Quantifying the Strength of General Factors in Psychopathology: A Comparison of CFA with Maximum Likelihood Estimation,BSEM, and ESEM/EFA Bifactor Approaches

Whether or not importance should be placed on an all-encompassing general factor of psychopathology (or p factor) in classifying, researching, diagnosing, and treating psychiatric disorders depends (among other issues) on the extent to which comorbidity is symptom-general rather than staying largely within the confines of narrower transdiagnostic factors such as internalizing and externalizing. In this study, we compared three methods of estimating p factor strength. We compared omega hierarchical and explained common variance calculated from confirmatory factor analysis (CFA) bifactor models with maximum likelihood (ML) estimation, from exploratory structural equation modeling/exploratory factor analysis models with a bifactor rotation, and from Bayesian structural equation modeling (BSEM) bifactor models. Our simulation results suggested that BSEM with small variance priors on secondary loadings might be the preferred option. However, CFA with ML also performed well provided secondary loadings were modeled. We provide two empirical examples of applying the three methodologies using a normative sample of youth (z-proso, n = 1,286) and a university counseling sample (n = 359).     

The Five Factor Mindfulness Questionnaire in Norway

The aim of this study was to adapt the Five Factor Mindfulness Questionnaire (FFMQ) for use in Norway. Three studies involving three different samples of university students (mean age 22 years, total N = 792) were conducted. Confirmatory factor analyses showed that a five factor structure provided an acceptable fit to the data. All five factors loaded significantly on the overall mindfulness factor. As expected, correlations between the FFMQ total scores and subscales were positive and significant, ranging from 0.45 to 0.65. Correlations between FFMQ total/subscales and Mindful Attention Awareness Scale (MAAS) were significant and negative (since low scores on the MAAS indicate high mindfulness), ranging from r = ?0.17 to ?0.69. The Norwegian FFMQ total score was inversely correlated with all indicators of psychological health: neuroticism (r = ?0.61), ruminative tendencies (r = ?0.41), self‐related negative thinking (r = ?0.40), emotion regulation difficulties (r = ?0.66) and depression (r = ?0.46 to r = ?0.65). In contrast to the other FFMQ subscales, the FFMQ Observe subscale did not have a positive relation to psychological health in our mostly non‐meditating sample. However, being able to non‐judgmentally observe one's inner life and environment is a part of the mindfulness construct that might emerge more clearly with more mindfulness training. We conclude that the Norwegian FFMQ has acceptable psychometric properties and can be recommended for use in Norway, especially in studies seeking to differentiate between different aspects of mindfulness and how these may change over time.     

The ontogeny of relational memory and pattern separation

Episodic memory relies on memory for the relations among multiple elements of an event and the ability to discriminate among similar elements of episodes. The latter phenomenon, termed pattern separation, has been studied mainly in young and older adults with relatively little research on children. Building on prior work with young children, we created an engaging computer‐administered relational memory task assessing what‐where relations. We also modified the Mnemonic Similarity Task used to assess pattern discrimination in young and older adults for use with preschool children. Results showed that 4‐year‐olds performed significantly worse than 6‐year‐olds and adults on both tasks, whereas 6‐year‐olds and adults performed comparably, even though there were no ceiling effects. However, performance on the two tasks did not correlate, suggesting that two distinct mnemonic processes with different developmental trajectories may contribute to age‐related changes in episodic memory.     

Individual differences in white matter microstructure predict semantic control

In everyday conversation, we make many rapid choices between competing concepts and words in order to convey our intent. This process is termed semantic control, and it is thought to rely on information transmission between a distributed semantic store in the temporal lobes and a more discrete region, optimized for retrieval and selection, in the left inferior frontal gyrus. Here, we used diffusion tensor imaging in a group of neurologically normal young adults to investigate the relationship between semantic control and white matter tracts that have been implicated in semantic memory retrieval. Participants completed a verb generation task that taps semantic control (Snyder & Munakata, 2008; Snyder et al., 2010) and underwent a diffusion imaging scan. Deterministic tractography was performed to compute indices representing the microstructural properties of the inferior fronto-occipital fasciculus (IFOF), the uncinate fasciculus (UF), and the inferior longitudinal fasciculus (ILF). Microstructural measures of the UF failed to predict semantic control performance. However, there was a significant relationship between microstructure of the left IFOF and ILF and individual differences in semantic control. Our findings support the view put forth by Duffau (2013) that the IFOF is a key structural pathway in semantic retrieval.     

Payoffs for layoffs? An examination of CEO relative pay and firm performance surrounding layoff announcements

In this study, we theorize that chief executive officers’ (CEOs’) peer pay comparisons influence their decisions to engage in layoffs, and we consider the conditions under which layoffs deliver “payoffs” in the form of increases in subsequent CEO relative pay. Our results indicate that CEOs receiving compensation below their peers are significantly more likely to announce layoffs in the subsequent year, relative to those receiving compensation above their peers. Further, we find that the relationship between layoffs and subsequent changes in CEO relative pay depends on postlayoff changes in firm performance, with CEOs in firms with the largest performance gains receiving the largest increases in relative pay. We also show that our results are robust to an alternative operationalization of CEO relative pay. We provide evidence that external social comparisons may have predictable consequences for both CEOs’ propensities to engage in particular strategic actions and future changes in CEOs’ relative pay.     

Dimensional Latent Structure of Early Disruptive Behavior Disorders: A Taxometric Analysis in Preschoolers

Although disruptive behavior disorders (DBDs) are used as a distinct categorical diagnosis in clinical practice, they have repeatedly been described as having a dimensional structure in taxometric analyses. In the current study the authors analyzed the latent status of disruptive behaviors (DB) in a large sample (N?=?2,808) of German preschool children (2–6 years old, mean age 53.7 months, SD?=?13.5, 48.4% girls). The Eyberg Child Behavior Inventory (ECBI) as well as the Strengths and Difficulties Questionnaire (SDQ) were used to compile indicators of the DB core dimensions (Temper Loss, Aggression, Noncompliance, and Low Concern for others). Three widely used taxometric methods (a) MAXEIG, (b) MAMBAC, and (c) L-Mode were applied. Simulation data were created to evaluate the Comparison Curve Fit Index values (CCFIs), which were below 0.45, supporting a dimensional solution. Hence, in the current study the latent structure of DB in preschoolers encompassed differences in degree rather than kind. Researchers and practitioners should be mindful of the dimensional latent status of DB in theory building, assessment, classification, and labeling.     

Work Stress and Comfort in University Faculty: Do Gender and Academic Field Matter?

University faculty face stressors, including multiple roles, institutional pressures, and varying student demands, which may differ by gender and across fields. Using the questionnaire variant of a convergent mixed-methods design, we examined whether self-reported work stress and comfort differed by gender and academic field gender stereotype in participants from two universities. Results showed that female faculty reported more quantitative role overload, qualitative role overload, and career development stress than male faculty regardless of field. Qualitative themes centered on institutional barriers and unique pressures for women, although these experiences varied by field. Implications, limitations, and future research for employment counselors are explored.     

Ethical Leadership and Unethical Pro-Organisational Behaviour: The Mediating Mechanism of Reflective Moral Attentiveness

This study examines the mediating effects of reflective moral attentiveness on the relationship between ethical leadership and subordinates’ unethical pro-organisational behaviour (UPB). Based on two-wave survey data obtained from 233 employees in 60 teams from Chinese government agencies, we found that ethical leadership was positively related to reflective moral attentiveness. In addition, we found that reflective moral attentiveness mediated the relationship between ethical leadership and UPB, such that ethical leadership negatively influenced subordinates’ unethical pro-organisational behaviour through enhancing reflective moral attentiveness.
