Student engagement, while widely recognized as both important to outcomes of higher education institutions and critical to student learning, is still missing a unifying model addressing students both inside and outside of the classroom. This mixed-methods paper will explore the existing models of student engagement and propose a model which better…

Building on previous studies that formulated measures for assessing self-efficacy beliefs regarding the management of anger/irritation and despondency/sadness, we developed 3 new scales to assess perceived self-efficacy in managing fear, shame/embarrassment, and guilt. In Study 1, the internal and construct validity of the 5 aforementioned…

The present studies aimed to reexamine college students' achievement goal orientations by situating their motivation in a cooperative learning context. The authors proposed and validated a scale of 3 levels of trichotomous achievement goal orientations. In Study 1, confirmatory factor analyses supported that, in laboratory cooperative learning…

Longitudinal validity of Brief Symptom Inventory subscales was examined in a sample (N = 318) with schizophrenia-related illness measured at baseline and every 6 months for 3 years. Nonlinear factor analysis of items was used to test graded response models (GRMs) for subscales in isolation. The models varied in their within-time and between-times…

The authors compared 2-, 3-, 4-factor, and 2-factor/4-facet Psychopathy Checklist-Revised (PCL-R) models in a previously unpublished sample of 1,566 adult male sex offenders assessed under applied clinical conditions as part of a comprehensive state-mandated community notification risk assessment procedure. "Testlets" significantly…

The importance of genetic factors in autism has prompted the development of mutant mouse models to advance our understanding of biological mechanisms underlying autistic behaviors. Mouse models of human neuropsychiatric diseases are designed to optimize (1) face validity, i.e., resemblance to the human symptoms; (2) construct validity, i.e.,…
