The Multitasking Preference Inventory: Toward an Improved Measure of Individual Differences in Polychronicity

This article describes the initial development of a new measure of individual polychronicity, a construct indicating a preference for multitasking as opposed to performing only one task at a time. Following a brief review of past definitional issues, a revised definition is offered and a new measure of polychronicity—the Multitasking Preference Inventory (MPI)—is created based on this definition. Three studies describe the creation, pilot testing, and psychometric refinement of an initial pool of items (Study 1); a convergent and discriminant validity analysis (Study 2); and initial findings with respect to the criterion-related validity of scores on the MPI (Study 3). Together, these findings provide preliminary evidence for the reliability of scores on the MPI and the validity of the MPI in predicting variables relevant to multitasking.     

The Team Personality–Team Performance Relationship Revisited: The Impact of Criterion Choice,Pattern of Workflow,and Method of Aggregation

Using meta-analytic evidence, this study tested trait- and task-based theoretical approaches to team personality management, using both team behaviors and team outcomes as criteria. Trait theories state that maximization of the team trait is harmful for Extroversion (complementary team fit) but beneficial for Conscientiousness, Agreeableness, and Emotional Stability (supplementary fit). Task-based theories state that tasks with few work exchanges are best reflected by mean trait scores, whereas tasks with frequent work exchanges are best represented by other types of scores (e.g., minimum score). Correlations between different aggregations of team personality and team performance were coded, as well as the study criterion choice and the pattern of workflow (as moderators). Partial support for both trait and task theories were found. Team Conscientiousness and Agreeableness provided supplementary fit primarily with team behaviors, but there was mixed evidence that Extroversion provided complementary fit. Furthermore, minimum and variance measures of the team trait related to team performance in tasks with frequent work exchanges, but not in tasks with few work exchanges. Results suggest several limitations with existing measurement methods, which are discussed.     

Normative Scoring of Multidimensional Pairwise Preference Personality Scales Using IRT: Empirical Comparisons With Other Formats

In this article, we offer some suggestions as to why tetrads and pentads have become the dominant formats for administering multidimensional forced choice (MFC) items but, in turn, raise questions regarding the underlying psychometric model and means of addressing item quality and scoring accuracy. We then focus our attention on multidimensional pairwise preference (MDPP) items and present an item response theory–based approach to constructing and modeling MDPP responses directly, assessing information at the item and scale levels, and a way of computing standard errors for trait scores and estimating scale reliability. To demonstrate the viability of this method for applied use, we show that the correspondence between MDPP scores derived from direct modeling with those obtained using single statement and unidimensional pairwise preference measures administered in a laboratory setting. Trait score correlations and criterion related validities are compared across testing formats and rating sources (i.e., self and other), and the usefulness of our model-based approach is further demonstrated by some illustrative results involving computerized adaptive tests (CAT).     

Calibrating Situation Awareness and Confidence Within a Multinational Coalition Operation

In the present article the calibration of situation awareness and confidence within a multinational coalition was examined. The results revealed differential levels of situational awareness and calibration across the members of the coalition. These findings are discussed in terms of both linguistic and cultural differences within the coalition and the potential implications that poor calibration can have for decision-making and overall team performance.     

Getting What the Occupation Gives: Exploring Multilevel Links Between Work Design and Occupational Values

The history of work design research is voluminous and compelling. Thousands of studies have demonstrated the wide‐reaching and powerful impact the design of work can have on a host of meaningful outcomes. Yet, absent in much of this research is an explicit consideration of the context within which work is performed and how this context might impact work design. Drawing from the theory of work adjustment, we describe the different ways in which occupations are linked to work design. In a sample of 805 individuals from 230 occupations, our multilevel examinations show the occupational‐level values of achievement, independence, altruism, status, and comfort are related to a variety of work characteristics. In addition, we found that work characteristics are key mechanisms through which these occupational values affect individual‐level job satisfaction. Implications of these results for work design theory and practice are discussed.     

Descriptive and Predictive Analyses of Industrial Buyers' Use of Online Information for Purchasing

The impact of demographic differences between sales reps and their managers is explored using data gathered from 340 manager-rep dyads. Education and gender differences between sales reps and managers, but not age differences, are shown to affect sales reps' role stress, organizational attachment, and perceptions of opportunities for advancement, as well as managers' ratings of the reps' performance. Study results support findings of previous research addressing relational demography and the similarity-attraction paradigm. The chief divergence of this study is that it depicts the role of frequency of contact between sales rep and manager in the link between demographic similarity and several outcome variables.     

Collective contributions to career efficacy in adolescents: A cross-cultural study

This study extended the concept of collective efficacy to supplement the variable of career self-efficacy to predict vocational exploration and commitment among adolescents. We developed a Collective Contributions to Career Efficacy Scale (CCCE) to measure adolescents' perceived contributions from parents, teachers, and peers on their career-related matters. A total of 1175 high school students from Hong Kong, Shanghai and Michigan participated in the study by completing the CCCE, the Career Decision Self-Efficacy Scale (CDSE-SF), and the Vocational Exploration and Commitment Subscale (VEC). Using multi-sample Structural Equation Modeling, we found that the effect of CCCE on VEC was mediated by CDSE. Although we found cultural differences in the overall level of the vocational measures among the Hong Kong, Shanghai, and American students, the mediation model was confirmed in all three groups of students.     

Self-evaluation and self-perception: The role of attention in the experience of anxiety

Abstract

Self-awareness promotes the experience of anxiety in two ways. It does so directly, by enhancing awareness of the emotional state itself, and by initiating the self-evaluation process that is necessary for anxiety to occur. It also does so indirectly, by constraining some behaviors and inhibiting others. In particular, it increases accuracy of self-perception, and, in so doing, retards the process of self-delusion. This is important, because the latter process has been shown to have a salutary effect on mental health, acting as a buffer against dysphoric states such as depression and anxiety.     

THE EFFECT OF REPERTORY GRID SCALE SIZE AND RATING DIRECTION ON STRUCTURAL MEASURES OF DIFFERENTIATION

Previous work by Soldz and Soldz (1989) indicated that variations in repertory grid features can have a significant impact on the interpretation of the Landfield Functionally Independent Construction Score (FIC), which is a measure of cognitive differentiation. In this study, we showed that four different grid measures (FIC, Total number of zeroes, and the number of midpoint ratings used to indicate either equality or nonapplicability) can be effected by the use of a certain scale size (3-point, 7-point, 13-point), and by the direction of administration (completing the grid in a downwards direction vs. an across-wise direction). In addition, correlations between the number of zero ratings and the total FIC scores for each of the different scale sizes and directions showed evidence to support and to qualify previous work conducted by Soldz and Soldz (1989). In general, high positive correlations were found, suggesting the impact of zero ratings on FIC scores. But the magnitude of the correlations between the zero ratings and the total FIC scores varied as a function of the scale size, the direction of administration, and the meaning of the zero rating (neutrality vs. nonapplicability), raising theoretical, as well as procedural, considerations for future repertory grid research.
