Personality correlates of risky health outcomes: Findings from a large Internet study

Numerous studies have documented the effects of personality on health outcomes. However, which traits are most relevant to health, and the precise magnitude of their effects, is inconsistent across studies. The present study used a large sample (N = 460,172) to replicate and extend the relations between the Big Five and three health-related outcomes: self-reported health, body mass index, and substance use. Low Conscientiousness predicted all outcomes, indicating that individuals who are less responsible and less self-controlled tend to report poorer health, be more overweight, and engage in more substance use. Individuals who were more emotionally unstable (high Neuroticism) reported poorer health, and individuals prone to seek out social experiences and rewards (high Extraversion) engaged in more frequent substance use.

The location of the Trait Emotional Intelligence in the Zuckerman's Personality Model space and the role of General Intelligence and social status

The aim of this study was to investigate the relationships between Emotional Intelligence (EI) measured by the Trait Emotional Intelligence Questionnaire (TEIQue) and personality measured by the Zuckerman‐Kuhlman‐Aluja Personality Questionnaire (ZKA‐PQ) with the purpose of analyzing similarities and differences of both psychological constructs. Additionally, we studied the relationship among EI, personality, General Intelligence (GI) and a social position index (SPI). Results showed that the ZKA‐PQ predicts the 66% (facets) and the 64% (factors) of the TEIQue. High scores in EI correlated negatively with Neuroticism (r: –0.66) and Aggressiveness (r: –0.27); and positively with Extraversion (r: 0.62). Oblique factorial analyses demonstrated that TEIQue scales were located basically in the Neuroticism and Extraversion factors. The SPI and GI no loaded in any factor. These findings showed that EI is a not a distinct construct of personality and it cannot be isolated in the ZKA‐PQ personality space. GI is related with the SPI (r: 0.26), and EI correlated with GI (r: 0.18) and SPI (r: 0.16). Nevertheless, we found differences between GI high groups and the TEIQue and ZKA‐PQ factors when controlling age and sex. These findings are discussed in the individual differences context.     

Corporate Capitalism and the Common Good: A Framework for Addressing the Challenges of a Global Economy

This article ventures a framework for assessing the contributions capitalism might make to the common good. Capitalism has manifest strengths—efficiency, growth, support for human freedoms, encouragement for collaboration among nations that are not natural allies. Processes that generate these goods have negative consequences as well—the exploitation of labor, environmental harm, the marginalization of the "least advantaged," the reduction of politics to strategies for advancing special interests. To constrain the negative consequences, public oversight is necessary. The challenge is to devise policies that will limit the harms while protecting conditions that enable free markets to flourish. The paper concludes with an illustrative sketch of policy proposals that exemplify this goal.     

Testing attitudes,social desirability and behavioral regulations as moderators of implicit-explicit exercise discrepancies: A replication study in Iranian students

IntroductionThere is mixed evidence regarding moderators of the relationship between implicitly and explicitly measured constructs. This study examined this issue with evaluations of exercise relative to health or appearance in a sample of Iranian adolescents. Investigaing automatic associations and reflective constructs might provide important implications for developing interventions targeting exercise behavior in a population with different cultural, social, and economic barriers to exercise than European or North American adolescents.MethodsParticipants were 471 students enrolled in grades 9 to 12, of whom 269 (54.9%) were female. Behavioral regulations, explicit attitudes, and social desirability were investigated as possible moderators. All students completed questionnaire measures of physical activity behavior, attitudes, social desieality and behavioral regulation. They also completed two Go/No Go Association tasks to measure automatic associations of exercise with health and apperarance.ResultsAttitude was a significant moderator of discrepancies between automatic associations of exercise with health and health motives. Interjected regulation moderated implicit-explicit appearance discrepancies. Participants with low social desirability and negative automatic appearance associations had the highest appearance motivation.ConclusionsParticipants focused on the potential of achieving positive health outcomes of exercise rather than physical appearance outcomes, which differs from research from other countries. It is possible that, health was strongly linked with exercise by the pervasive societal pressures in Iran to have a healthy body.     

Reliable change in neuropsychological test scores is associated with brain atrophy in older adults

The reliable change index (RCI) is a commonly used method for interpreting change in neuropsychological test scores over time. However, the RCI is a psychometric method that, to date, has not been validated against neuroanatomical changes. Longitudinal neuroimaging and neuropsychological data from baseline and one-year follow-up visits were retrieved from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. The RCI was used to identify participants showing reliable decline on memory (ADNI-Mem; N = 450) and executive functioning (ADNI-EF; N = 456) factor scores. For each factor score, two groups (reliable change vs. no reliable change) were matched on potential baseline confounding variables. Longitudinal neuroanatomical data were analysed using tensor-based morphometry. Analysis revealed that reliable change on ADNI-Mem was associated with atrophy in the medial temporal cortex, limbic cortex, temporal lobe and some regions of the parietal lobe. Similar atrophy patterns were found for reliable change on ADNI-EF, except that atrophy extended to the frontal lobe and the atrophy was more extensive and of higher magnitude. The current study not only validates clinical usage of the RCI with neuroanatomical evidence of associated underlying brain change but also suggests patterns of likely brain atrophy when reliable cognitive decline is detected.     

Triangulating causality between childhood obesity and neurobehavior: Behavioral genetic and longitudinal evidence

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested. We filled this gap by using the Adolescent Brain Cognitive Development study cohort comprising 11,875 children aged 9–10. First, correlations between the age- and sex-specific 95th BMI percentile (%BMIp95) and neurobehavioral measures were cross-sectionally analyzed. Effects were then aggregated by neurobehavioral domain for causal analyses. Behavioral genetic Direction of Causation modeling was used to test the direction of each relationship. Findings were validated by longitudinal cross-lagged panel modeling. %BMIp95 correlated with impulsivity, motivation, psychopathology, eating behavior, and cognitive tests (executive functioning, language, memory, perception, working memory). Greater %BMIp95 was also associated with reduced cortical thickness in frontal and temporal brain areas but with increased thickness in parietal and occipital areas. Similar although weaker patterns emerged for cortical surface area and volume. Behavioral genetic modeling suggested causal effects of %BMIp95 on eating behavior (β = 0.26), cognition (β = 0.05), cortical thickness (β = 0.15), and cortical surface area (β = 0.07). Personality/psychopathology (β = 0.09) and eating behavior (β = 0.16) appeared to influence %BMIp95. Longitudinal evidence broadly supported these findings. Results regarding cortical volume were inconsistent. Results supported causal effects of obesity on brain functioning and morphology. The present study highlights the importance of physical health for brain development and may inform interventions aimed at preventing or reducing pediatric obesity.

Research Highlights

• A continuous measure related to obesity, %BMIp95, has correlations with various measures of brain functioning and structure
• Behavioral genetic and longitudinal modeling suggest causal links from personality, psychopathology, and eating behavior to %BMIp95
• Results also indicate directional links from %BMIp95 to eating behavior, cognition, cortical thickness, and cortical surface area
• Obesity may play a role for healthy brain development during childhood
