodenough-Harris and McCarthy scoring procedures for 60 kindergarten children's drawings yielded substantial agreement between the two scoring systems. The streamlined McCarthy scoring system should be utilized when large numbers of children are being evaluated with short periods of time. (Author)

Rasch and classical test analysis methods were compared with respect to their similarities and differences in the identification of noninformative items and implausible person records. Using computer simulated data with known parameters, each model was evaluated in terms of its effectiveness in: (1) identifying noninformative or "bad"…

Compared Kuder-Richardson Formula 20 and coefficient alpha (by blocks) reliability estimates for a reading comprehension test. On the average, K-R 20 exceeded coefficient alpha by about .05; that is, K-R 20 exaggerated the internal consistency of the test as would be expected from theory. Implications for counseling interpretations are discussed.…
