Diagnosing autism and PDD-NOS at very early ages has become a major priority in the field of mental health. More recently, researchers have also come to realize the importance of identifying co-occurring conditions of psychopathology in this population. In the present study, 309 children between 17 and 37 months of age who had been identified as…

Battered women's stages of change (SOCs) are examined in this study. First, confirmatory factor analysis and latent profile analysis were conducted on 754 battered women's responses on the Problems in Relationship Scale (Brown, 1998). Factor loadings were strong, and latent variable mixture modeling produces a two-class solution. Second,…

In this commentary, the author addresses what is referred to as the deterministic input, noisy "and" gate (DINA) model. The author mentions concerns with how this model has been formulated and presented. In particular, the author points out that there is a lack of recognition of the confounding of profiles that generally arises and then discusses…

Rupp and Templin (2008) do a good job at describing the ever expanding landscape of Diagnostic Classification Models (DCM). In many ways, their review article clearly points to some of the questions that need to be answered before DCMs can become part of the psychometric practitioners toolkit. Apart from the issues mentioned in this article that…

Though group interventions are widely used in community-based and clinical settings, there are few brief instruments for assessing the group environment. Two studies on the development of a brief measure to assess intervention group environments are described, and psychometric properties of the new scale are presented. The new measure is based on…

This study aimed at investigating the psychometric properties of two inventories for the measurement of learning style preferences in a Greek sample: Kolb's (1985) Learning Style Inventory (LSI) and the Index of Learning Styles (ILS) by Felder & Soloman (1999). The inventories were administered in a total of 340 Greek university undergraduate…

Large-scale assessment programs are becoming increasingly common throughout Canada and the United States. Given the emphasis on inclusive education in North America, special education students are largely expected to participate in these programs. However, several challenges exist for educators, policymakers, and psychometricians with respect to…

This study was a preliminary examination of the psychometric properties of a newly developed Spanish translated version of the "Gifted Rating Scales-School Form (GRS-S)". Data was collected from elementary and middle schools in northeastern Puerto Rico. Thirty teachers independently rated 153 students using the "GRS-S" Spanish…

The objectives of this article are, first, to provide a brief review of screening and assessment of adolescents substance use and substance use disorders; second, to describe the work done with the Teen Addiction Severity Index (T-ASI) in different countries; and third, to address challenges and opportunities in order to improve international…

Course management systems (CMSs) support thousands of courses at colleges and universities worldwide, delivering fully online courses as well as supplementing traditional face-to-face instruction. While quite a few studies have focused on the numerous benefits and technological advantages of CMSs, there is a paucity of empirical work focused on…

The study reported in this paper, a Multistage Longitudinal Comparative (MLC) Design Stage II evaluation conducted as a planned preliminary efficacy evaluation (psychometric evaluation of measures, short-term controlled outcome studies, etc.) of the Changing Lives Program (CLP), provided evidence for the reliability and validity of qualitative…

Most students have some experience with purported measures of psychological constructs before entering college. Critical analysis of such measures requires familiarity with test development strategies. The activities outlined in this article allowed students to complete the steps involved in scale construction and empirical analysis in a…

This study investigated the psychometric properties and predictive validity of three self-report scales (the Psychopathy Content Scale, the Psychopathy-16 scale, and the Egotistic scale) derived from the Millon Adolescent Clinical Inventory (MACI) to screen for the presence of psychopathic and narcissistic personality characteristics. Exploratory…

Confirmatory factor analysis with robust weighted least squares estimation of the 103 dichotomously scored items of the Child Behavior Checklist/6-18 (T. M. Achenbach & L. A. Rescorla, 2001) in a sample of 516 girls adopted from China (ages 6.0-15.7 years; M = 8.2, SD = 1.9) indicated that the fit of the 8-factor model was good…
