BACKGROUND The Center for Epidemiologic Studies Depression Scale (CES-D; Radloff, 1977) is a commonly used freely available self-report measure of depressive symptoms. Despite its popularity, several recent investigations have called into question the robustness and suitability of the commonly used 4-factor 20-item CES-D model. The goal of the current study was to address these concerns by conf...

Rationale In order to avoid response bias such as agreement bias or acquiescence, it was a common recommendation that both positively-and negatively-worded items should be included in survey that the practice of using positively-and negatively-worded items may introduce systematic measurement errors that disrupt analyses and interpretations of the results (DiStefano & Motl, 2006; Quilty, Oakman...

Validation is an important enterprise especially when a test is a high stakes one. Demographic variables like gender and field of study can affect test results and interpretations. Differential Item Functioning (DIF) is a way to make sure that a test does not favor one group of test takers over the others. This study investigated DIF in terms of gender in the reading comprehension subtest (35 i...

We investigated measurement equivalence in two antisocial behavior scales (i.e., one scale for adolescents and a second scale for young adults) by examining differential item functioning (DIF) for respondents from single-parent (n = 109) and two-parent families (n = 447). Even though one item in the scale for adolescents and two items in the scale for young adults showed significant DIF, the tw...

The HOPE Scale was introduced with initial validity evidence at the 2009 AERA conference. Based on these results a new validity study was conducted on revisions made to the Scale. Items were added and the HOPE Scale was completed by a new sample of 71 teachers on their respective 1700 students. Using these data, the HOPE Scale was evaluated using confirmatory factor analysis and multi-group CFA...

OBJECTIVE The objective was to determine whether the School Version of the Assessment of Motor and Process Skills (School AMPS) is valid when used to evaluate students in different world regions. METHOD Participants were 984 students, ages 3-13 yr, from North America, Australia and New Zealand, United Kingdom, and the Nordic countries, matched for age and diagnoses. We used FACETS many-facete...

The Conditional Reasoning Test for Aggression (CRT-A; James et al., 2005) is based on the ideas that aggressive individuals use motive-based cognitive biases to see their behavior as reasonable and that those biases can be measured with specially designed inductive reasoning tasks. The test has shown promising psychometric characteristics for U. S. samples but has not been validated in other cu...

BACKGROUND Four-factor structure of the two 8-item short forms of Child Perceptions Questionnaire CPQ11-14 (RSF:8 and ISF:8) has been confirmed. However, the sum scores are typically reported in practice as a proxy of Oral health-related Quality of Life (OHRQoL), which implied a unidimensional structure. This study first assessed the unidimensionality of 8-item short forms of CPQ11-14. Item res...
