Personality and Health, Subjective Well-Being, and Longevity

ABSTRACT Personality traits can be employed to guide understanding of trajectories to health and longevity, but long-term longitudinal study and multifaceted assessment of healthy aging are crucial. Following up on the life span study initiated by Lewis Terman, we assessed 4 validated factors of personality in young adulthood in 1940, constructed a multifactor measure of participants' healthy aging in 1986, and collected death certificates through 2007 (to determine longevity) on a sample of 1,312 Terman participants (732 men). Neuroticism predicted worse physical health and subjective well-being in old age and, for women, higher mortality risk, but for men, neuroticism predicted decreased mortality risk. For both sexes, extraversion predicted old-age social competence, whereas conscientiousness predicted men's old-age productivity. Differential patterns of association between personality traits and healthy aging components are informative about individual personality characteristics and long-term health outcomes.     

Intergenerational relationships and marriage in China: Within-family longitudinal associations and between-family differences

Marriage is embedded in the web of spouses' broader social ties, and relationship quality with parents and parents-in-law is associated with marital quality. Guided by Family Systems theory and using three waves of dyadic data from 268 Chinese different-sex couples across the first several years of marriage, we first conducted a Random-Intercept Actor-Partner Interdependence Cross-lagged Panel Model (RI-APIM-CLPM) to examine the within-family longitudinal associations among husbands' and wives' relationship quality with parents, parents-in-law, and spouse. Then, husbands' and wives' filial obligations were added as predictors of between-family differences in their own and their partner's relationship quality in the three social ties. Among husbands, increased relationship quality in one social tie (e.g., with parents) predicted reductions in relationship quality in the other social ties (e.g., relationships with parents-in-law and marital quality). Our examination of between-family differences demonstrated that high levels of filial obligations predicted higher intergenerational relationship quality and marital quality. By simultaneously considering the within-family associations of multiple social ties and how filial obligations account for between-family differences in relationship quality, we contribute to a nuanced understanding of how Chinese couples' romantic partnerships are embedded in their broader family system.     

Prospective associations from family-of-origin interactions to adult marital interactions and relationship adjustment.

To test the social learning-based hypothesis that marital conflict resolution patterns are learned in the family of origin, longitudinal, observational data were used to assess prospective associations between family conflict interaction patterns during adolescence and offspring's later marital conflict interaction patterns. At age 14 years, 47 participants completed an observed family conflict resolution task with their parents. In a subsequent assessment 17 years later, the participants completed measures of marital adjustment and an observed marital conflict interaction task with their spouse. As predicted, levels of hostility and positive engagement expressed by parents and adolescents during family interactions were prospectively linked with levels of hostility and positive engagement expressed by offspring and their spouses during marital interactions. Family-of-origin hostility was a particularly robust predictor of marital interaction behaviors; it predicted later marital hostility and negatively predicted positive engagement, controlling for psychopathology and family-of-origin positive engagement. For men, family-of-origin hostility also predicted poorer marital adjustment, an effect that was mediated through hostility in marital interactions. These findings suggest a long-lasting influence of family communication patterns, particularly hostility, on offspring's intimate communication and relationship functioning.     

Examination of Gender Differences in Modeling OCBs and Their Antecedents in Business Organizations in Taiwan

This research presents a model of organizational citizenship behaviors (OCBs) mediated by social network ties using gender as a moderator. In the proposed model, OCBs are influenced indirectly by the need for power-prestige, outcome interdependence, and person-organization fit through the mediation of instrumental ties and expressive ties, which are considered social network ties. Gender moderates several paths in the model. The moderating effects of gender are simultaneously examined using data collected in Taiwan. Test results show that the influence of the need for power-prestige on expressive ties is stronger for women than for men, and the influence of the need for power-prestige on instrumental ties is stronger for men than for women. Moreover, the influence of outcome interdependence on instrumental ties is stronger for men than for women. Finally, detailed findings and their implications are discussed.     

Children,traditionalism in the division of family work,and marital satisfaction: “What's love got to do with it?”

This research examines several of the factors related to the frequently cited finding that the presence of children in the home is related to lower marital satisfaction. Structural equation modeling was used to test whether the number of children at home and the length of marriage predicted traditionalism in the division of family work, which, in turn, was differentially associated with erotic, ludic, friendship-based, and agapic love as well as marital satisfaction for 530 married men and women. For both men and women, the greater the number of children at home and the longer the marriage, the more traditional the division of family labor. Traditionalism predicted lower levels of erotic and friendship-based love for women, which ultimately were related to lower marital satisfaction. For men, however, traditionalism was associated with stronger erotic and friendship-based love, a phenomenon linked to higher marital satisfaction. These findings clarify the connection between the number of children at home and reduced marital satisfaction for the women in the sample and suggest that, for both men and women, it is how family work is divided, rather than the presence of children per se, that has meaning for the affective quality of the marriage.     

Marital adjustment and interleukin-6 (IL-6)

Building on prior research that marital functioning is associated with a variety of health outcomes, we evaluated the association between marital adjustment and a marker of inflammation in a sample of married adults between the ages of 35 and 84 years old (N = 415) from the second wave of the population-based Survey of Midlife Development in the United States (MIDUS II). Specifically, we evaluated associations between positive (i.e., partner support) and negative (i.e., partner strain) dimensions of marital adjustment and interleukin-6 (IL-6) separately for men and women, and whether these associations were moderated by age. Results indicated that (a) marital adjustment was not associated with IL-6 in men, (b) age moderated the association between marital adjustment and IL-6 in women, (c) partner support and partner strain were associated with IL-6 in younger women, and (d) partner support but not partner strain was uniquely associated with IL-6 in younger women. The associations between marital adjustment and IL-6 in younger women were significant when controlling for demographic variables, health status indicators, health behaviors, depressive symptoms, and perceived stress. These findings suggest that IL-6 may be a useful biomarker for studying health-relevant biological responses within intimate relationships, and that young women, in particular, may exhibit increased inflammation when partner support is low.     

The association of childhood intelligence with mortality risk from adolescence to middle age: Findings from the Aberdeen Children of the 1950s cohort study

There is growing evidence that childhood IQ is inversely associated with mortality in later life. However, the specificity of this association in terms of causes of death, whether it is continuous over the whole range of IQ scores and whether it is the same according to age and sex is not clear. In a large cohort (N = 11,603) of a complete population of children born in one city in the UK in the early 1950s, IQ measured at age 7 years (using a routinely administered picture test) was found to be inversely associated with mortality between the ages of 15 and 57 years. For every 1 SD increase in IQ at 7, the all cause mortality hazard ratio was 0.79 (95% CI 0.73, 0.85). On adjustment for a range of perinatal factors, father's social class at birth, number of sibs in the household and childhood height and weight, this was attenuated slightly to 0.81 (0.74, 0.88). Almost identical associations of IQ with mortality were seen for men and women as well as at younger (15–39) and older (40+) ages. These associations were across the entire IQ range, although some of the high mortality in the lowest category of IQ (< 70) was accounted for by causes associated with congenital disorders. Overall, external causes of death showed the strongest association, with weaker associations being seen for cancer. Further work is required to understand the mechanisms whereby childhood IQ has such a robust association with mortality in later life.     

Searching under the streetlight?: Age biases in the personal and family relationships literature

Two studies addressing age biases in research on family and social relationships are presented. Study 1 involved a content analysis of nearly 1,000 empirical studies published in six major journals from 1994 to 1999. Studies in these journals generally were limited to samples of adults under the age of 45, though nearly one third of the studies failed to include information about the ages of adult participants. Most research focused on marital ties, romantic partnerships, or relationships between parents and young children. Study 2 (N = 186) assessed beliefs about the importance of various relationships to adults of different ages. Researchers who study relationships (n = 71), adults with advanced degrees in other fields (n = 57), and less–educated adults (n = 58) rated the importance of various social ties to themselves and to adults of different ages. In general, participants agreed that adults of different ages value different social ties. Less–educated individuals rated many social ties as more important than did researchers who study relationships, however. Age biases in sampling and the types of relationships that receive research attention are discussed.     

Reproductive behavior and personality traits of the Five Factor Model

We examined associations between Five Factor Model personality traits and various outcomes of reproductive behavior in a sample of 15 729 women and men from the Wisconsin Longitudinal Study (WLS) and Midlife Development in the United States (MIDUS) survey. Personality and reproductive history was self‐reported in adulthood (mean age: 53 years). High extraversion, high openness to experience, and low neuroticism were associated with larger number of children in both sexes, while high agreeableness and low conscientiousness correlated with larger offspring number in women only. These associations were independent of marital status. There were also more specific associations between personality and timing of childbearing. The findings demonstrate that personality traits of the Five Factor Model are systematically associated with multiple reproductive outcomes. Copyright © 2011 John Wiley & Sons, Ltd.     

Gender differences in the development of depression

The present study attempted to examine possible gender differences in the vulnerability to depression, specifically with regard to eliciting factors, marital status, age of onset, season of hospitalization, and type of treatment. The records of all patients (67 women and 34 men), treated during 1991 for major depression, dysthymia, or depression NOS at a psychiatric hospital in Southeastern Sweden were examined, and placed in empirically derived categories regarding eliciting factors.
The results indicated significant gender differences with regard to eliciting factors, marital status, and age. The eliciting factor in female depression was most commonly "threat to social bonds" whereas in male depression it was "threat to self esteem" or "threat to self respect". Married women were more prone to depression than were married men, as were men living alone compared to women living alone. Women above 60 years of age were significantly more prone to depression than were men of this age group. The results were discussed from two theoretical perspectives: gender role theory and gender-specific developmental theory.     

Marital Conflict and Risk for Child Maladjustment over Time: Skin Conductance Level Reactivity as a Vulnerability Factor

Skin conductance level reactivity (SCLR) was examined as a longitudinal mediator and moderator of relations between parental marital conflict and psychopathology among children and young adolescents. Participants were 157 boys and girls (M age at T1 = 9.31 years; SD = 1.97); there was a 2-year lag between T1 and T2 assessments. At T1, participants' SCLR was assessed in response to lab challenges. Parents completed measures of aggressive marital conflict and child adjustment at T1 and T2. Supportive of moderation effects, T1 marital conflict interacted with T1 SCLR and gender in the prediction of changes in maladjustment. The link between marital conflict and increased internalizing and externalizing symptoms was stronger for girls with higher SCLR than girls with lower SCLR. Marital conflict predicted increased externalizing behaviors for boys with lower SCLR but not higher SCLR, although levels of externalizing behaviors were similar among boys with lower and higher SCLR especially at higher levels of marital conflict. Findings build on the literature by illustrating the importance of examinations of both family risk and youth biological vulnerability for the prediction of psychopathology.     

Relationship Between Social Relations and Mortality of Older Japanese People Living Alone

The association of social relations with mortality was studied over a 54-month period in 535 older Japanese people living alone. Sex-specific proportional hazard analyses indicated that finding it difficult to establish and maintain relationships with other people was significantly related to mortality, regardless of age, general health status, history of health management, psychological conditions, or economic status. The adjusted hazard ratio for finding relations with other people difficult was 4.61 [95% confidence interval (CI): 1.39–15.30] for men and 4.56 (95% CI: 2.19–9.48) for women. The adjusted hazard ratio for nonparticipation in social activities was 1.45 (95% CI: 0.42–4.97) for men and 1.72 (95% CI: 0.70–4.22) for women and did not reach statistical significance. On the other hand, there was a gender difference in the direction of the association between a low-level contact with children, siblings, or other relatives and mortality, for which the adjusted hazard ratio was 3.16 (95% CI: 0.94–10.62) for men and 0.51 (95% CI: 0.27–0.97) for women. These results suggest the need to create a different model for the relationship between social relations and mortality for men and for women living alone.     

Relations between neighborhood factors, parenting behaviors, peer deviance, and delinquency among serious juvenile offenders

The present study examined relations among neighborhood structural and social characteristics, parenting practices, peer group affiliations, and delinquency among a group of serious adolescent offenders. The sample of 14-18-year-old boys (N=488) was composed primarily of economically disadvantaged, ethnic-minority youth living in urban communities. The results indicate that weak neighborhood social organization is indirectly related to delinquency through its associations with parenting behavior and peer deviance and that a focus on just 1 of these microsystems can lead to oversimplified models of risk for juvenile offending. The authors also find that community social ties may confer both pro- and antisocial influences to youth, and they advocate for a broad conceptualization of neighborhood social processes as these relate to developmental risk for youth living in disadvantaged communities.     

Symptoms of Attention-Deficit/Hyperactivity Disorder and Social and School Adjustment: The Moderating Roles of Age and Parenting

This study examined the associations between symptoms of attention-deficit/hyperactivity disorder (ADHD) and social and school adjustment (academic performance, peer relationships, school social problems) and the moderating roles of children’s age and maternal parenting (affection and overprotection) in these associations. The sample consisted of 2,463 students who were in the first to ninth grade in northern Taiwan. Results from the linear mixed models demonstrated that ADHD symptoms were inversely associated with academic performance and positively associated with social adjustment problems. Further, children’s age and maternal parenting moderated the associations between ADHD symptoms and school and social adjustment. For example, maternal overprotection moderated the relation between hyperactivity and negative peer relationships (i.e., difficulty forming and maintaining friendships), such that this relation was stronger for children who experienced higher levels of overprotection than children who did not. Moreover, children’s age moderated the association between attention problems and decreased academic performance, such that this association was stronger for older children and adolescents than for younger children. Furthermore, children’s age and maternal affection interacted to influence the association between attention problems and school social problems (i.e., bullying, aggression, and peer rejection) with maternal affection acting as a buffer for older children (grades 4–6) only. These findings are discussed from a developmental psychopathology perspective.     

Correlates and Prognosis in Relation to Participation in Social Activities Among Older People Living in a Community in Osaka, Japan

To examine the factors associated with social participation and to determine whether social participation is predictive of mortality, a cohort of 1405 randomly selected older people aged 65 years and over, living in Settsu, Osaka Prefecture, was followed up for 66 months. By multivariate analysis using logistic regression, female sex, older age, disability, medical treatment, no use of health checks, no daily preventive health practices, and no life worth living (no Ikigai) were independent risk factors for no participation in social activities. From the analysis using the Kaplan–Meier method, the cumulative survival rates were higher among those who took part in social activities than among those who did not in both age groups, 65–74 years and 75 years and older, for men and women. Application of the Cox proportional hazards model resulted in adjusted hazard ratio of no participation in social activities for mortality of 1.53 (95% confidence interval: 1.11–2.11), controlling for other potential factors. These results suggest that participation in social activities is closely associated with health and psychosocial conditions and may be an independent risk factor for mortality among community-residing older people.     

Social role and birth cohort influences on gender-linked personality traits in women: a 20-year longitudinal analysis

Growth curve modeling was used to examine the impact of social role experiences (e.g., marital support, occupational prestige) and birth cohort on mean-level differences and age-related changes in positive personality traits indicative of either femininity or masculinity in 758 mothers heterogeneous in age, assessed 4 times over 2 decades. Both femininity and masculinity increased significantly from mean ages 39 through 59; each was predictive of an age change in the other. Low masculinity was associated with a more rapid increase in femininity, whereas high occupational prestige decreased the magnitude of association between masculinity and femininity. Femininity increased with more marital support but decreased with unmarried status, more children at home, and working full or part time; among full-time workers, that effect was modified by marital support. Masculinity increased with full-time work and high occupational prestige. A trend for differing levels of femininity, and contrasting associations of masculinity with femininity and marital conflict in women born after 1944 compared with those born earlier, suggests shifting social norms and gender relations in the marital role.     

DETERMINANTS AND CONSEQUENCES OF CREATIVITY IN A COHORT OF GIFTED WOMEN

Forty women who had been selected by Lewis Terman in 1921 for his study of intellectually gifted California school children were reinterviewed in 1987 (Mean = 77 years, SE±1). These women had been prospectively followed by questionnaire over the intervening 65 years. Their capacity for creativity–putting something in the world that was not there before–was assessed by review of their prospectively gathered questionnaires and by retrospective interview. The 20 women viewed as most creative (usually for literary publication, art, music, or starting an organization) were more likely in the past to have manifested generativity, and at the present to have adjusted well to old age. Although the ego defenses of sublimation, humor, and altruism were more frequent among the creative women, no differences were noted in the happiness of their childhoods or their mental health prior to the present.     

Pink for Girls,Red for Boys,and Blue for Both Genders: Colour Preferences in Children and Adults

Colours carry social connotations like pink for girls and blue for boys. In a cross-sectional study, we investigated whether such early gender coding might be reflected in absolute colour preferences in children and adults of both genders. In two studies, participants selected their favourite (and least favourite, Study 2) colour from an unrestricted sample of colours. We tested 129 Swiss children (Study 1, 10–14 years-old, 68 boys) and 180 Swiss adults (Study 2, 17–48 years-old, 88 men). In children, we observed that girls chose pink/purple as their favourite hue more often than boys did, the most common favourite hue in girls and boys was blue, and boys chose red as their favourite more often than girls did. In adults, we observed that both genders almost never choose pink as their favourite, blue was a common favourite colour, and women were more likely to favour red than were men. In an additional study (n?=?183 Swiss participants, 47 men), we tested whether liking of pink, blue, and red was related to emotion associations with these colours. Pink was associated with positive emotions to the same extent as blue and red. Women further associated more positive emotions with pink than did men. We conclude that some commonalities (blue) and gender differences (pink and red) exist in absolute colour preferences. These differences, however, cannot be fully accounted by emotional associations. We speculate about these gendered colour preferences in relation to gender stereotypes and status differences between men and women.

     

Parent-to-child physical aggression,neighborhood cohesion,and development of children's internalizing and externalizing

Taking a risk and resilience approach, this study examined (1) whether child age moderates the association between exposure to parent–child physical aggression (PCPA) and initial levels and growth in internalizing and externalizing problems, and (2) whether neighborhood social cohesion is a protective factor for children who experience PCPA. Data came from 2810 caregivers of children aged 3–15 who participated in the Project on Human Development in Chicago Neighborhoods (PHDCN). Multilevel growth models showed that age moderated PCPA's association with internalizing problems, such that the association was stronger in older children than in younger children. Age also moderated PCPA's association with externalizing problems, such that the association was stronger in younger children than in older children. Neighborhood cohesion partially attenuated the association between PCPA and internalizing but only for older children; living in a neighborhood characterized by high cohesion mitigated levels of internalizing for maltreated children aged 11 years and older.     

An examination of the differential relationship of marital discord to parents' discipline strategies for boys and girls

Previous research has tentatively indicated that coercive, ineffective parenting might have a mediating role in the differential impact of marital discord on boys and girls. To further explore this role, we examined the relationship between children's perceptions of marital discord and their evaluations of parental discipline techniques. Ninety-one children aged 8 to 13 years (mean age: 11 years 4 months) were split into high, moderate, and low perceived marital discord on the basis of their responses to the Children's Perceptions Questionnaire (Emery & O'Leary, 1982). The children rated how coercive they believed both mothers and fathers would and should be in three discipline situations. Children with high marital discord indicated that both mothers and fathers would and should use more coercive behavior than did children with low marital discord. The effects of marital discord were stronger for boys than for girls. All children also believed that fathers would and should be more coercive than mothers. Results are discussed in relation to the effects of marital discord on children's social development with regard to sex of the child.Thanks are due to Mike Siegal and Pat Noller for their helpful comments on previous drafts.
