Data were collected about 95 fourth-grade and fifth-grade children from three sources (teachers, parents, and children) on four constructs related to aggression (proactive aggression, reactive aggression, callous-unemotional traits, and anger dysregulation) by using a multitrait-multimethod design. Two goals were addressed through a…

In many intervention and evaluation studies, outcome variables are assessed using a multimethod approach comparing multiple groups over time. In this article, we show how evaluation data obtained from a complex multitrait-multimethod-multioccasion-multigroup design can be analyzed with structural equation models. In particular, we show how the…

The distinctiveness of physical aggression from other antisocial behavior is widely accepted but little research has explicitly focused on young children to empirically test this assumption. A Multitrait-Multimethod Matrix (MTMM) approach was employed to confirm the distinctiveness of physical aggression from nonaggressive antisocial behavior in…

Teachers' ratings of problem behaviors are gathered as a matter of course in psychological evaluations of children. Teacher ratings are weighted heavily in the results of educational evaluations (Frick et al., 2010). With such heavy emphasis on teacher behavioral ratings, it is important to understand the extent to which conflict between…

Existing research posits multiple dimensions of bullying and victimization but has not identified well-differentiated facets of these constructs that meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors that are not so highly correlated as to detract…

Using longitudinal data collected over 2 years on a sample of 2,745 urban elementary school children (1st-6th graders, ages 6-11 years) from economically disadvantaged communities, effects of stressful experiences within 3 contexts (school, family, neighborhood), cumulative stress, and multiple context stress on 3 indices of children's adjustment…

In this article we present a cognitive-ecological model for understanding and preventing emotional and behavioral difficulties and propose directions for school-based intervention programs, particularly with aggressive children. In the cognitive-ecological framework, intervention efforts should target certain cognitive skills (e.g., skills that…

A multimethod, multitrait approach was used to examine the relations of aggression and hyperactivity to mastery motivation in preschool children. Parallel measures of multiple facets of mastery motivation were devised from findings in two studies: (study 1) a maternal report questionnaire for 332 twins, ages 3-5, recruited from the twin registry…
