Because variables may be correlated in the social and behavioral sciences, multicollinearity might be problematic. This study investigates the effect of collinearity manipulated in within and between levels of a two-level confirmatory factor analysis by Monte Carlo simulation. Furthermore, the influence of the size of the intraclass correlation…

We surveyed Australian adolescents and parents to test differences and congruence in perceptions of adolescent career development tasks (career planning, exploration, certainty, and world-of-work knowledge) and vocational identity. We found that, for adolescents (N = 415), career development tasks (not career exploration) explained 48% of the…

We examined the association between peer-assessed emotional expressivity and children's status in the peer group after controlling for social behavior. Participants were 417 elementary school children (X-bar age = 10 years) from a Midwestern urban community and their teachers. Hierarchical multiple regression analyses were used. After controlling…

This study explored motivation and engagement among 585 Jamaican middle and high school students. Motivation and engagement were assessed via students' responses to the Motivation and Engagement Scale. Confirmatory factor analysis (CFA) found satisfactory fit, and by most measures, multigroup CFA demonstrated comparable factor structure for males…

This study examined how the perception of a linkage between organizational ethical behavior and career success, representing ethical orientation of the organization, influences employees' perceptions of organizational politics and their subsequent career motivation, that is, career commitment, motivation to participate in training, and turnover…

This paper introduces a two-dimensional Item Response Theory (IRT) model to deal with nonignorable nonresponses in tests with dichotomous items. One dimension provides information about the omitting behavior, while the other dimension is related to the person's "ability". The idea of embedding an IRT model for missingness into the measurement…

To investigate the developmental course of aggression and peer victimization in childhood and adolescence, distinct subgroups of children were identified based on similarities and differences in their physical, verbal and relational aggression, and victimization. Developmental continuity and change were assessed by examining transitions within and…

This study explores the constructs that underpin three different measures of vocabulary knowledge and investigates the degree to which these three measures correlate with, and are able to predict, measures of second language (L2) listening and reading. Word frequency structured vocabulary tests tapping "receptive/orthographic (RecOrth)…

We assessed the extent to which feelings of sympathy and aggressive behaviors codeveloped from 6 to 12 years of age in a representative sample of Swiss children (N = 1,273). Caregivers and teachers reported children's sympathy and overt aggression in 3-year intervals. Second-order latent curve models indicated general mean-level declines in…

This paper investigates the direct and indirect ties between various leadership styles, namely, instructional, transformational, transactional, and laissez-faire leadership, and the instructional practices of teachers by applying a structural equation model. For this purpose, we analyzed survey data of n = 3,746 teachers from 126 schools collected…

Although previous studies have reported that the broad autism phenotype is associated with reduced relationship quality within established relationships, understanding how this association emerges requires assessment prior to relationship development. In the present longitudinal study, college roommates with minimal familiarity prior to…

The current study examined school-level victimization as a moderator of associations between peer victimization and changes in 2 types of self-blaming attributions, characterological and behavioral, across the first year of middle school. These associations were tested in a large sample (N = 5,991) of ethnically diverse adolescents from fall to…

This study investigated associations of general and specific parental self-efficacy factors with bullying and peer victimization behaviors among 142 fourth and fifth graders and their parents. Using structural equation modeling, exploratory factor analysis was used to examine one general parenting self-efficacy measure and a bullying-specific…

Framed from an integrative approach, the current article examined the associations between ethnic identity exploration (EIE), ethnic identity commitment (EIC), and acculturative stress by investigating the mediating role of ethnic attitudes (i.e., in-group favoritism and out-group derogation) in these relationships. Additionally, the moderating…

Research is currently testing how the new maladaptive personality inventory for DSM (PID-5) and the well-established common Five-Factor Model (FFM) together can serve as an empirical and theoretical foundation for clinical psychology. The present study investigated the official short version of the PID-5 together with a common short version of…
