Employees High in Personal Intelligence Differ From Their Colleagues in Workplace Perceptions and Behavior

Personal intelligence (PI) involves the ability to recognize, reason, and use information about personality to understand oneself and other people. Employees in two studies (Ns = 394, 482) completed the Test of Personal Intelligence (TOPI; e.g., Mayer, Panter, & Caruso, 2017a) and assessments of workplace perception and behavior. Higher PI was associated with higher perceived workplace support and lower counterproductive work behavior. These relationships continued to hold after controlling for other key variables. The results indicate the TOPI, although still in research trials, shows promise as a screening device for selecting employees and targeting individuals for training.     

Parent–Child Informant Discrepancy is Associated with Poorer Treatment Outcome

In child clinical psychology, parent and child reports are typically used to make treatment decisions and determine the effectiveness of treatment. However, there are often moderate to large discrepancies between parent and child reports, and these discrepancies may reflect meaningful information about the parent, the child, and the parent–child relationship. Additionally, parent–child discrepancy may predict treatment outcome. This study examined parent–child discrepancy in a sample of 62 children (10.15±1.26 years old) with prominent social competence deficits and mixed diagnoses who were treated with a resilience-based, cognitive–behavioral group therapy program (the Resilience Builder Program) in a private clinical setting. Further analyses were conducted to investigate whether parent–child discrepancy related to treatment outcome. Consistent with the literature, prominent parent–child discrepancy was found across domains, with parents generally reporting more severe symptomatology. Treatment with the Resilience Builder Program resulted in significant improvement in parent report of multiple domains of functioning, including resilience, social skills, and emotion and behavior regulation. Importantly, larger parent–child discrepancy at the start of therapy was predictive of poorer overall treatment response. Given its impact on therapeutic effectiveness, these results suggest that parent–child disagreement regarding the child’s impairment at the onset of therapy is worthy of assessment prior to treatment, and may itself be a topic worthy of targeting in treatment.     

Causation and melanoma classification

In this article, I begin by giving a brief history of melanoma causation. I then discuss the current manner in which malignant melanoma is classified. In general, these systems of classification do not take account of the manner of tumour causation. Instead, they are based on phenomenological features of the tumour, such as size, spread, and morphology. I go on to suggest that misclassification of melanoma is a major problem in clinical practice. I therefore outline an alternative means of classifying these tumours based on causal factors. By analogy with similar systems that have recently emerged for other cancers, I suggest that this causal classification is likely to be both workable and helpful, even in the absence of a full causal-mechanistic understanding of the aetiology of the tumour.     

A biopsychosocial approach to liver transplant evaluation in two patients with Wilson's disease

Wilson's disease (WD) is characterized by hepatic, neurological, and/or psychiatric disturbances. In some cases, liver transplantation is indicated. Because psychologists and other health care workers play an increasing role in the evaluation of individuals presenting for transplant, an understanding of the heterogeneous phenotype of WD is important for mental health professionals working in medical settings. This article reviews two cases of patients with WD (one probable, one confirmed) presenting for liver transplantation and a biopsychosocial assessment approach is demonstrated. Patients are presented in terms of medical, psychiatric, and psychosocial history, neuropsychological examination results, and the subsequent indications for liver transplantation. Both patients exhibited neurocognitive and psychiatric symptoms. One patient was determined to be a marginally suitable candidate for transplantation, whereas the other was considered at high risk for negative outcome post-transplant. This article demonstrates the importance of considering phenotypic presentation, neurocognitive function, psychiatric status, and psychosocial circumstances in assessing transplant readiness in patients with WD. A comprehensive and integrative biopsychosocial assessment approach is appropriate for evaluating patients with WD presenting for liver transplantation.     

Determining the number of factors to retain in an exploratory factor analysis using comparison data of known factorial structure

Exploratory factor analysis (EFA) is used routinely in the development and validation of assessment instruments. One of the most significant challenges when one is performing EFA is determining how many factors to retain. Parallel analysis (PA) is an effective stopping rule that compares the eigenvalues of randomly generated data with those for the actual data. PA takes into account sampling error, and at present it is widely considered the best available method. We introduce a variant of PA that goes even further by reproducing the observed correlation matrix rather than generating random data. Comparison data (CD) with known factorial structure are first generated using 1 factor, and then the number of factors is increased until the reproduction of the observed eigenvalues fails to improve significantly. We evaluated the performance of PA, CD with known factorial structure, and 7 other techniques in a simulation study spanning a wide range of challenging data conditions. In terms of accuracy and robustness across data conditions, the CD technique outperformed all other methods, including a nontrivial superiority to PA. We provide program code to implement the CD technique, which requires no more specialized knowledge or skills than performing PA.
