> TI Determining Predictor Importance in Hierarchical Linear Models Using
> Dominance Analysis
> SO JOURNAL OF EDUCATIONAL AND BEHAVIORAL STATISTICS
> AB Dominance analysis (DA) is a method used to evaluate the relative
> importance of predictors that was originally proposed for linear
> regression models. This article proposes an extension of DA that allows
> researchers to determine the relative importance of predictors in
> hierarchical linear models (HLM). Commonly used measures of model
> adequacy in HLM (i.e., deviance, pseudo-R(2), and proportional reduction
> in prediction error) were evaluated in terms of their appropriateness as
> measures of model adequacy for DA. Empirical examples were used to
> illustrate the procedures for comparing the relative importance of
> Level-1 predictors and Level-2 predictors in a person-in-group design.
> Finally, a simulation study was conducted to evaluate the performance of
> the proposed procedures and develop recommendations.

> Multiple-Group Bifactor Model
> SO JOURNAL OF EDUCATIONAL AND BEHAVIORAL STATISTICS
> AB The authors present a generalization of the multiple-group bifactor
> model that extends the classical bifactor model for categorical outcomes
> by relaxing the typical assumption of independence of the specific
> dimensions. In addition to the means and variances of all dimensions,
> the correlations among the specific dimensions are allowed to differ
> between groups. By including group-specific difficulty parameters, the
> model can be used to assess differential item functioning (DIF) for
> testlet-based tests. The model encompasses various item response models
> for polytomous data by allowing for different link functions, and it
> includes testlet and second-order models as special cases. Importantly,
> by assuming that the testlet dimensions are conditionally independent
> given the general dimension, the authors show, using a graphical model
> framework, that the integration over all latent variables can be carried
> out through a sequence of computations in two-dimensional subspaces,
> making full-information maximum likelihood estimation feasible for
> high-dimensional problems and large datasets. The importance of relaxing
> the orthogonality assumption and allowing for a different covariance
> structure of the dimensions for each group is demonstrated in the
> context of the assessment of DIF. Through a simulation study, it is
> shown that ignoring between-group differences in the structure of the

> TI Analyzing Response Times in Tests With Rank Correlation Approaches
> SO JOURNAL OF EDUCATIONAL AND BEHAVIORAL STATISTICS
> AB It is common practice to log-transform response times before analyzing
> them with standard factor analytical methods. However, sometimes the
> log-transformation is not capable of linearizing the relation between
> the response times and the latent traits. Therefore, a more general
> approach to response time analysis is proposed in the current
> manuscript. The approach is based on the assumption that the response
> times can be decomposed into a linear function of latent traits and a
> normally distributed residual term after the response times have been
> transformed by a monotone, but otherwise unknown transformation
> function. The proposed model can be fitted by a limited information
> approach, using the matrix of Kendall's tau coefficients and unweighted
> least squares estimation. The transformation function can be determined
> by resorting to discrete time. The proposed approach offers a framework
> for testing model fit by comparing expected and observed correlations
> and for investigating the hypothesis about the form of the
> transformation function. The adequacy of the proposed approaches to
> model calibration and model validation are investigated in a simulation
> study. Two real data sets are analyzed as a demonstration of the model's

> TI Multidimensionality and Structural Coefficient Bias in Structural

> SO EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT
> AB In this study, the authors consider several indices to indicate whether
> multidimensional data are "unidimensional enough" to fit with a
> unidimensional measurement model, especially when the goal is to avoid
> excessive bias in structural parameter estimates. They examine two
> factor strength indices (the explained common variance and omega
> hierarchical) and several model fit indices (root mean square error of
> approximation, comparative fit index, and standardized root mean square
> residual). These statistics are compared in population correlation
> matrices determined by known bifactor structures that vary on the (a)
> relative strength of general and group factor loadings, (b) number of
> group factors, and (c) number of items or indicators. When fit with a
> unidimensional measurement model, the degree of structural coefficient
> bias depends strongly and inversely on explained common variance, but
> its effects are moderated by the percentage of correlations
> uncontaminated by multidimensionality, a statistic that rises
> combinatorially with the number of group factors. When the percentage of
> uncontaminated correlations is high, structural coefficients are
> relatively unbiased even when general factor strength is low relative to
> group factor strength. On the other hand, popular structural equation
> modeling fit indices such as comparative fit index or standardized root
> mean square residual routinely reject unidimensional measurement models
> even in contexts in which the structural coefficient bias is low. In

> Rasch Model That Dispels Any "Threshold Disorder Controversy"
> SO EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT
> AB Responses to items with formats in more than two ordered categories are
> ubiquitous in education and the social sciences. Because the putative

> relationships among response spaces from which a space of experimentally
> independent Bernoulli variables, characterized by Rasch's simple
> logistic model, can be inferred. From this inference, the article
> establishes the necessary and sufficient evidence to test the hypothesis
> that the required ordering of the categories is an empirical property of
> the assessments. This expanded derivation, which exposes how Adams, Wu,
> and Wilson (2012) misconstrue the model and its implications, is
> intended to dispel the so-called disordered threshold controversy they

> SO EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT
> AB There is a continuing tension in testing programs to equate forms and

> SO READING RESEARCH QUARTERLY
> AB This study modeled the interrelationships of reading instruction,
> motivation, engagement, and achievement in two contexts, employing data
> from 1,159 seventh graders. In the traditional reading/language arts
> (R/LA) context, all students participated in traditional R/LA
> instruction. In the intervention R/LA context, 854 students from the
> full sample received Concept-Oriented Reading Instruction (CORI) while
> the remainder continued to receive traditional R/LA. CORI emphasizes

> were included: four motivations that are usually positively associated
> with achievement (intrinsic motivation, self-efficacy, valuing, and
> prosocial goals) and three motivations that are usually negatively
> associated with achievement (perceived difficulty, devaluing, and
> antisocial goals). Reading engagement was also represented by positive
> and negative constructs, namely dedication to and avoidance of reading.
> Gender, ethnicity, and income were statistically controlled in all
> analyses. In the traditional R/LA context, a total network model
> prevailed, in which motivation was associated with achievement both
> directly and indirectly through engagement. In contrast, in the
> intervention R/LA context, a dual-effects model prevailed, in which
> engagement and achievement were separate outcomes of instruction and
> motivation. The intervention R/LA context analyses revealed that CORI
> was associated with positive changes in motivation, engagement, and
> achievement relative to traditional R/LA instruction. The discussion
> explains why there were different relations in the two instructional

> TI Cognitive ability in early adulthood is associated with later suicide
> and suicide attempt: the role of risk factors over the life course
> SO PSYCHOLOGICAL MEDICINE
> AB Background. Cognitive ability/intelligence quotient (IQ) in youth has
> previously been associated with subsequent completed and attempted
> suicide, but little is known about the mechanisms underlying the
> associations. This study aims to assess the roles of various risk
> factors over the life course in explaining the observed relationships.
> Method. The present investigation is a cohort study based on data on IQ
> test performance and covariates, recorded on 49 321 Swedish men
> conscripted in 1969-1970, at ages 18-20 years. Information on suicides
> and hospital admissions for suicide attempt up to the age of 57 years,
> childhood and adult socio-economic position, and adult family formation,
> was obtained from linkage to national registers.
> Results. Lower IQ was associated with increased risks of both suicide
> and suicide attempt during the 36 years of follow-up. The associations
> followed a dose-response pattern. They were attenuated by approximately
> 45% in models controlling for social background, mental ill-health,
> aspects of personality and behavior, adult socio-economic position and
> family formation. Based on one-unit decreases in IQ test performance on
> a nine-point scale, the hazard ratios between ages 35 and 57 years were:
> for suicide 1.19 [95% confidence interval (CI) 1.13-1.25], fully
> adjusted 1.10 (95% CI 1.04-1.18); and for suicide attempt 1.25 (95% CI
> 1.20-1.31), fully adjusted 1.14 (95% CI 1.09-1.20).
> Conclusions. Cognitive ability was found to be associated with
> subsequent completed and attempted suicide. The associations were
