Objective: Morningness is a stable characteristic of individuals, related to impulsivity and novelty seeking. The evening orientation is a risk factor for psychiatric conditions such as depression and personality disorders. The authors hypothesized that adults suspected of having ADHD are more evening oriented than adults without ADHD. Method:…

Purpose: The purpose of this paper is to analyze the construct validity of learning transfer system inventory (LTSI) for use in Portugal. Furthermore, it also aims to analyze whether LTSI dimensions differ across individual variables such as gender, age, educational level and job tenure. Design/methodology/approach: After a rigorous translation…

This article describes the development of the Latino/a Values Scale (35 items, 14 reverse-worded). Evidence of reliability and validity are presented on the basis of three studies. An examination of the factor structure of the items suggests the presence of the following dimensions: cultural pride, simpatia, familismo, and espiritismo. (Contains 4…

Authorial identity is the sense a writer has of themselves as an author and the textual identity they construct in their writing. This article describes two studies exploring psychology students' authorial identity in academic writing. A qualitative focus group study with 19 students showed that authorial identity was largely unfamiliar to…

The psychometric properties of scores from the Achievement Goal Questionnaire were examined in samples of Japanese (N = 326) and Canadian (N = 307) postsecondary students. Previous research found evidence of a four-factor structure of achievement goals in U.S. samples. Using confirmatory factor-analytic techniques, the authors found strong…

Nesselroade, Gerstorf, Hardy, and Ram (this issue) propose to "filter out" idiosyncrasies of dynamic processes at the level of the individual through the application of dynamic factor analysis. The problem that they deal with is that individuals may differ in the items that are "salient" for a given construct, so that the same measurement model…

This study investigates the effects of sample size, factor overdetermination, and communality on the precision of factor loading estimates and the power of the likelihood ratio test of factorial invariance in multigroup confirmatory factor analysis. Although sample sizes are typically thought to be the primary determinant of precision and power,…

The primary purpose of this study was to develop and field test the ExCEL survey instrument, intended to measure faculty attitudes toward and perceptions about students with disabilities at four-year colleges and universities. A secondary purpose was to examine how demographic characteristics of the sample and prior disability-focused training…

Federal legislation such as "No Child Left Behind" mandated that students with disabilities be included in accountability standards, creating an important responsibility to fairly assess all students, even those with disabilities. Consequently, a sense of urgency was placed on the entire educational system to ensure that these students…

Amotivation refers to a state in which individuals cannot perceive a relationship between their behavior and that behavior's subsequent outcome. With the belief that considering amotivation as a multidimensional construct could reflect the complexity of motivational deficits in physical education, we developed this study to validate an amotivation…

This study investigated cultural identity and peer influence on tobacco, alcohol, and cannabis use in a culturally diverse sample of Northern Australian adolescents. Middle school students (n = 274) completed the Multigroup Ethnic Identity Measure (MEIM) and measures of their own and perceived friends' substance use. Higher scores on the full…

Counselors, psychologists, and evaluators of intervention programs for youth increasingly view the promotion of connectedness as an important intervention outcome. When evaluating these programs, researchers frequently test whether the treatment effects differ across gender and ethnic or racial groups. Doing so necessitates the availability of…

This study examined the factorial structure of three related constructs, math self-concept, math self-efficacy, and math anxiety, across 41 countries. One factorial structure was achieved at both between- and within-country levels. Within-country variations of the self-constructs were also noted in relation to math performance: Self-concept showed…

Two studies describe the development of a comprehensive, vignette-based measure of social information processing (SIP) particularly relevant for children with internalizing problems. Study 1 (N = 219 3rd-6th graders) describes the creation of the Children's Evaluation of Everyday Social Encounters Questionnaire (ChEESE-Q) and evidence for its…

We examined the validity of the factor structure and invariance of the Perceived Locus of Causality (PLOC) scale instrument scores across two nations endorsing collectivist (Singapore) and individualist (Great Britain) cultural values. Results indicated that confirmatory factor analytic models of the PLOC exhibited adequate ft according to…
