Some relationships between the information function of IRT and the signal/noise ratio and reliability coefficient of classical test theory

It is shown that IRTs information function for an item is functionally related to local versions of classical test theories' signal/noise ratio and reliability coefficient.     

An IRT assessment of Rotter's I-E scale: a new approach and some considerations

This study assessed the functioning and measurement properties of Rotter's Locus of Control Scale in its Spanish version by using a new approach based on Item Response Theory. Our procedure allows us: (a) to detect the impact of response biases (acquiescence and social desirability); (b) to evaluate clearly the test dimensionality and structure; (c) to evaluate and understand the causes of some items' inefficiency; and (d) to increase measurement precision. Globally, the results do not contradict those obtained in previous research, but allow some of the criticisms the scale had received to be qualified. Some recommendations for use are proposed.     

Coping through emotional approach: scale construction and validation

Four studies demonstrate the psychometric adequacy and validity of scales designed to assess coping through emotional approach. In separate undergraduate samples, exploratory and confirmatory factor analyses of dispositional (Study 1) and situational (Study 3) coping item sets yielded 2 distinct emotional approach coping factors: emotional processing (i.e., active attempts to acknowledge and understand emotions) and emotional expression. The 2 scales yielded high internal consistency and test-retest reliability, as well as convergent and discriminant validity. A study (Study 2) of young adults and their parents established the scales' interjudge reliabilities. Longitudinal (Study 3) and experimental (Study 4) research supported the predictive validity of the emotional approach coping scales with regard to adjustment to stressful encounters. Findings highlight the utility of functionalist theories of emotion as applied to coping theory.     

Development and validation of the job crafting scale

We developed and validated a scale to measure job crafting behavior in three separate studies conducted in The Netherlands (total N = 1181). Job crafting is defined as the self-initiated changes that employees make in their own job demands and job resources to attain and/or optimize their personal (work) goals. In Study 1 and 2 the Dutch job crafting scale (JCS) was developed and tested for its factor structure, reliability, and convergent validity. The criterion validity of the JCS was examined in Study 3. The results indicated that there are four independent job crafting dimensions, namely increasing social job resources, increasing structural job resources, increasing challenging job demands, and decreasing hindering job demands. These dimensions could be reliably measured with 21 items. The JCS shows convergent validity when correlated with the active constructs proactive personality (+), personal initiative (+), and the inactive construct cynicism (?). In addition, results indicated that self-reports of job crafting correlated positively with colleague-ratings of work engagement, employability, and performance — thus supporting the criterion validity of the JCS. Finally, self-rated job crafting behaviors correlated positively with peer-rated job crafting behaviors.     

Development and validation of the statistical anxiety scale

Nowadays, there is a great deal of evidence to suggest that personality variables can play an important role in the prediction of academic performance. However, many authors have mentioned that the differences in the prediction power of broad and narrow personality measures must be taken into account. We develop and validate a scale to assess the anxiety encountered when taking a statistics course. We designed the inventory as a set of 24 positive sentences that measure three subscales: Examination Anxiety , Asking for Help Anxiety and Interpretation Anxiety . In addition, as the three dimensions correlated with each other, they were considered related subscales from an overall scale, which measures statistical anxiety. Results show that these specific measures of anxiety about statistics have a significant relationship with academic performance in statistics whereas broader measures of anxiety or neuroticism do not.     

Development and validation of the childhood narcissism scale

In this article, we describe the development and validation of a short (10 item) but comprehensive self-report measure of childhood narcissism. The Childhood Narcissism Scale (CNS) is a 1-dimensional measure of stable individual differences in childhood narcissism with strong internal consistency reliability (Studies 1-4). The CNS is virtually unrelated to conventional measures of self-esteem but is positively related to self-appraised superiority, social evaluative concern and self-esteem contingency, agentic interpersonal goals, and emotional extremity (Study 5). Furthermore, the CNS is negatively related to empathic concern and positively related to aggression following ego threat (Study 6). These results suggest that childhood narcissism has similar psychological and interpersonal correlates as adult narcissism. The CNS provides researchers a convenient tool for measuring narcissism in children and young adolescents with strong preliminary psychometric characteristics.     

Development and validation of the shy bladder scale

Paruresis, characterized by the difficulty or inability to urinate in a variety of social contexts, is a scientifically under-studied phenomenon. One reason for this state of affairs is the paucity of reliable and valid measures for assessing this problem. The present article attempted to address this limitation by investigating the psychometric properties and validity of a new measure of paruresis: the Shy Bladder Scale (SBS). In two undergraduate samples, the SBS demonstrated excellent internal consistency and a stable factor structure assessing difficulty urinating in public, impairment and distress, and paruresis-related fear of negative evaluation. Undergraduate students evidenced very low levels of paruresis-related concerns. In contrast, SBS scores were markedly elevated among individuals recruited from an online support network who appeared to meet diagnostic criteria for paruresis-specific social phobia. Our findings highlight the SBS's potential utility as a measure of paruresis in clinical and research contexts.     

Social Cynicism and Job Satisfaction: A Longitudinal Analysis

Social cynicism, a negative view about people and social institutions, was found to show a negative correlation with job satisfaction across societies. A preliminary study in Hong Kong showed that social cynicism and job satisfaction correlated negatively across individuals as well. To confirm the causal effect of social cynicism on job satisfaction, a longitudinal study in Shanghai, China, with three waves of surveys, was conducted. Results showed that social cynicism correlated negatively with job satisfaction measured concurrently, and was predictive of job satisfaction measured subsequently. Consistent with the buffering hypothesis, perceived well‐being was a significant moderator in that the negative relationship between social cynicism and job satisfaction was significant only when perceived well‐being was low. On s'est aperçu que le cynisme social (une vision négative des gens et des institutions sociales) entretenait une corrélation négative avec la satisfaction professionnelle quelle que soit la société. Une étude préliminaire à Hong‐Kong a montré que le cynisme social et la satisfaction professionnelle présentaient également une corrélation négative au niveau de l'individu. Dans le but de confirmer le statut causal du cynisme social sur la satisfaction professionnelle, on a mené une étude longitudinale en Chine, à Shanghai, avec trois enquêtes successives. Les résultats montrent que le cynisme social est négativement reliéà la satisfaction professionnelle mesurée au même moment et prédit la satisfaction professionnelle mesurée ultérieurement. En accord avec l'hypothèse portant sur la résistance aux aléas de l'existence, le bien‐être perçu est un modérateur actif dans la mesure où la relation négative entre le cynisme social et la satisfaction professionnelle n'est significative que lorsque le bien‐être perçu est médiocre.     

Development and validation of the coach's task presentation scale: A quantitative self-report instrument

ObjectiveA major concern for coaches is the transmission of effective information in the moments before sport practice, when they communicate to players what they are supposed to do and how (Rink, 1994). The present study's main objective was to cover a gap in the sport psychology measurement field and to develop and validate a quantitative self-report instrument to measure the effectiveness of coaches' task presentation for athletes. The resulting instrument was the Escala de Presentación de las Tareas por Parte del Entrenador (EPTE) [Coach's Task Presentation Scale].DesignThe two studies developed to validate the EPTE used a cross-sectional research design.MethodParticipants in Study 1 included 830 college athletes aged between 18 and 27, who completed the EPTE. Participants in Study 2 included 677 college athletes aged between 17 and 29, who completed the EPTE and other questionnaires measuring coach's interpersonal style (autonomy support and controlling style) and basic psychological needs satisfaction/thwarting. Study 1 comprised translation, item formulation and examination of the reliability and factorial structure of the EPTE. Study 2 provided evidence of factorial validity and evidence of validity based on relationships with other variables in the context of the Self Determination Theory (Deci & Ryan, 2000).ResultsThe results of reliability analysis and the different sources of validity provided, demonstrated the instrument's adequacy in terms of psychometric properties.ConclusionsThe EPTE is a valid, reliable scale that can be used to measure the effectiveness of task presentation by coaches, according to the perception of athletes.     

Bayesian inference and the classical test theory model: Reliability and true scores

A general one-way analysis of variance components with unequal replication numbers is used to provide unbiased estimates of the true and error score variance of classical test theory. The inadequacy of the ANOVA theory is noted and the foundations for a Bayesian approach are detailed. The choice of prior distribution is discussed and a justification for the Tiao-Tan prior is found in the particular context of the “n-split” technique. The posterior distributions of reliability, error score variance, observed score variance and true score variance are presented with some extensions of the original work of Tiao and Tan. Special attention is given to simple approximations that are available in important cases and also to the problems that arise when the ANOVA estimate of true score variance is negative. Bayesian methods derived by Box and Tiao and by Lindley are studied numerically in relation to the problem of estimating true score. Each is found to be useful and the advantages and disadvantages of each are discussed and related to the classical test-theoretic methods. Finally, some general relationships between Bayesian inference and classical test theory are discussed.

Job Importance as a Moderator of the Relationship Between Job Satisfaction and Life Satisfaction

Moderated regression analyses are used to assess the degree to which indirect indicators of job importance moderate the relationship between job satisfaction and life satisfaction. The 1971 Quality of American Life Survey (N = 2,164) and the 1972-1973 Quality of Employment Survey (N = 1,496) provide two large nationwide probability sample data sets for these secondary analyses. It is hypothesized that the strength of the job satisfaction-life satisfaction relationship is positively related to job importance. Contrary to this hypothesis, respondents whose jobs were expected to be more important do not have substantially stronger job satisfaction-life satisfaction relationships than respondents whose jobs were expected to be less important. The zero-order job satisfaction–life satisfaction correlations in both samples are stronger than expected (r = .48 and r = .49). Discussion focuses on the conceptual implications of the failure to find substantial moderator effects. Locke's (1969) theory of the implicit role of importance in determining satisfaction is invoked to explain the obtained pattern of results.     

Development and validation of the situational self-awareness scale.

This article discusses the manipulation and measurement of levels of situational self-focus, which is generally labeled "self-awareness." A new scale was developed to quantify levels of public and private self-awareness. Five studies were conducted to assess the psychometric properties, reliability, and validity of the Situational Self-Awareness Scale (SSAS). The SSAS was found to have a reliable factor structure, to detect differences in public and private self-awareness produced by laboratory manipulations, and to be sensitive to changes in self-awareness within individuals over time and across situations. The SSAS can be used as a manipulation check of laboratory self-awareness manipulations and as a means of assessing naturally occurring fluctuations in public and private self-awareness in order to clarify the relation between self-awareness and other variables (e.g., mood and memory).     

Constructive Thought Strategies and Job Satisfaction: A Preliminary Examination

In order to examine the potential of constructive thought strategies for enhancing employee job satisfaction, an existing dispositional model of job satisfaction was expanded and tested. Structural equation modeling techniques indicated significant relationships among constructive thought strategies, dysfunctional thought processes, subjective well-being, and job satisfaction. In addition, two competing models were examined to test for the full or partial mediation of the effects of constructive thought strategies on job satisfaction. The implications of these findings for constructive thought strategy training interventions are discussed, along with directions for future research efforts.     

Dispositional Affect and Job Satisfaction: A Review and Theoretical Extension

Over the past 15 years, researchers have paid increasing attention to the dispositional source of job satisfaction. This research, though not without its controversies, has provided strong evidence that job satisfaction is, in part, dispositionally based. In this article we review past research on dispositional influences on job satisfaction. The two areas most in need of future research attention are (a) which trait(s) should be included in investigations of the dispositional source of job satisfaction and (b) elucidating the theoretical processes underlying the effect of dispositions on job satisfaction. In attempting to facilitate future research in these two areas, we first provide an integrative review of the personality and affective traits relevant to the dispositional source of job satisfaction. Second, we discuss a number of theoretical processes and mechanisms, drawn largely from personality psychology, which may further illuminate the dispositional source of job satisfaction. We pay particular attention to a model that seeks to unify the literature on affect and personality and discuss how applications of this model may lead to greater understanding of the personological basis of job satisfaction.     

Development and validation of Swedish classical and modern sexism scales

In two studies we develop and validate a Classical--overt or direct--and a Modern--covert or subtle--Sexism Scale concerning attitudes toward women, for a Swedish (Scandinavian) context. Further, we examine whether these two forms of prejudice are distinguishable. Confirmatory factor analyses showed that, although highly correlated, classical and modern sexism are distinguishable. The construct validations showed that men had higher means on modern and classical sexism scores than women, and that our scales were related to other constructs as expected. In a third study, we analyzed the knowledge and the content of cultural stereotypes about women. There were no differences in the knowledge of cultural stereotypes between men and women or between high- and low-sexist individuals. The findings are discussed in relation to previous international studies that examine people's modern and/or classical sexism.
