Childhood intelligence predicts premature mortality: Results from a 40-year population-based longitudinal study

Childhood intelligence has been shown to predict mortality risk in adulthood. This relation has never been investigated in a Central European country with universal health care. The present study investigated whether childhood intelligence predicts mortality risk across 40 years in Luxembourg. 2543 participants completed an intelligence test at age 12 in 1968, and the mortality rate in this sample until 2008 was recorded. Our results showed that higher childhood intelligence predicted a lower risk for mortality, even when childhood socioeconomic status was controlled for. This effect was strongest in men belonging to the group of the lowest 20% in intelligence. These results indicate that even universal access to health care cannot fully offset the cumulative effects of intelligence on mortality.     

The role of psychosocial processes in explaining the gradient between socioeconomic status and health

The gradient between socioeconomic status (SES) and health is well established: Many measures of health show that health increases as SES increases. However, the mechanisms underlying this association are not well understood. Behavioral, cognitive, and affective tendencies that develop in response to the greater psychosocial stress encountered in low-SES environments may partially mediate the impact of SES on health. Although these tendencies might be helpful for coping in the short term, over time they may contribute to the development of allostatic load, which increases vulnerability to disease. Debate remains regarding the direction of causation between SES and health, the impact of income inequality, the interaction of SES with race-ethnicity and gender, and the effects of SES over the life course.     

Childhood and adolescent predictors of early adult career pathways

Individual and contextual factors in childhood and adolescence that were hypothesized to contribute to career pathways were examined in a prospective study. Four career pathway groups were distinguished in a sample of 202 at-risk men (23-24 years of age); namely, young men with long-term unemployment, short-term unemployment, full employment, or a college education. Measures of educational attainment, family and peer characteristics, and personal adjustment during childhood and adolescence were used to determine if they would predict early adult career pathways. Findings indicated that the long-term unemployed young men, overall, showed the poorest levels of educational attainment, family and peer characteristics, and personal adjustment during childhood and adolescence.The most important predictors of differing career pathways were educational attainment, arrests, and mental health problems. Implications of the findings for conceptualizing the school-to-work transition within an integrative framework are discussed.     

Independent effects of bilingualism and socioeconomic status on language ability and executive functioning

One hundred and seventy-five children who were 6-years old were assigned to one of four groups that differed in socioeconomic status (SES; working class or middle class) and language background (monolingual or bilingual). The children completed tests of nonverbal intelligence, language tests assessing receptive vocabulary and attention based on picture naming, and two tests of executive functioning. All children performed equivalently on the basic intelligence tests, but performance on the language and executive functioning tasks was influenced by both SES and bilingualism. Middle-class children outperformed working-class children on all measures, and bilingual children obtained lower scores than monolingual children on language tests but higher scores than monolingual children on the executive functioning tasks. There were no interactions with either group factors or task factors. Thus, each of SES and bilingualism contribute significantly and independently to children’s development irrespective of the child’s level on the other factor.     

The association between low socioeconomic status and depressive symptoms depends on temperament and personality traits

Socioeconomic status and personality traits are known to be associated with depression risk. We examined whether temperament and personality traits modified the association between socioeconomic status and depressive symptoms. The participants were 2678 individuals from the Cardiovascular Risk in Young Finns study, aged 18-49 during the three study waves in 1997, 2001, and 2007 included in the present study. Temperament was assessed with the Temperament and Character Inventory, personality with the Five Factor Model, and depressive symptoms with a modified version of Beck’s Depression Inventory. Education, occupational status, and income level were used as indicators of socioeconomic status. Results of multilevel linear regression analysis indicated that low occupational status and income were associated with high depressive symptoms particularly in individuals with high neuroticism or harm avoidance, and with low extraversion or reward dependence. High persistence also strengthened the negative association between income and depressive symptoms, but this interaction effect was not observed with conscientiousness. The mental health risks of low socioeconomic status may therefore be most potent among individuals who are sensitive to negative and threatening stimuli.     

Gender-linked personality and mental health: The role of trait emotional intelligence

The present study examined the role of the emotion-related personality dimension, or trait emotional intelligence (EI), in the relationship between gender-linked personality (GLP) traits and internalizing mental health difficulties (IMHDs). GLP traits were measured as Agency and Communion, due to conceptual advantages over other semantic representations (e.g., masculinity, femininity) in the literature. IMHDs as the outcome variable were conceptualized as a latent composite of anxiety, stress, and emotion-oriented coping. A moderate relationship between Agency and IMHDs was fully mediated by trait EI. Trait EI also divided an overall non-significant effect of Communion on IMHDs into an indirect, protective effect via trait EI and a direct, adverse effect. The results suggest that Agency and Communion subsume different sets of trait EI facets, which may account for much of the differential protective effects of these GLP traits on IMHDs. Discussion focuses on implications of the results for sex differences in mental health.

The mediating role of work locus of control on the relationship among emotional intelligence,organisational citizenship behaviours,and mental health among nurses

Using a cross‐sectional design to evaluate the perceptions of 242 nurses working in a Malaysian hospital, this study investigates the mediating role of work locus of control (WLOC) on the relationship among emotional intelligence (EI), organisational citizenship behaviours (OCBs), and mental health among nurses. Additionally, the role of EI is examined. Findings indicate that EI correlates positively with OCBs and negatively with mental health and that WLOC mediates the relationship between EI and OCBs. However, WLOC does not mediate the relationship between EI and mental health. An in‐depth understanding of nurses' EI provides insights into health institution management to increase organisational outcomes. Results of this study are interpreted to indicate that EI should be part of nurse training and that OCBs are associated with performance and productivity. It is suggested that EI could also be included in selection processes to encourage growth and development of a health institution.     

Preventive behaviour and health status among the elderly

Abstract

The research describes the range of preventive health behaviours undertaken by the elderly, investigates the dimensionality of preventive health behaviour, and explores the relationship between preventive health behaviour, self-assessed and medically assessed health status. Previous research has relied mainly on self-reports of health status. Data from medical examinations and interviews with 115 elderly individuals (aged 65–75) indicated that most elderly persons performed some intentional preventive health practices, as well as a broad range of normative preventive health practices. Particular clusters of preventive health behaviour emerged when the data were subjected to cluster analysis. A short index consisting of five personal preventive health behaviours found in other studies to have a protective effect on long-term health was found to have a low to moderate correlation with the medical and self-assessments of health status employed in the study. These findings indicate particular types of preventive health behaviour of importance for health promotion programmes with the elderly.     

The role of psychological control,socioeconomic status and academic achievement in parents' educational aspirations for their adolescent children

The present study examined the associations between mothers' and fathers' psychological control, socioeconomic status (SES) and their role in parents' educational aspirations for their adolescent children. Moreover, we examined to what extent SES and psychological control predicted their child's grade point average (GPA) and educational aspirations. A total of 1,034 Finnish adolescents aged 15 to 16 and their parents (720 mothers, 542 fathers) were surveyed at the beginning of the last grade of compulsory school. The results showed that the use of psychological control was more common among parents with lower SES. Moreover, the lower parents' SES was and the more psychological control they imposed, the lower were their educational aspirations for their adolescent children and lower was their child's GPA. The impact of SES was partially mediated by psychological control. The effects were similar for mothers and fathers.     

Recent data for majority and racial minority differences in intelligence of 5 year olds in the United Kingdom

Data are presented from the UK Millennium Cohort Study for a sample of 14,860 5 year old British children giving the IQs of whites and racial minorities. Africans, Indians, Pakistanis and Bangladeshis obtained lower IQs than whites, while the IQ of the Chinese was higher. These group differences in IQ were consistent with the differences in educational attainments and earnings.     

Counselor perceptions of students who vary in gender and socioeconomic status

The present study experimentally examined how counselor perceptions of hypothetical students are affected by student gender and socioeconomic status (SES). Results showed that counselors perceive students from low SES backgrounds as having less promising futures and lower math abilities. Counselors also rated female students as lower in math abilities than male students. Our results indicate that institutions should consider providing more school counselor training to reduce bias based on gender and SES.

The status of the concept of intelligence

Psychometric studies have shown that “general intelligence” should be broken down into the ability to apply learned solutions to new problems (crystallized intelligence) and the ability to deal with novel intellectual problems (fluid intelligence). This distinction has been amplified upon by studies of individual differences in information processing. Crystallized intelligence depends on the problem-solving schema that people have acquired and upon their efficiency in accessing information in long-term memory. Fluid intelligence is associated with the ability to access and manage relatively large amounts of information in working memory. Measures of fluid and crystallized intelligence are important predictors of objectively measured workplace performance. Studies of actual and simulated workplaces have shown that this is largely due to differences in people's ability to manage information and the speed with which the details of a job can be grasped.     

Emotional intelligence predicts adolescent mental health beyond personality and cognitive ability

Emotional intelligence (EI) has been reliably linked to better mental health (Martins, Ramalho, & Morin, 2010). However, critics have argued that EI may be conceptually redundant and unable to offer anything new to the prediction of key adaptational outcomes beyond known correlates of performance, i.e., personality and cognitive ability (Brody, 2004). Although sparse, extant evidence points to differential incremental contributions from ability and trait EI in the prediction of internalising vs. externalising symptomatology in adults (e.g., [Gardner and Qualter, 2010] and [Rossen and Kranzler, 2009]). However, there is a dearth of research addressing these associations in adolescents. The current study explored the incremental validity of ability and trait EI to predict depression and disruptive behaviour beyond the ‘Big Five’ personality dimensions and general cognitive ability in a sample of 499 adolescents (mean age 13.02 years). Regression analyses found that collectively, EI made a significant, incremental contribution to the prediction of disorder in youth. However, of the two, trait EI appears the stronger predictor. Findings are discussed with reference to EI theory and directions for future research.     

Fluid intelligence is independently associated with all-cause mortality over 17 years in an elderly community sample: An investigation of potential mechanisms

The long-term relationship between lower intelligence and mortality risk in later life is well established, even when controlling for a range of health and sociodemographic measures. However, there is some evidence for differential effects in various domains of cognitive performance. Specifically, tests of fluid intelligence may have a stronger association with mortality than do tests of crystallized intelligence. The present study examines the relationship between intelligence and mortality in a sample of 896 Australian community-dwelling males and females, aged 70–97 at recruitment and followed for up to 17 years. There were 687 deaths during the follow-up period. Cox proportional hazard regression models examined whether the relationship between intelligence and mortality might be mediated by socioeconomic status, by health behaviors, by health status, or a combination of these. Higher fluid intelligence — as measured by the Symbol–Letter Modalities Test — was strongly associated with lower mortality rates (Hazard ratio = 0.80; 95% confidence interval = 0.72–0.88), even after accounting for any combination of potential mediators and confounders. A significant association between crystallized intelligence, as measured by the National Adult Reading Test, and mortality (HR = 0.89; 95% CI = 0.80–0.99) was attenuated by the inclusion of socioeconomic, health status measures, and health behavior measures and when deaths from the first four years of the study were excluded. The findings show little support for the hypothesized mechanisms of the intelligence–mortality relationship.
