Studied the role of olfactory processes within the theory of fluid and crystallized intelligence by testing 107 Australian college students with a battery of psychometric and olfactory tests. Results indicate the likely existence of an olfactory memory ability that is structurally independent of established higher-order abilities and not related…

Most, if not all, of the studies of subtypes of children with language impairments have been conducted with English-speaking children. The possibility and validity of identified subtypes for non-English clinical populations are, as yet, unknown. This study was designed to provide cross-linguistic evidence of language subtypes. A broad battery of…

The relations between normative beliefs about different forms of aggression and corresponding aggressive behaviors were investigated in 2 studies of adolescents. In Study 1, we revised an instrument designed to assess normative beliefs about aggression to include beliefs about the acceptability of relational aggression, and we examined the…

The reliability and validity of 4 approaches to the assessment of children and adolescents with learning disabilities (LD) are reviewed, including models based on (a) aptitude-achievement discrepancies, (b) low achievement, (c) intra-individual differences, and (d) response to intervention (RTI). We identify serious psychometric problems that…

Objective: This study reports on the psychometric properties of a brief, self-administered screening questionnaire, the Columbia SuicideScreen[R] (CSS), intended to identify high school students at risk for suicide. Method: Seventeen hundred twenty-nine 9th- to 12th-grade students completed the CSS and Beck Depression Inventory during school hours…

Although RC(M)-association models have become a generally useful tool for the analysis of cross-classified data, the graphical representation resulting from such an analysis can at times be misleading. The relationships present between row category points and column category points cannot be interpreted by inter point distances but only through…

The asymptotic standard deviation (SD) of the alpha coefficient with standardized variables is derived under normality. The research shows that the SD of the standardized alpha coefficient becomes smaller as the number of examinees and/or items increase. Furthermore, this research shows that the degree of the dependence of the SD on the number of…

Multiple-choice items are a mainstay of achievement testing. The need to adequately cover the content domain to certify achievement proficiency by producing meaningful precise scores requires many high-quality items. More 3-option items can be administered than 4- or 5-option items per testing time while improving content coverage, without…

The 160-item short form of the Personality Assessment Inventory (PAI) was developed for situations in which respondents complete only the 1st half of the test. The present study evaluates the adequacy and comparability of the full and short forms of the PAI in terms of a wide range of psychometric characteristics. In all, 421 participants…

The psychometric properties of the Achievement Goal Questionnaire (AGQ), when modified for a general academic context, were examined. Previous research has found evidence of a four-factor structure of achievement goal orientation when this measure was used in a course-specific context. This study is an important addition to goal orientation…

The Job Descriptive Index family of job attitude measures includes the Job in General (JIG) scale, a measure of global satisfaction with one's job. The scale was originally developed and validated by Ironson, Smith, Brannick, Gibson, and Paul. Following structured scale reduction procedures developed by Stanton, Sinar, Balzer, and Smith, the…

Ensuring construct comparability is a prerequisite for testing cross-group differences, yet this assumption is rarely tested in mentoring research. More studies testing for factorial invariance are needed for the construct validation of mentoring. Multiple group confirmatory factor analyses (CFAs) were used to investigate the factorial stability…

The issue of stress associated with higher education and its impact on markers of student health is explored in three experiments looking at blood pressure levels in college students. All participants were full-time undergraduate students of psychology. In Experiment 1, academic fear of failure, assessed using psychometric testing, was found to be…
