Personality correlates of life values

The present study sought to determine whether significant relationships exist between life value preferences and personality traits and to describe the nature of any relationships identified. Administered to 310 undergraduate and graduate students were the 16 PF personality inventory and a 55-item Life Values Inventory which assessed values governing life styles and orientations. A factor analysis of the Life Values Inventory resulted in the identification of 14 life values dimensions. Factor scores for these 14 dimensions were then employed in a canonical analysis and a factor analysis with the 16 PF scores. The canonical analysis yielded results significant at the .001 level. The factor analysis yielded 10 factors, many of which displayed shared common-factor variance between Life Values and 16 PF variables. The interpretation of that shared variance identified several personality correlates of life values that suggested causal and developmental interactions of some value in describing and explaining human behavior.     

Personality and obesity across the adult life span

Personality traits contribute to health outcomes, in part through their association with major controllable risk factors, such as obesity. Body weight, in turn, reflects our behaviors and lifestyle and contributes to the way we perceive ourselves and others. In this study, the authors use data from a large (N = 1,988) longitudinal study that spanned more than 50 years to examine how personality traits are associated with multiple measures of adiposity and with fluctuations in body mass index (BMI). Using 14,531 anthropometric assessments, the authors modeled the trajectory of BMI across adulthood and tested whether personality predicted its rate of change. Measured concurrently, participants higher on Neuroticism or Extraversion or lower on Conscientiousness had higher BMI; these associations replicated across body fat, waist, and hip circumference. The strongest association was found for the impulsivity facet: Participants who scored in the top 10% of impulsivity weighed, on average, 11Kg more than those in the bottom 10%. Longitudinally, high Neuroticism and low Conscientiousness, and the facets of these traits related to difficulty with impulse control, were associated with weight fluctuations, measured as the variability in weight over time. Finally, low Agreeableness and impulsivity-related traits predicted a greater increase in BMI across the adult life span. BMI was mostly unrelated to change in personality traits. Personality traits are defined by cognitive, emotional, and behavioral patterns that likely contribute to unhealthy weight and difficulties with weight management. Such associations may elucidate the role of personality traits in disease progression and may help to design more effective interventions.     

Personality predictors of the time course for lung cancer onset

Numerous findings suggest that personality is linked to the incidence and experience of negative health outcomes. More specifically, trait negative affect is negatively related to a number of health outcomes. The current study expands our understanding of the link between personality and disease by examining the time course for lung cancer onset. In a sample of patients who had recently undergone surgical resection for lung cancer, a variety of negative affect related personality variables were assessed to determine their relationship with age at surgery. After controlling for smoking behavior, it was found that trait negative affect was associated with time course for lung cancer onset, such that those with higher (vs. lower) levels of trait negative affect manifested lung cancer earlier in their lives. Thus, trait negative affect represents an independent risk factor among those prone to lung cancer (i.e., smokers).     

Personality functioning in patients with a progressive course of multiple sclerosis

This study intended to describe general personality functioning in patients with a progressive course of multiple sclerosis. 55 consecutive rehabilitation inpatients with progressive course of multiple sclerosis were assessed with a multimethod test battery: the Expanded Disability Status Scale, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Rosenberg Self-esteem Scale, and the Rorschach Test administered and scored with Comprehensive System. The control group comprised 55 healthy participants with similar sociodemographic characteristics. Specific differences were found for both cognitive and affective aspects, as the patients with progressive course of multiple sclerosis had less positive self-image, less effective mediation processing, and an affective approach to reality. Present data illustrated the usefulness of examining patients with a progressive course of multiple sclerosis to identify abilities and difficulties in cognitive and affective patterns, and support better adaptation to relationships and the environment.     

Personality and life satisfaction: a facet-level analysis

At the global level of the Big Five, Extraversion and Neuroticism are the strongest predictors of life satisfaction. However, Extraversion and Neuroticism are multifaceted constructs that combine more specific traits. This article examined the contribution of facets of Extraversion and Neuroticism to life satisfaction in four studies. The depression facet of Neuroticism and the positive emotions/cheerfulness facet of Extraversion were the strongest and most consistent predictors of life satisfaction. These two facets often accounted for more variance in life satisfaction than Neuroticism and Extraversion. The findings suggest that measures of depression and positive emotions/cheerfulness are necessary and sufficient to predict life satisfaction from personality traits. The results also lead to a more refined understanding of the specific personality traits that influence life satisfaction: Depression is more important than anxiety or anger and a cheerful temperament is more important than being active or sociable.     

Personality, social support, and psychological distress in later life

A conceptual model was developed to address 2 issues that have received relatively little attention in the social support literature. First, an attempt was made to assess the interrelationships among 3 types or dimensions of supportive social relations. In addition, the impact of selected psychological and social factors on social support use was examined. Findings from a nationwide survey of older adults in the United Kingdom suggest that social contact tends to increase the amount of received support, and received support in turn tends to bolster perceptions of support availability in the future (i.e., anticipated support). With regard to the second issue, social roles (especially marital status) and social extraversion emerged as potentially important correlates of social support use in later life.     

Personality traits and life satisfaction among online game players.

The DFC Intelligence predicts worldwide online game revenues will reach $9.8 billion by 2009, making online gaming a mainstream recreational activity. Understanding online game player personality traits is therefore important. This study researches the relationship between personality traits and life satisfaction in online game players. Taipei, Taiwan, is the study location, with questionnaire surveys conducted in cyber cafe shops. Multiple regression analysis studies the causal relationship between personality traits and life satisfaction in online game players. The result shows that neuroticism has significant negative influence on life satisfaction. Both openness and conscientiousness have significant positive influence on life satisfaction. Finally, implications for leisure practice and further research are discussed.     

The developmental course of lexical tone perception in the first year of life

Perceptual reorganisation of infants' speech perception has been found from 6 months for consonants and earlier for vowels. Recently, similar reorganisation has been found for lexical tone between 6 and 9 months of age. Given that there is a close relationship between vowels and tones, this study investigates whether the perceptual reorganisation for tone begins earlier than 6 months. Non-tone language English and French infants were tested with the Thai low vs. rising lexical tone contrast, using the stimulus alternating preference procedure. Four- and 6-month-old infants discriminated the lexical tones, and there was no decline in discrimination performance across these ages. However, 9-month-olds failed to discriminate the lexical tones. This particular pattern of decline in nonnative tone discrimination over age indicates that perceptual reorganisation for tone does not parallel the developmentally prior decline observed in vowel perception. The findings converge with previous developmental cross-language findings on tone perception in English-language infants [Mattock, K., & Burnham, D. (2006). Chinese and English infants' tone perception: Evidence for perceptual reorganization. Infancy, 10(3)], and extend them by showing similar perceptual reorganisation for non-tone language infants learning rhythmically different non-tone languages (English and French).     

Siblings of individuals with autism spectrum disorders across the life course

In this article, we review the literature on siblings of individuals with autism spectrum disorders (ASD) from a lifespan developmental perspective, from infancy through adulthood, focusing on the sibling relationship and sibling well-being. We situate this review within the larger body of research on siblings of individuals with developmental disabilities (DD) across the lifespan. We then consider the genetic aspects of ASDs and their implications for siblings. We conclude that there is an evidence of atypical social and communication development in some siblings of children with an ASD during infancy. During childhood and adolescence, siblings describe both positive and negative aspects of their sibling relationship and there is some evidence that siblings of children with an ASD may be at heightened risk for social and behavioral adjustment problems. The limited research on adulthood suggests that lack of closeness in the sibling relationship and social and emotional difficulties may continue. We encourage more attention focused on developmental issues, specifically with respect to samples in narrower age groups and in longitudinal research. Finally, we note the variability in sibling outcomes, and suggest further examination of potential moderating and mediating factors, including genetic predispositions.     

Personality characteristics of highly generative adults as assessed in Q-sort ratings of life stories

The present study compared the personality characteristics assessed in life stories of 40 highly generative adults to those in the life stories of a contrasting sample of 30 less generative adults. Life-story interviews of all 70 subjects were rated with the California Adult Q-Sort (CAQ; Block, 1961). The results were compared to the “expert” generativity CAQ profile compiled by Peterson and Klohnen (1995). The results indicated that highly generative adults were more likely to construct life stories indicative of such positive generativity characteristics as “behaves in a giving way toward others” and “is turned to for advice and reassurance” compared to adults low in generativity. Furthermore, the highly generative adults related life-story accounts in which negative generativity qualities such as “has hostility toward others” and “is self-indulgent” were more uncharacteristic than those expressed in the low-generativity adults' stories. The study adds to a growing empirical literature on the meaning and manifestations of generativity in adult lives and suggests that the CAQ is a useful tool for uncovering personality characteristics expressed in the life-story accounts generated by adults.     

Personality neglect. The unforeseen impact of personal dispositions on emotional life

The present research provides the first evidence that people neglect their own personalities when they envision their future emotional lives. In Study 1, students ignored the impact of their dispositional happiness in predicting how they would feel 2 weeks after receiving grades. Yet dispositional happiness played an important role in shaping actual emotional experiences. Similarly, exhibiting personality neglect, participants in Study 2 overlooked their trait levels of neuroticism and optimism when forecasting their reaction to Barack Obama's election, though these personality dimensions were related to their actual emotional reactions. Because they overlooked the influence of their own dispositions, individuals incorrectly predicted their future feelings. Ironically, as a result of this personality neglect, more optimistic individuals were less likely to see their emotional future in an overly rosy light, whereas more neurotic individuals were more likely to overestimate the pleasure that the future would bring.     

Personality development across the life span: longitudinal analyses with a national sample from Germany

Longitudinal data from a national sample of Germans (N = 20,434) were used to evaluate stability and change in the Big Five personality traits. Participants completed a brief measure of personality twice, 4 years apart. Structural equation modeling techniques were used to establish measurement invariance over time and across age groups. Substantive questions about differential (or rank-order) and mean-level stability and change were then evaluated. Results showed that differential stability was relatively strong among all age groups but that it increased among young adults, peaked in later life, and then declined among the oldest old. Patterns of mean-level change showed that Extraversion and Openness declined over the life span, whereas Agreeableness increased. Mean levels of Conscientiousness increased among young adults and then decreased among older adults. Trajectories for Neuroticism were relatively flat, with slight increases during middle age and a slight decline in late life.     

Personality in its natural habitat: manifestations and implicit folk theories of personality in daily life

To examine the expression of personality in its natural habitat, the authors tracked 96 participants over 2 days using the Electronically Activated Recorder (EAR), which samples snippets of ambient sounds in participants' immediate environments. Participants' Big Five scores were correlated with EAR-derived information on their daily social interactions, locations, activities, moods, and language use; these quotidian manifestations were generally consistent with the trait definitions and (except for Openness) often gender specific. To identify implicit folk theories about daily manifestations of personality, the authors correlated the EAR-derived information with impressions of participants based on their EAR sounds; judges' implicit folk theories were generally accurate (especially for Extraversion) and also partially gender specific. The findings point to the importance of naturalistic observation studies on how personality is expressed and perceived in the natural stream of everyday behavior.     

A motivation-enhancing treatment to sustain goal engagement during life course transitions

Although theory-driven control striving treatments may sustain motivation for individuals navigating life course transitions, their efficacy during these challenging junctures remains unexamined. In a pre-post randomized field study (n = 316), a novel control striving treatment based on Heckhausen et al.’s (Psychol Rev 117:32–60, 2010) motivational theory of life-span development was administered to young adults making the landmark transition to university. For students who faced obstacles to goal attainment, the motivation-enhancing selective secondary control (SSC) striving treatment (vs. no-treatment) increased performance by 8 % in a two-semester course (74.85 % vs. 66.68 %). Consistent with theory, the SSC treatment-performance linkage was mediated by selective secondary and selective primary control in a hypothesized causal sequence. Findings advance the literature by showing control striving treatments can improve performance for some young adults in transition by promoting adaptive changes in theoretically-derived psychological process variables.     

Parental bond and life course transitions from adolescence to young adulthood

In this study the effects of life course transitions in adolescence and young adulthood (leaving the parental home, living together with a partner,entering parenthood, and becoming financially independent) on the parent-child bond are investigated. Data are presented from a three-wave study of 1,064 adolescents and young adults (aged 12-24 years at Wave 1) over a six-year period. As the youth in this study proceeded through the life course, they tended to report a closer parental bond. However, this age-related effect was counterbalanced by a tendency toward a weakened bond with parents following departure from the parental home. Results are in line with individuation theory, which contends that parent-child relationships become less close as a result of transitions leading to more autonomy.     

Personality trait change and life satisfaction in adults: The roles of age and hedonic balance

This paper examines whether changes in personality traits influenced life satisfaction (LS). This involved investigating whether these associations were moderated by age and mediated by hedonic balance (i.e., positive and negative affect). Participants included 11,104 Australian adults aged 18–79 years, with data available from two time points (baseline and 4-year follow up). Latent difference score modeling indicated that increased neuroticism was associated with lower LS, whereas increased extraversion, conscientiousness, and agreeableness were associated with higher LS. These relationships were moderated by age, and were less evident in older adults. Hedonic balance partially mediated the relationships between change in neuroticism and extraversion with LS. These findings provide important insights into longitudinal associations between personality change and LS.     

Personality and mortality risk across the life span: the importance of conscientiousness as a biopsychosocial attribute.

OBJECTIVE: This study addressed whether personality in childhood and personality in adulthood are independent predictors of mortality risk and the extent to which behavioral and other psychosocial factors can explain observed relationships between personality and mortality risk. DESIGN: This was a prospective longitudinal cohort study of 1,253 male and female Californians over 7 decades (1930-2000). Proportional hazards regressions were the principal analyses. MAIN OUTCOME MEASURES: Mortality risk (in the form of relative hazards) was the primary outcome. Additional tests of mediators and moderators ascertained whether associations between personality and mortality risk remained significant when psychosocial and behavioral variables were statistically controlled. RESULTS: The findings, including a new 14-year additional follow-up in old age, revealed that conscientiousness, measured independently in childhood and adulthood, predicted mortality risk across the full life span. The link from childhood remained robust when adult conscientiousness and certain behavioral variables were controlled. Psychosocial and behavioral variables partly explained the adult conscientiousness-longevity association. CONCLUSION: The findings demonstrate the utility and complexity of modern personality concepts in understanding health and point to conscientiousness as a key underexplored area for future biopsychosocial studies.
