Predicting relationship and life satisfaction from personality in nationally representative samples from three countries: The relative importance of actor, partner, and similarity effects.

Three very large, nationally representative samples of married couples were used to examine the relative importance of 3 types of personality effects on relationship and life satisfaction: actor effects, partner effects, and similarity effects. Using data sets from Australia (N = 5,278), the United Kingdom (N = 6,554), and Germany (N = 11,418) provided an opportunity to test whether effects replicated across samples. Actor effects accounted for approximately 6% of the variance in relationship satisfaction and between 10% and 15% of the variance in life satisfaction. Partner effects (which were largest for Agreeableness, Conscientiousness, and Emotional Stability) accounted for between 1% and 3% of the variance in relationship satisfaction and between 1% and 2% of the variance in life satisfaction. Couple similarity consistently explained less than .5% of the variance in life and relationship satisfaction after controlling for actor and partner effects.

Safety at work: A meta-analytic investigation of the link between job demands, job resources, burnout, engagement, and safety outcomes.

In this article, we develop and meta-analytically test the relationship between job demands and resources and burnout, engagement, and safety outcomes in the workplace. In a meta-analysis of 203 independent samples (N = 186,440), we found support for a health impairment process and for a motivational process as mechanisms through which job demands and resources relate to safety outcomes. In particular, we found that job demands such as risks and hazards and complexity impair employees' health and positively relate to burnout. Likewise, we found support for job resources such as knowledge, autonomy, and a supportive environment motivating employees and positively relating to engagement. Job demands were found to hinder an employee with a negative relationship to engagement, whereas job resources were found to negatively relate to burnout. Finally, we found that burnout was negatively related to working safely but that engagement motivated employees and was positively related to working safely. Across industries, risks and hazards was the most consistent job demand and a supportive environment was the most consistent job resource in terms of explaining variance in burnout, engagement, and safety outcomes. The type of job demand that explained the most variance differed by industry, whereas a supportive environment remained consistent in explaining the most variance in all industries.

Relationship of daily hassles, uplifts, and major life events to health status.

100 45–64 yr olds completed a hassles scale, an uplifts scale, a recent life events schedule, and a health status questionnaire. Analysis showed that hassles—the repeated or chronic strains of everyday life—were more strongly associated with somatic health than were life events. Hassles shared most of the variance in health that could be accounted for by life events, and when the effects of life events were statistically removed, hassles and health remained significantly related. Daily uplifts made little contribution to health that was independent of hassles. The assessment of daily hassles appears to be a useful approach to the study of life stress and could be an important supplement to the life events approach that, alone, is insufficient for full understanding and practical prediction of health outcomes.

Impact of health beliefs, quality of life, and the physician-patient relationship on the treatment intentions of inflammatory bowel disease patients.

The research tested a model of treatment decision making in chronic illness that includes health beliefs, quality of life, and relationship with the physician (shared or not). Inflammatory bowel disease patients, (N=218) reported on their physician-patient relationship, general and disease-specific quality of life, and intentions to take a drug, for which perceived benefits and costs were manipulated. For more symptomatic patients, both costs and benefits predicted intentions; however, for less symptomatic patients, costs played a more important role. Physician recommendation predicted intention primarily among those who shared a decision-making relationship with their physician. Overall, the model accounted for 57.8% of the variance in medication-taking intention. Findings suggest that an integrative consideration of relationship factors, health beliefs, and health status may help explain treatment intentions among the chronically ill.

The costs and benefits of writing, talking, and thinking about life's triumphs and defeats.

Three studies considered the consequences of writing, talking, and thinking about significant events. In Studies 1 and 2, students wrote, talked into a tape recorder, or thought privately about their worst (N = 96) or happiest experience (N = 111) for 15 min each during 3 consecutive days. In Study 3 (N = 112), students wrote or thought about their happiest day; half systematically analyzed, and half repetitively replayed this day. Well-being and health measures were administered before each study's manipulation and 4 weeks after. As predicted, in Study 1, participants who processed a negative experience through writing or talking reported improved life satisfaction and enhanced mental and physical health relative to those who thought about it. The reverse effect for life satisfaction was observed in Study 2, which focused on positive experiences. Study 3 examined possible mechanisms underlying these effects. Students who wrote about their happiest moments--especially when analyzing them--experienced reduced well-being and physical health relative to those who replayed these moments. Results are discussed in light of current understanding of the effects of processing life events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of infant feeding practices and birth spacing on infant and child survival: a reassessment from retrospective and prospective data

Retrospective and prospective data collected in Cameroon were used to reassess hypotheses about how infant and early childhood mortality is affected by birth spacing and breast-feeding. These data show that: (a) a short preceding birth interval is detrimental for child survival in the first 4 months of life; (b) full and partial breast-feeding have direct protective effects on child survival in the first 4-6 months of life, with the effects of the former stronger than those of the latter; (c) early subsequent conception significantly increases mortality risks in the first 16 months of life of the index child. These findings are robust to various controls, e.g. study design, data defects, child's health conditions at/around birth, postnatal maternal and child recurrent illnesses, patterns of utilisation of health care services, and immunisation status of the child.     

Development and validation of a Coping with Discrimination Scale: Factor structure, reliability, and validity.

Four studies were conducted to develop and validate the Coping With Discrimination Scale (CDS). In Study 1, an exploratory factor analysis (N = 328) identified 5 factors: Education/Advocacy, Internalization, Drug and Alcohol Use, Resistance, and Detachment, with internal consistency reliability estimates ranging from .72 to .90. In Study 2, a confirmatory factor analysis (N = 328) provided cross-validation of the 5-factor model as well as evidence for validity of the scale. The validity evidence was similar across racial groups and for males and females. In Study 3, the estimated 2-week test–retest reliabilities (N = 53) were between .48 and .85 for the 5 factors. Education/Advocacy, Internalization, Drug and Alcohol Use, and Detachment were positively associated with active coping, self-blame, substance use, and behavioral disengagement, respectively, providing further support for validity of the CDS. Finally, incremental validity evidence was obtained in Study 4 (N = 220), where it was shown that the CDS explained variance in outcome variables (i.e., depression, life satisfaction, self-esteem, and ethnic identity) that could not be explained by general coping strategies.

Bullying and Victimization in Elementary Schools: A Comparison of Bullies, Victims, Bully/Victims, and Uninvolved Preadolescents.

Research on bullying and victimization largely rests on univariate analyses and on reports from a single informant. Researchers may thus know too little about the simultaneous effects of various independent and dependent variables, and their research may be biased by shared method variance. The database for this Dutch study was large (N=1,065) and rich enough to allow multivariate analysis and multisource information. In addition, the effect of familial vulnerability for internalizing and externalizing disorders was studied. Gender, aggressiveness, isolation, and dislikability were most strongly related to bullying and victimization. Among the many findings that deviated from or enhanced the univariate knowledge base were that not only victims and bully/victims but bullies as well were disliked and that parenting was unrelated to bullying and victimization once other factors were controlled.

Generalized self-efficacy, self-esteem, and negative affect.

In order to help resolve the ongoing debate about the relationship between and the functions of self-esteem and generalized self-efficacy (GSE), the authors tested the hypotheses that GSE predicts future self-esteem and that self-esteem predicts unique incremental variance in future negative affect. Measures of these three constructs were administered to two samples of undergraduates (N = 160 and N = 75) twice over five-six weeks. Time 1 GSE accounted for significant variance in Time 2 self-esteem in both studies, 1.6% of the variance in Study 1 and 4.6% of the variance in Study 2, after controlling for Time 1 self-esteem. Time 1 self-esteem did not predict Time 2 GSE in either study. Self-esteem accounted for significant variance in negative affect in Study 1. Results suggest that GSE and self-esteem are distinct, that GSE may play a role in the development of self-esteem, and that self-esteem may help shape negative affect.

Modeling Error Variance in Job Specification Ratings: The Influence of Rater, Job, and Organization-Level Factors.

The authors modeled sources of error variance in job specification ratings collected from 3 levels of raters across 5 organizations (N=381). Variance components models were used to estimate the variance in ratings attributable to true score (variance between knowledge, skills, abilities, and other characteristics [KSAOs]) and error (KSAO-by-rater and residual variance). Subsequent models partitioned error variance into components related to the organization, position level, and demographic characteristics of the raters. Analyses revealed that the differential ordering of KSAOs by raters was not a function of these characteristics but rather was due to unexplained rating differences among the raters. The implications of these results for job specification and validity transportability are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relationships Among Health Factors and Everyday Problem Solving in African Americans.

This study examined whether measures of health status enhance the prediction of performance on everyday problem solving in adult African Americans. The sample consisted of 209 community-dwelling African American adults with a mean age of 66.82 years (SD=7.95). The following variables were included in the analysis: Everyday Problems Test (EPT), summary index of chronic illnesses (cardiovascular disease, hypertension, arthritis, stroke, and diabetes), self-rated health (current health, health in the past month, health compared with others, health compared with 5 years ago), and demographic information. Using hierarchical regression and follow-up communality analysis, the authors found that the number of chronic illnesses and self-rated health as compared with 5 years prior were significant and unique predictors of performance on the EPT but did not account for all of the demographic-related variance. The results indicate that health indices contribute to the variability in everyday cognition in this understudied population. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Health status, perceptions of risk, and prevention interest for health and nonhealth problems.

Studied the effects of acute illness on unrealistic optimism about health and life events in 21 male and 22 female acutely ill college students with relatively minor illnesses. These Ss were compared with 23 male and 44 female healthy participants for response to rating comparative risk and preventability of health and nonhealth life problems such as divorce or auto accident. Healthy Ss were equally optimistic about health and nonhealth expectations, but those who were ill felt much more vulnerable to health problems in the future. It is contended that health centers may not be the optimal site for delivery of health risk reduction materials since those who are ill may have less interest or belief in prevention possibilities.

Health-related Internet use, coping, social support, and health indicators in people living with HIV/AIDS: Preliminary results from a community survey.

Widespread Internet use has revolutionized health information and patient education for persons with chronic illnesses. The authors surveyed 147 HIV-positive persons to examine factors associated with Internet use and associations between Internet use and health. Information, motivation, and behavioral skills associated with using the Internet were related to Internet use. The authors found that health-related Internet use was associated with HIV disease knowledge, active coping, information-seeking coping, and social support among persons who were using the Internet. These preliminary findings suggest an association between using the Internet for health-related information and health benefits among people living with HIV/AIDS, supporting the development of interventions to close the digital divide in HIV/AIDS care.

Identifying Shared Environmental Contributions to Early Substance Use: The Respective Roles of Peers and Parents.

Although behavior genetic studies have suggested that early substance use is primarily environmentally mediated, no study has sought to identify the specific sources of environmental variance. Using data obtained from multiple informants, this study assessed the contributions of peer deviance and parent-child relationship problems to substance use in 14-year-old male and female twins (N = 1,403) drawn from the Minnesota Twin Family Study (MTFS). All three phenotypes were influenced primarily by shared environmental variance (average c2 = .51), as was the overlap among them. Moreover, peer deviance and parent-child relationship problems accounted for approximately 77% of the variance in early substance use. Findings also indicated that peer deviance, but not parent-child relationship problems, accounted uniquely for variance in early substance use.

Being popular can be healthy or unhealthy: Stress, social network diversity, and incidence of upper respiratory infection.

Diverse social contacts are generally associated with better health. However, diverse contacts can increase exposure to infectious agents. This should increase risk for disease, particularly among those whose host resistance is otherwise compromised (e.g., stressed individuals). In this prospective study, healthy college students who completed questionnaires assessing social network diversity and stressful life events were subsequently interviewed weekly for 12 weeks to track incidence of upper respiratory infections (URIs). URI episodes were defined by a symptom criterion and by clinically verified self-reported illness. Stress and diversity of social contacts interacted; diversity was associated with more illnesses among those with more stressful life events and slightly fewer illnesses among those with fewer stressful life events. Associations remained after controlling for neuroticism. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Methods for studying course of illness with severely mentally ill adults

This study examined methods for obtaining course of illness data on adults who are severely mentally ill. A convenience sample (N = 60) was recruited within 4 programs serving different subgroups of adults with severe mental illness. Forty-three participants were able to complete follow-up interviews, using a life chart format to report on personal history in the domains of housing, employment, finances, psychiatric service utilization, health problems, use of psychotropic medication, drug and alcohol use, social relationships, and other major life events. Corresponding information was abstracted from treatment records and examined for concordance with self-reports. Results showed distinct areas of concordance, including recent (1 year) life events, psychiatric care, psychotropic medications, and use of alcohol. Areas of disagreement included legal problems, illicit drug use, and general health. With multiple data sources, it is possible to involve a range of adults with severe mental illness in research and to incorporate their knowledge into course of illness studies.     

Health-related quality of life measured by the SF12 in working populations: Associations with psychosocial work characteristics.

This study investigated the contribution of psychosocial work characteristics (decision latitude, job demand, social support at work, and effort-reward imbalance) to health-related quality of life. Data were derived from 2 aircraft manufacturing plants (N = 1,855) at the start of a longitudinal study. Regression analysis showed that work characteristics (1st model) explained 19% of the variance in the mental summary score of the Short Form-12 Health Survey. R2 change for work characteristics decreased to 13%, accounting for demographics, socioeconomic status, body mass index, and medical condition (5th model). Including health behavior and personality factors (full model), R2 change for work characteristics remained significant. Psychosocial work characteristics account for relevant proportions in the subjective perception of mental health beyond a wide array of medical variables and personality factors.

Marital Adjustment, Child-Rearing Disagreements, and Overreactive Parenting: Predicting Child Behavior Problems.

Using structural equation modeling, the authors evaluated the hypothesis that the relation between marital adjustment and children's behavior problems is mediated by child-rearing disagreements, whose effects are mediated by parents' overreactive discipline. In a community sample, fully or partially mediated models of internalizing and externalizing behavior problems of 3- to 7-year-old boys (N = 99) and girls (N = 104) were supported for mothers and fathers in 7 of 8 cases. Child-rearing disagreements always mediated the relation of marital adjustment and child behavior problems, and overreactive discipline was a final mediator in 3 cases. More variance was accounted for in mothers' than fathers' ratings. For mothers' ratings, the most variance was accounted for in boys' externalizing and girls' internalizing behavior problems.

A comparison of attitude, personality, and knowledge predictors of service-oriented organizational citizenship behaviors.

Attitude, personality, and customer knowledge antecedents were compared in their predictive ability of 3 service-oriented forms of employee organizational citizenship behaviors (OCBs): loyalty, service delivery, and participation. For the 1st study, 236 customer-contact employees provided data concerning their OCBs and the attitude, personality, and knowledge antecedents. The 2nd investigation relied on data provided by 144 contact employees from a network of university libraries. Using hierarchical regression in both studies, the authors found that each of the 3 types of service-oriented OCBs was best predicted by different subsets of the antecedents. Job attitudes accounted for the most unique variance in loyalty OCBs, personality accounted for the most unique variance in service delivery OCBs, and customer knowledge and personality jointly were the best predictors of participation OCBs.

Beyond work and family: A measure of work/nonwork interference and enhancement.

Though early research on the work/nonwork interface was broader in scope, most recent research has focused on the interface between work and family. There is a need for an inclusive, validated measure of work/nonwork interference and enhancement that is appropriate for all workers regardless of their marital or family life status. The authors report here on 3 studies in which they develop a theoretically grounded and empirically validated multidimensional, bidirectional measure of work/nonwork interference and enhancement. All scale items refer to work/nonwork, whereas previous measures have mixed work/family and work/nonwork items or emphasize family roles in the nonwork domain. Quantitative analysis of the scale items yielded 17 items to measure work interference with personal life, personal life interference with work, work enhancement of personal life, and personal life enhancement of work. Confirmatory factor analyses and structural equation modeling results provide evidence for convergent, discriminant, and criterion-related validity for the scale from 2 large samples of workers (N = 540, N = 384) across multiple job types and organizations.
