A comparison between a visual analogue scale and a four point scale as measures of conscious experience of motion

Can participants make use of the large number of response alternatives of visual analogue scales (VAS) when reporting their subjective experience of motion? In a new paradigm, participants adjusted a comparison according to random dot kinematograms with the direction of motion varying between 0° and 360°. After each discrimination response, they reported how clearly they experienced the global motion either using a VAS or a discrete scale with four scale steps. We observed that both scales were internally consistent and were used gradually. The visual analogue scale was more efficient in predicting discrimination error but this effect was mediated by longer report times and was no longer observed when the VAS was discretized into four bins. These observations are consistent with the interpretation that VAS and discrete scales are associated with a comparable degree of metacognitive sensitivity, although the VAS provides a greater amount of information.     

Does the courage measure really measure courage? A theoretical and empirical evaluation

Courage has seen an explosion of research in all branches of psychology, and the most popular measure is Norton and Weiss’s the courage measure (CM). Despite widespread use, limited investigations into its psychometric properties and validity have been performed. To ensure the strength of findings drawn from the scale, the current study performs a theoretical, psychometric, and empirical analysis of the CM. The results demonstrate that the CM has theoretical concerns stemming from the operational definition of courage used during its creation, and may not actually measure courage. Also, the CM was shown to consist of two dimensions separated by regular and reverse coding. Next, the scale demonstrated slight concerns with method effects, and its construct validity was analyzed. Together, the results demonstrate that the CM would benefit from the removal of reverse coded items, and may actually gage persistence despite fear rather than courage.     

Individual Differences in Situation Awareness: Validation of the Situationism Scale

This article concerns the construct of lay situationism—an individual’s belief in the importance of a behavior’s context. Study 1 identified a 13-item Situationism Scale, which demonstrated good reliability and validity. In particular, higher situationism was associated with greater situation-control (strategies to manipulate the environment in order to avoid temptation). Subsequent laboratory studies indicated that people higher on the situationism subscales used greater situation-control by sitting farther from junk food (Study 2) and choosing to drink non-alcoholic beverages before a cognitive task (Study 3). Overall, findings provide preliminary support for the psychometric validity and predictive utility of the Situationism Scale and offer this individual difference construct as a means to expand self-regulation theory.     

The Recaptured Scale Technique: A Method for Testing the Structural Robustness of Personality Scales

Tellegen and Waller advocated a complex and time-consuming scale construction method that they called “exploratory test construction.” Scales that are constructed by this method—such as the Multidimensional Personality Questionnaire (MPQ)—are presumed to be more “psychologically coherent” and “robust” than scales constructed by other means. Using a novel procedure that we call the “recaptured scale technique,” we tested this conjecture by conducting a megafactor analysis on data from the 411 adult participants of the Minnesota Study of Twins Reared Apart who completed the MPQ, the MMPI, and the CPI. We extracted and obliquely rotated 21 factors from a matrix of gender-corrected tetrachoric correlations for the 1,102 nonredundant items of the three omnibus inventories. Robustness of the 11 MPQ scales was assessed by the degree to which these factors recaptured the MPQ item groupings. Our results showed that nine factors were clearly recognizable as MPQ scales and two additional factors represented a bifurcation of an MPQ scale. A higher-order factor analysis of all 21 factor scales yielded five factors that clearly resembled the Big Five. Our results provide strong support for (a) the method of exploratory test construction, (b) the structural robustness of most MPQ scales, and (c) the utility of the recaptured scale technique.     

The exploratory and confirmatory factor analyses of two subjective career success instruments

This study investigated the psychometric properties of two subjective career success instruments within the South African context: Perceived Career Success (PCSS: Gattiker &; Larwood, 1986 Gattiker, U. E., &; Larwood, L. (1986). Subjective career success: A study of managers and support personnel. Journal of Business and Psychology, 1(2), 78–94. http://dx.doi.org/10.1007/BF01018805[Crossref] , [Google Scholar]) and Life Success Measures Scale (LSMS: Parker &; Chusmir, 1992 Parker, B., &; Chusmir, L. H. (1992). Development and validation of a life-success measures scale. Psychological Reports, 70(2), 627–637. http://dx.doi.org/10.2466/pr0.1992.70.2.627[Crossref], [Web of Science ®] , [Google Scholar]). Data were collected via a convenient sample of 708 South African Police Services (SAPS) personnel (females = 36.8%; Sotho language = 62.50%). Exploratory factor analysis (EFA) was conducted on both instruments, followed by confirmatory factor analyses (CFA). Both instruments showed acceptable construct validity and reliability of scores.     

Developing the Impulsive Driver Behavior Scale

The aim of the present study is to develop a driving context specific impulsivity scale. First, a qualitative study was conducted by interviewing 20 individual drivers to develop the scale items based on the definitions of the basic impulsivity dimensions in the literature. Then, a quantitative study with a total of 506 individual drivers to examine the psychometric qualities of the newly developed Impulsive Driver Behavior Scale. In addition, the variance in driver behaviors, namely violations, errors, lapses and positive driver behaviors measured by the Driver Behavior Questionnaire (DBQ; Reason, Manstead, Stradling, Baxter, & Campbell, 1990) explained by the general impulsivity scales in the literature and the newly developed scale were compared. In all the comparisons, Impulsive Driver Behavior Scale explained higher amount of variance than the general impulsivity scales. Finally, it was found that the newly developed driving context specific impulsivity scale had incremental validity over the general impulsivity scales in predicting driver behaviors.     

Developing a Validity Argument Through Abductive Reasoning with an Empirical Demonstration of the Latent Class Analysis

This article proposes and demonstrates a methodology for test score validation through abductive reasoning. It describes how abductive reasoning can be utilized in support of the claims made about test score validity. This methodology is demonstrated with a real data example of the Canadian English Language Proficiency Index Program (CELPIP)-General test—a program assessing functional English language ability in the community and workplace. Abductive reasoning seeks the enabling conditions through which a claim about a person's ability makes sense. For example, it makes sense that a person has strong functional language proficiency if he or she has been regularly using English to write emails and meet with colleagues at work. A valid test score should be affected by the extent of a person's engagement with such enabling conditions. Empirical evidence that warrants such an abductively reasoned claim is illustrated through a latent class analysis within a structural equation model. Evidence is examined to investigate whether certain classes of test takers who have been differentially engaging in the enabling conditions do, in fact, predict a person's CELPIP-General performance. The steps of the methodology are summarized in the closing section.     

The classmates social isolation questionnaire (CSIQ): An initial validation

Social Isolation means having a lack of social contacts. This study reports a first validation of a brief self-report measure, the Classmates Social Isolation Questionnaire (CSIQ). The CSIQ is a questionnaire for children which assesses social isolation from classmates within the classroom as well as outside school. Data was based on a nationally representative sample of 26,670 Italian fifth grade students. Through exploratory and confirmatory factor analyses the bidimensional structure of the scale was established. The CSIQ showed measurement invariance both across gender and across groups with different immigrant backgrounds.Various tests of criterion validity had positive results and the CSIQ appears to be a valid and time-efficient instrument that can make a contribution to the study of social isolation and correlated factors.
