Formulas for the asymptotic biases of the parameter estimates in structural equation models are provided in the case of the Wishart maximum likelihood estimation for normally and nonnormally distributed variables. When multivariate normality is satisfied, considerable simplification is obtained for the models of unstandardized variables. Formulas…

In this study, a two-group structural equation model was proposed and tested to investigate the change in faculty members' perceptions of their worklife and satisfaction over time. Using the National Study of Postsecondary Faculty [i.e., NSOPF:93-99, National Center for Educational Statistics, US Department of Education, National Study of…

Extending B. L. Fredrickson's (1998) broaden-and-build theory of positive emotions and M. Losada's (1999) nonlinear dynamics model of team performance, the authors predict that a ratio of positive to negative affect at or above 2.9 will characterize individuals in flourishing mental health. Participants (N=188) completed an initial survey to…

This study examined the mediating roles of perceived social support and psychological distress on the relationship between adult attachment and help-seeking intentions. Participants were 355 college students at a large Midwestern university. The structural equation model results indicated that attachment anxiety in individuals was positively…

This study examined basic psychological needs satisfaction (i.e., the need for autonomy, competence, and relatedness) as a mediator between adult attachment (i.e., anxiety and avoidance) and distress (i.e., shame, depression, and loneliness). A total of 299 undergraduates from a Midwestern university participated. Results from structural equation…

Object perception requires interpolation processes that connect visible regions despite spatial gaps. Some research has suggested that interpolation may be a 3-D process, but objective performance data and evidence about the conditions leading to interpolation are needed. The authors developed an objective performance paradigm for testing 3-D…

The article uses confirmatory factor analysis (CFA) as a template to explain didactically multilevel structural equation models (ML-SEM) and to demonstrate the equivalence of general mixed-effects models and ML-SEM. An intuitively appealing graphical representation of complex ML-SEMs is introduced that succinctly describes the underlying model and…

L. L. Thurstone's (1927) model provides a powerful framework for modeling individual differences in choice behavior. An overview of Thurstonian models for comparative data is provided, including the classical Case V and Case III models as well as more general choice models with unrestricted and factor-analytic covariance structures. A flow chart…

Purpose: The purpose of this study was to assess the direction and magnitude of the effects among the components of resident satisfaction in residential aged care and to examine if the relationships among satisfaction components vary according to facility type (i.e., nursing home and hostel). Briefly, a hostel is a low-care facility in which…

Objective: To evaluate the substance use pathways of minority adolescents with a structural equation modeling (SEM) based on the social ecological model. Method: Seven hundred ninety adolescents completed the baseline survey questionnaire for the Center for Substance Abuse Prevention's Mentoring and Family Strengthening Initiative. The exogenous…

Based on studies carried out on qualitative data an instrument was constructed for investigating how larger numbers of students handle graphics. This test, consisting of 18 pages, each with its own graphic display(s) and a set of tasks, was distributed to 363 students, 15-16 years of age, from five different schools. The format of the questions…

In the No Child Left Behind Act and the What Works Clearinghouse, the federal government has attempted to establish guidelines for the type of education research that U.S. schools should consider in selecting instructional programs and resources. The government's clear preference for the medical model--a powerful research design in such fields as…

This study investigated the role of metacognition as a mediator of the effect of test anxiety on a surface approach to studying. The following scales were completed by 109 undergraduate social sciences students: Approaches and Study Skills Inventories for Students (ASSIST), Metacognitions Questionnaire (MCQ), and Test Anxiety Scale (TAS). Positive…

The effects of anger feelings (rated by the State-Trait Anger Expression Inventory) and witnessing family violence on anxiety and depression (rated by the Hospital Anxiety and Depression Scale) were examined in 457 junior high school students. Anxiety and depression scores were correlated with frequencies of witnessing family violence. In a…

Recent theoretical advances in working memory guided analyses of cognitive measures in 122 children with dyslexia and their 200 affected biological parents in families with a multigenerational history of dyslexia. Both children and adults were most severely impaired, on average, in three working memory components- phonological word-form storage,…
