Development of an eight-subtest short form of the WISC-IV and evaluation of its clinical utility in children with traumatic brain injury

This study evaluated the degree to which an 8-subtest short form of the Wechsler Intelligence Scale for Children—Fourth Edition would yield acceptable estimates of the long-form Full-Scale IQ index while clarifying the underlying factor structure in a sample of 100 children and adolescents with traumatic brain injury. The short-form Full-Scale IQ had sufficient (i.e., at least two thirds) nonerror covariance with its full-length counterpart. In addition, a sufficient proportion (i.e., > 80%) of these short-form estimates fell within the 90% confidence interval of the respective full-length scores. Importantly, the elimination of 2 subtests, and in particular the Picture Concepts subtest, resulted in a factor structure where each remaining subtest was fairly specifically associated with its intended scale. It is concluded that this short form can be used clinically in children with traumatic brain injury without sacrificing reliability and with more straightforward interpretability at the level of the factor index scores.     

Slow and steady wins the race: Life history,mate value,and mate settling

Life history theory explains how individuals decide to invest their limited resources, which involves several trade-offs. Particularly relevant to the current work, individuals can choose to invest in current or delayed reproduction (a slow life history strategy), which implicates a trade-off between the quantity and the quality of one’s offspring. Choosing to delay reproduction allows for increased self-investment, and previous research has demonstrated that traits requiring self-investment are related to higher mate value. As such, the current study hypothesizes that slow life history strategy will predict high personal mate value and high levels of partner mate-value within heterosexual partnerships. Similarly, those with a slow life history strategy should display fewer tendencies toward mate-settling. The current work employs both subjective and objective measures of mate value within mateships to investigate these hypothesized relationships. As hypothesized, significant positive relationships among life history and mate value were detected, suggesting that a slower life history strategy corresponds to high ratings of mate value for both self and partner. Also, life history strategy is a significant predictor of subjective, objective, and Mate Value Inventory ratings of partner and self. Further implications and potential future works are discussed.     

The intervening role of Agreeableness in the relationship between Trait Emotional Intelligence and Machiavellianism: Reassessing the potential dark side of EI

Previous research into the potential ‘dark’ side of trait emotional intelligence (EI) has repeatedly demonstrated that trait EI is negatively associated with Machiavellianism. In this study, we reassess the potential dark side of trait EI, by testing whether Agreeableness mediates and/or moderates the relationship between trait EI and Machiavellianism. Hypothesized mediation and moderation effects were tested using a large sample of 884 workers who completed several self-report questionnaires. Results provide support for both hypotheses; Agreeableness was found to mediate and moderate the relationship between trait EI and Machiavellianism. Overall, results indicate that individuals high in trait EI tend to have low levels of Machiavellianism because they generally have a positive nature (i.e. are agreeable) and not because they are emotionally competent per se. Results also indicate that individuals high in ‘perceived emotional competence’ have the potential to be high in Machiavellianism, particularly when they are low in Agreeableness.     

Rushton’s contributions to the study of mental ability

This essay describes Rushton’s contribution to examining the nexus of intelligence, race, and genetics, specifically what I termed “Spearman’s hypothesis”. It states that Black–White differences are “most marked in just those [tests] which are known to be saturated with g”. I (Jensen) had confirmed this hypothesis using large data sets in the 1970s and 1980s and also found that Black–White differences were most marked on the more heritable rather than the more cultural subtests. Rushton confirmed and extended these findings in many highly innovative ways and demonstrated Spearman’s hypothesis applied among samples of Gypsy Roma in Serbia, and East Asian, European, South Asian, Colored and Black samples in South Africa. He has not only documented group differences in brain size, intelligence, life span, family structure, infant mortality, developmental precocity, personality, and temperament, and rates of two egg twinning, and crime among East Asians, Europeans, and Africans, but also provided a life history theory that explains them.     

Rushton’s r–K life history theory of race differences in penis length and circumference examined in 113 populations

 and r–K life history theory that Mongoloids are the most K evolved, Caucasoids somewhat less K evolved, and Negroids the least K evolved is examined and extended in an analysis of data for erect penis length and circumference in two new data sets. These new data extend Rushton’s theory by presenting disaggregated data for penis size for European and North African/South Asian Caucasoids; for East Asian and Southeast Asian Mongoloids; for Inuit and Amerindians and Mestizos, and for thirteen mixed race samples. The results generally confirm and extend Rushton’s r–K life history theory.     

Resolute ignorance on race and Rushton

I review Rushton’s research on the evolutionary divergence of the three major human lineages. His life-history theory predicts, and his multiple analyses document, a consistent three-way patterning of mean differences among blacks, whites, and East Asians on coevolved sets of morphological, physiological, developmental, psychological, and behavioral traits. I then analyze a typical example of how critics evaluate his work, including the rate at which they cast his scientific hypotheses, methods and conclusions in politically charged language. The set of articles in question, although authored by well-known academics and appearing in a major, peer-reviewed journal, illustrate how mob science works to “discredit” valid research and enforce collective ignorance about entire bodies of evidence. Rushton is a scholar and gentleman but it appears that his critics often act like neither.     

Les soignants face au burnout : quelles attributions causales ?

The objective of this study was to investigate the nature of the explanations produced by nurses when they are questioned about professional situations related with professional exhaustion such as burnout (BO), independently of a real-life situation of BO. The analysis of the 30 nurses’ adherences to causal explanations scale constructed and validated for this purpose showed greater adherence to internal causal explanations, both controllable and non-controllable, as explanations under external causalities, whatever the professional situation mentioned. The discussion focuses on the relevance of a psychosocial approach of explanations of the BO situations and its implications in terms of primary prevention of psychosocial risks in occupational context.     

Measuring psychotherapy outcomes in routine practice: Examining Slovak versions of three commonly used outcome instruments

This study examined the Slovak mutations of three outcome measures for routine practice i.e. the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM), the Outcome Questionnaire – 45 (OQ-45), the Outcome Rating Scale (ORS), and one control measure the Symptom Checklist 10 Revised (SCL-10R), with regard to their concordance or differences in outcome classification of pre-post change, when used by the same patients and when the criteria used for establishing recovery and improvement status are based on the same sample. Method: Non-clinical (252) and clinical (202) samples were used for the standardisation of all instruments. A portion of the clinical participants (N?=?140) completed all measures at the end of their treatment. Results: The CORE-OM, and the SCL-10R indicated a higher number of recovered and improved clients. With regard to the pre-post differences as expressed in the effect size, the CORE-OM showed the highest pre-post difference (pre-post effect size .98), followed by the ORS (.87), the SCL-10R (.83) and finally with the OQ-45 (.69). Conclusion: Even very similar instruments developed on the basis of similar theoretical conceptualisations and empirical findings may report different pre-post outcomes.     

Types of self-reported anxiety in outpatients with DSM-III-R anxiety disorders1

To ascertain whether psychiatric outpatients can be classified into distinct types according to their self-reported symptoms of anxiety, the Beck Anxiety Inventory (BAI) was administered to 655 outpatients diagnosed with DSM-III-R anxiety disorders. Cluster analysis identified three internally consistent subscales representing subjective, somatic, and panic symptoms. Further analysis revealed six types of outpatients reflecting below average, panic-subjective, low subjective, low somatic-panic, above average, and subjective-somatic anxiety. The types were differentiated with respect to age, primary diagnosis, clinically rated anxiety, and both self-reported and clinically rated depression.
