Preschool hyperactivity specifically elevates long-term mental health risks more strongly in males than females: a prospective longitudinal study through to young adulthood.

Evidence of continuities between preschool hyperactivity and adult mental health problems highlights the potential value of targeting early identification and intervention strategies. However, specific risk factors are currently unclear. This large-scale prospective longitudinal study aimed to identify which hyperactive preschoolers are at the greatest long-term risk of poor mental health. One hundred and seventy children (89 females) rated as hyperactive by their parents, and 88 non-hyperactive controls (48 females) were identified from a community sample of 4215 3-year-olds. Baseline data relating to behavioral/emotional problems and background characteristics were collected. Follow-up mental health and functional impairment outcomes were collected between 14 and 25 years of age. At age 3 years, males and females in the hyperactive group had similarly raised levels of hyperactivity and other behavior problems. In adolescence/young adulthood, these individuals showed elevated symptoms of ADHD, conduct disorder, mood disorder, anxiety and autism, as well as functional impairment. Preschool hyperactivity was strongly predictive of poor adolescent/adult outcomes for males across domains with effects being specifically driven by hyperactivity. For females, the effects of preschool hyperactivity were smaller and dropped to non-significant levels when other preschool problems were taken into account. Environmental risk factors also differed between the sexes, although these may also have been mediated by genetic risk. In conclusion, these results demonstrate marked sex differences in preschool predictors of later adolescent/adult mental health problems. Future research should include a measure of preschool inattention as well as hyperactivity. The findings highlight the potential value of tailored approaches to early identification strategies.

Intelligence, Personality and Tolerance of Ambiguity.

In this study, 3836 adults completed a personality test (the HPTI) and a multidimensional intelligence test (GIA). Two prominent theories that link personality traits to intelligence (compensation and investment) were tested. There were more sex differences in the personality traits than in the IQ scores. Correlational and regression analyses results provided little evidence for either theory but pointed to the role of tolerance of ambiguity as a consistently significant, positive correlate of IQ at both the facet and domain levels. The role of this neglected trait is discussed. Limitations of various aspects of this study and its implications are considered.

Bright and Dark-Side Traits Associated With Interests in Commerce vs Science: Different Personality Profiles of the Scientist-Practitioner.

This study focused on the idea that there are predictable differences between those individuals who opt for Scientific rather than the Commerce/Practitioner jobs and consulting assignments. A total of 2278 adults from a variety of occupations completed three validated questionnaires: the first assessed the behavioural tendency of an individual when one is exposed to stress and which could derail one's business career (HDS: Hogan Development Survey); the second the values and preferences that indicate work motivation (MVPI: The Motives, Values and Preferences Inventory), and the third, seven bright-side personality factors (HPI: Hogan Personality Inventory). The MVPI measured interests in scientific and commercial/enterprising activities. Correlations, regressions and SEM indicated both similarities and differences in the relationship between personality traits and values. Bright-side personality traits accounted for more the variance for those interested in Science while dark-side traits accounted for more variance for those interested in the Commerce. The biggest difference occurred in Inquisitiveness (Curiosity, Openness to Experience) which was much higher for those interested in science. Implications for personnel selection, job-fit and promotion were discussed.

Hunt-Vitell's General Theory of Marketing Ethics Predicts "Attitude-Behaviour" Gap in Pro-environmental Domain.

The inconsistency between pro-environmental attitudes and behaviours, known as the "attitude-behaviour" gap, is exceptionally pronounced in scenarios associated with "green" choice. The current literature offers numerous explanations for the reasons behind the "attitude-behaviour" gap, however, the generalisability of these explanations is complex. In addition, the answer to the question of whether the gap occurs between attitudes and intentions, or intentions and behaviours is also unknown. In this study, we propose the moral dimension as a generalisable driver of the "attitude-behaviour" gap and investigate its effectiveness in predicting attitudes, pro-environmental intentions and subsequent behaviours. We do so by using Hunt-Vitell's moral philosophy-based framework of ethical decision-making, which conceptualises morality as the central decision-making parameter. The results from 557 US MTurk participants revealed that the manipulation of moral dimensions, specifically deontology and teleology, impacted ethical evaluation of presented dilemmas, however, failed to translate into subsequent intentions and behaviours. This finding suggests (i) that the moral dimension has an effect in shaping attitudes toward environmental issues, and (ii) that gap occurs between attitudes and intentions rather than intentions and behaviours. Further investigation of what strengthens and/or overrides the effects of the moral dimension would help understand the reasons why moral attitudes do not always translate into subsequent intentions and behaviours in the pro-environmental domain.

The Dark Side of High-Fliers: The Dark Triad, High-Flier Traits, Engagement, and Subjective Success.

The aim of this study was to understand the relationship between bright-side, High Potential and dark-side Dark Triad traits, as well as work engagement on judgements of perceived success. In all, 290 working adults completed questionnaires assessing their High Potential Personality Traits (HPTI), their dark-triad traits, job engagement and self-rated success at work. The data showed that the three dark-triad traits (Narcissism, Psychopathy, Machiavellianism) were systematically and significantly correlated with High Potential traits Adjustment/neuroticism, Tolerance of Ambiguity and Conscientiousness. Three HPTI traits, namely curiosity, Conscientiousness, and courage, were systematically positively correlated with all three engagement measures. Narcissism was strongly related to all measures of engagement. Those with higher scores Adjustment, Courage, and Narcissism and of the male sex, rated their success highest. Job engagement mediated between high-flier and dark-side traits and success ratings. Implications and limitations are discussed.

Intention to quit and the role of dark personality and perceived organizational support: A moderation and mediation model.

This study investigated the role of individual differences (dark personality) and situational factors (perceived organisational support) in explaining intention to quit. Four hundred and fifty-one (50 of which females) ambulance personnel completed three questionnaires (Hogan Development Survey; Perceived Organisational Support Survey; and a single item Intention to Quit measure) as a part of a selection and development assessment. Employees high on Excitable, Sceptical, and Mischievous, but low on Colourful were found to have greater intentions to quit. Additionally, employees high on Excitable, Sceptical, Reserved, and Leisurely, but low on Dutiful and Diligent had lower perceptions of organisational support. Structural Equation Modelling revealed that perceived organisational support plays both a mediating and moderating role on dark personality and intention to quit. Theoretical implications of personality's role in perceived organisational support and intention to quit are discussed.

Associations between childhood biomedical factors, maternal smoking, personality traits, Body and Mass Index and the prevalence of asthma in adulthood.

OBJECTIVE: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK. DESIGN: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used. MAIN OUTCOME MEASURE: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years. RESULTS: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38-10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18-2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00-1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02-1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01-1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76-0.96, p < .01), as well as sex (OR = 1.49: 1.15-1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood. CONCLUSION: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.

The associations between personality traits, education, occupation and the occurrence of eczema in adulthood.

There were 5834 participants with complete data on parental social class at birth, childhood cognitive ability tests scores at 11 years, educational qualifications at 33 years, the Big Five-Factor personality traits, occupational levels and eczema (measured at age 50 years). Results showed that eczema in childhood, educational achievement and occupational levels were significantly associated with the occurrence of reported eczema in adulthood. Emotionally Stable people (non-neurotic) were less likely to have eczema, but those with high Agreeableness and Openness more likely to have eczema. Childhood cognitive ability was significantly and positively associated with eczema in adulthood.

The Dark Side of Resilience and Burnout: A Moderation-Mediation Model.

This study tested whether specific dark-side traits may be beneficial in manifesting and maintaining Resilience, whilst others are vulnerability factors for Burnout. Four hundred and fifty-one (50 female) ambulance personnel completed three questionnaires as a part of a selection and development assessment. The study utilised the Hogan Development survey as a measure of dark side personality, the Copenhagen Burnout Inventory to assess work-related burnout, and the Resilience Scale- 14 to measure resilience levels. Those high on Excitable and Cautious but low on Bold and Reserved were linked to an increased vulnerability to Burnout. Also those high on Bold and Diligent yet low on the Excitable, Cautious, and Imaginative scales were more resilient. Structural Equation Modelling revealed that resilience plays both a mediating and moderating role on personality and burnout. Theoretical implications suggest future research assessing the predictive capacity of psychological variables on burnout should account the indirect effect of resilience.

Hay fever in childhood, traits Neuroticism and Conscientiousness as independent predictors of the occurrence of hay fever in adulthood.

The study investigated the associations between social and psychological factors in childhood and adulthood and the occurrence of adulthood hay fever in a longitudinal birth cohort study. A total of 5780 participants with data on parental social class, childhood hay fever up to age 7 years, childhood cognitive ability at age 11 years, educational qualifications at age 33 years, personality traits, occupational levels and adult hay fever (all measured at age 50 years) were included in the study. Using logistic regression analyses, results showed that childhood hay fever identified by medical doctors and traits Emotional Stability and Conscientiousness were significantly and independently associated with the occurrence of hay fever in adulthood.

Childhood onset of migraine, gender, parental social class, and trait neuroticism as predictors of the prevalence of migraine in adulthood.

This study investigated the effects of socio-demographic and psychological factors in childhood and adulthood on the prevalence of migraine in adulthood using data from The National Child Development Studies (NCDS), a birth cohort in the UK. The analytical sample comprises 5799 participants with complete data. Logistic regression analysis showed that higher professional parental social class (OR=2.0: 1.05, 3.86, p<0.05), female sex (OR=2.24: 1.68-2.99, p<0.001), migraine in childhood diagnosed by physicians (OR=1.76: 1.23-2.50, p<0.01), and higher trait neuroticism (OR=1.17:1.26-1.06, p<0.01):<0 were all significantly associated with the prevalence of migraine in adulthood. Both socio-demographic and personality factors were significantly associated with the prevalence of migraine in adulthood.

Associations between Familial Factor, Trait Conscientiousness, Gender and the Occurrence of Type 2 Diabetes in Adulthood: Evidence from a British Cohort.

OBJECTIVE: To investigate social, familial, and psychological factors in influencing the occurrence of type 2 diabetes in adulthood. METHOD: Some 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33, and 50 years of age. The prevalence of type 2 diabetes at age 50 years was the outcome measure. RESULTS: Some 5,032 participants with data on parental social class, childhood cognitive ability tests scores at age 11 years, educational qualifications at age 33 years, personality traits, occupational levels, and type 2 diabetes (all measured at age 50 years) were included in the study. Available information also included whether cohort members' parents or siblings had diabetes. Using logistic regression analyses, results showed that sex (OR=0.63: 0.42-0.92, p<.05), family history (OR=3.40: 1.76-6.55, p<.01), and trait conscientiousness (OR=0.76: 0.64-0.90, p<.001) were all significantly and independently associated with the occurrence of type 2 diabetes in adulthood. It appears that the occurrence of type 2 diabetes is greater among men than women (4.3% vs 2.5%). CONCLUSION: Familial (genetic and non-genetic) and psychological factors are significantly associated with the prevalence of type 2 diabetes in adulthood.
