Item grouping and item randomization in personality measurement

This paper describes a study examining the impact of item order in personality measurement on reliability, measurement equivalence and scale-level correlations. A large sample of university students completed one of three forms of the International Personality Item Pool version of the Big Five personality inventory: items sorted at random, items sorted by factor, and items cycled through factors. Results showed that the underlying measurement model and the internal consistency of the IPIP-Big Five scale was unaffected by differences in item order. Also, most of the scale-level correlations among factors were not significantly different across forms. Implications for the administration of tests and interpretation of test scores are discussed, and future research directions are offered.     

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.     

Toward a Positive Military Psychology

The present study used an informant method of psychiatric assessment to evaluate Saddam Hussein, and these results were compared to a posthumous assessment of Adolf Hitler. Eleven Iraqi adults who lived under Hussein's influence for a median of 24 years completed the Coolidge Axis II Inventory, a measure of 14 personality disorders. The mean consensus among the 11 raters was r = .57. It revealed that Hussein probably reached diagnostic threshold for the sadistic (T score M = 81.0), paranoid (T score M = 79.3), antisocial (T score M = 77.4), and narcissistic (T score M = 74.2) personality disorders. The correlation between the consensus profile for Hussein and a consensus profile of 5 Hitler experts was r = .79, indicating a very strong similarity between the two profiles. It was concluded that Saddam Hussein had many of the same personality disorders or their features as Adolf Hitler, although sadistic features were stronger in Hussein than Hitler. It appeared that a “Big Four” personality disorders constellation emerged for these two dictators, and they were sadistic, antisocial, paranoid, and narcissistic. It was also found that Hussein might have had some traits or features of paranoid schizophrenia. Implications for diplomacy and negotiations with persons with similar personality profiles are proffered.     

Treating PTSD in active duty service members using cognitive processing therapy or prolonged exposure therapy: Examining everyday practice at a military outpatient clinic

The Institute of Medicine has stressed the need for evaluations of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD) among active duty service members (AD) using a variety of evaluation approaches (Institute of Medicine, 2012). The current study examined the clinical files of 134 service members who completed treatment for PTSD using either prolonged exposure (PE) or cognitive processing therapy at an outpatient clinic. At the completion of each session, therapists made a clinical rating as to whether or not the session was protocol adherent. The total number of treatment sessions and the proportion of sessions rated as being protocol adherent were calculated. Multi-level models estimated the change in patient PTSD and other psychological symptoms over time as a function of clinician-rated protocol adherence and total number of sessions. Approximately 65% of clinic encounters were rated by therapists as being protocol adherent. Significant reductions in PTSD and psychological symptoms were associated with protocol adherence, and this was particularly true for patients who began treatment above clinical thresholds for both PTSD and other psychological symptoms. However, as the number of sessions increased, the impact of protocol adherence was attenuated. Patient characteristics, including gender, ethnicity, and co-morbidity for other psychiatric disorders were not related to symptom change trajectories over time. These findings suggest that protocol adherence and efficiency in delivery of EBTs for the treatment of PTSD with AD is critical.     

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.     

More Than a Sex Machine: Accomplishing Masculinity Among Chinese Male Sex Workers in the Hong Kong Sex Industry

Situated in the masculinity and deviance literature, this article examines a “deviant” masculinity, that of the male sex worker, and presents the ways men who engage in sex work cope with the job. Based on in-depth interviews of Chinese male sex workers (n = 18) in the Hong Kong sex industry, I argue that the stigma management techniques these men employ are simultaneously gender strategies they use to accomplish masculinity. It is through this process that they negotiate a masculine identity within the hierarchy of masculinities in order to become “respectable” and “responsible” Chinese men.
