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…

Most psychometric tests of spatial ability are paper-and-pencil tasks at the ''figural'' scale of space, in that they involve inspecting, imagining or mentally transforming small shapes or manipulable objects. Environmental spatial tasks, such as wayfinding or learning the layout of a building or city, are carried out in larger spaces that…

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…

An ecological model of ethnic identity was examined among 639 adolescents of Asian Indian, Chinese, Filipino, Vietnamese, and Salvadoran descent. Using structural equation modeling and, specifically, multiple group comparisons, findings indicated that familial ethnic socialization (FES) played a significant role in the process of ethnic identity…

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: This article discusses continued development of the Urban Hassles Index (UHI). The stressors identified in the UHI are chronic and differ substantively from the more acute life events indexes typically employed to measure adolescent stress. Method: Exploratory factor analysis was used to identify the underlying factor structure of the…

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…

According to the domain-specific, multilevel homework model proposed in the present study, students' homework effort is influenced by expectancy and value beliefs, homework characteristics, parental homework behavior, and conscientiousness. The authors used structural equation modeling and hierarchical linear modeling analyses to test the model in…

The nonlinear random coefficient model has become increasingly popular as a method for describing individual differences in longitudinal research. Although promising, the nonlinear model it is not utilized as often as it might be because software options are still somewhat limited. In this article we show that a specialized version of the model…
