Family support, family income, and happiness: a 10-year perspective.

This study examined the role of 2 central aspects of family life--income and social support--in predicting concurrent happiness and change in happiness among 274 married adults across a 10-year period. The authors used hierarchical linear modeling to investigate the relationship between family income and happiness. Income had a small, positive impact on happiness, which diminished as income increased. In contrast, family social support, measured by 3 subscales, Cohesion, Expressiveness, and Conflict, showed a substantial, positive association with concurrent happiness, even after controlling for income. Furthermore, family income moderated the association between family social support and concurrent happiness; family social support was more strongly associated with happiness when family income was low than when family income was high. In addition, change in family social support was positively related to change in happiness, whereas change in family income was unrelated to change in happiness. These findings suggest that happiness can change and underscore the importance of exploring more deeply the role that family relationships play in facilitating such change.

Self-verification 360°: Illuminating the Light and Dark Sides

Self-verification theory assumes that people actively work to preserve their self-views, even if these self-views are negative. This article considers the benefits and drawbacks of receiving self-verification. Direct benefits of self-verification include psychological coherence, reduced anxiety, and improved health. Indirect benefits include greater intimacy and trust in relationships and more harmonious social interactions. Drawbacks of self-verification strivings are limited to people with negative self-views, who may find that self-verifying evaluations help perpetuate low self-esteem and depression and stabilize unhealthy relationships. Elucidating the processes underlying self-verification may bring more light to its dark side; specifically, it may reveal insights about raising self-esteem and building happiness.

Depression and vulnerability to incident physical illness across 10 years.

BACKGROUND While considerable research exists on the role of physical illness in initiating depressive reactions, the role of depression in the onset of physical illness is much less studied. Moreover, whereas almost all previous research on depression and incident physical illness has involved specific physical illnesses, the present study examines the link between depression and incident physical illness more generally. METHODS The study followed 388 clinically depressed patients who were entering treatment for unipolar depressive disorders and 404 matched community controls across 10 years. In self-report surveys, sociodemographic and health behavior data were indexed at baseline and physician-diagnosed medical conditions were indexed at baseline and at 1, 4, and 10 years during the follow-up period. RESULTS After accounting for prior physical illness and key demographic and health behavior factors, membership in the depressed group was significantly linked to physical illness during the follow-up period. In these prospective analyses, depressed patients showed an almost two-thirds higher likelihood of experiencing physical illness during the follow-up period compared to community controls. The prospective association between depression and subsequent physical illness was evident for both less serious and more serious physical illness. LIMITATIONS Although participants were asked to report only physician-diagnosed conditions, the association between depression and physical illness may have been due to depressed individuals perceiving themselves as more ill than they were. CONCLUSIONS The World Health Organization has included the co-morbidity between depression and chronic physical illness among its ten concerns in global public health. The current findings broaden the growing awareness of the co-morbidity between depression and physical illness to encompass a vulnerability of depressed individuals to physical illness more generally.

Smoking Status, Physical Health–Related Quality of Life, and Mortality in Middle-Aged and Older Women

INTRODUCTION Women who smoke, particularly older women, have been relatively neglected in smoking research. There is a lack of knowledge concerning the relation of level of smoking to quality of life and mortality among middle-aged and older women smokers. METHODS This study examined the relation of smoking status to physical health-related quality of life (PHRQL) and total mortality in women in the Womens Health Initiative (WHI) Observational Study. Participants were 90,849 postmenopausal women, who were an average age of 63.6 years at baseline. Analyses used multiple linear and Cox proportional hazards regression and controlled for age, educational level, and ethnicity. Never-smokers were the reference group. RESULTS We found that smoking status was significantly related to PHRQL cross-sectionally at baseline and prospectively at a 3-year follow-up, with those who smoked having lower PHRQL. Heavier smokers showed large, clinically meaningful associations with PHRQL and light smokers showed small associations. In addition, we found that the smoking status at baseline was significantly related to 10-year total mortality. Both light and heavier smoking at baseline significantly correlated with higher mortality risk; however, the relationship of smoking to mortality was dose dependent. Among former smokers, those who had smoked longer showed significantly lower PHRQL and significantly increased mortality risk. CONCLUSIONS Findings suggest that the risks of smoking may not be evident to light smokers and that educational interventions targeted to middle-aged and older women stressing the consequences of light smoking may be particularly beneficial.

Social influences on smoking in middle-aged and older women

The purpose of this study was to examine the role of 2 types of social influence--general social support and living with a smoker--on smoking behavior among middle-aged and older women in the Womens Health Initiative (WHI) Observational Study. Participants were postmenopausal women who reported smoking at some time in their lives (N=37,027), who were an average age of 63.3 years at baseline. Analyses used multiple logistic regression and controlled for age, educational level, and ethnicity. In cross-sectional analyses, social support was associated with a lower likelihood and living with a smoker was associated with a higher likelihood of being a current smoker and, among smokers, of being a heavier smoker. Moreover, in prospective analyses among baseline smokers, social support predicted a higher likelihood and living with a smoker predicted a lower likelihood of smoking cessation 1-year later. Further, in prospective analyses among former smokers who were not smoking at baseline, social support predicted a lower likelihood and living with a smoker predicted a higher likelihood of smoking relapse 1-year later. Overall, the present results indicate that social influences are important correlates of smoking status, smoking level, smoking cessation, and smoking relapse among middle-aged and older women.

Purposiveness and Leisure-Time Physical Activity in Women in Early Midlife

Physical activity in early midlife has important implications for womens health. The present cross-sectional study investigated the relation of purposiveness to leisure-time physical activity, as mediated by health investment, in a sample of women in early midlife. Participants were 211 women between the ages of 35 and 45 years (mean 40.55 years, SD = 3.11) who responded to the second wave of the study of Midlife Development in the United States. Participants were originally selected by means of a nationally representative random-digit-dialing procedure. A structural equation analysis of data with latent variables was conducted with MPLUS. Purposiveness was indexed by measures of purpose in life, personal growth, and future planning. Health investment was indexed by thought and effort committed to health and the extent to which individuals worked hard to stay healthy. Leisure-time physical activity was indexed by both moderate and vigorous leisure-time activity. Results, controlling for sociodemographic factors, showed that purposiveness was associated with more physical activity and that the relation between purposiveness and leisure-time physical activity was fully mediated by health investment. These results suggest that women with a sense of purpose may be better able to achieve acceptable levels of physical activity.

Depressive symptoms and cigarette smoking in American workers.

Purpose. This study examined the relationship between depressive symptoms and cigarette smoking in a large sample of American workers. Methods. We used data from the National Survey of Midlife Development in the United States. Seventy percent of individuals completed a telephone survey. The present study focused on 2593 individuals working for pay. Measures included depressive symptoms, job level, and current smoking status. Results. In a logistic regression analysis, depressive symptoms significantly predicted smoking status among workers (p < .01). In follow-up x2 analyses, the link between depressive symptoms and smoking was consistent across gender (p < .01) and job levels (p < .01). Discussion. Depressive symptoms among workers present an underlying obstacle to the success of worksite smoking cessation efforts. Findings highlight the need for increased cooperation between workplace mental health and medical health promotion programs and for tailoring smoking cessation programs to depressed workers. Limitations include self-report cross-sectional data and an underrepresentation of minority group members and individuals of low socioeconomic status.

Longitudinal Change in Happiness during Aging: The Predictive Role of Positive Expectancies

This study employed hierarchical linear modeling to document the time course of happiness across 20 years from average ages of 66 to 86 among 717 members of the Terman Study of the Gifted. In addition, the study examined the role of positive expectancies about aging, assessed at an average age of 61, in enhancing happiness in aging. The results showed a small decline in happiness over time. Higher age was associated with less happiness at baseline and with a greater decline in happiness. At the same time, the general level of happiness in this sample was moderately high, with a large majority of respondents relatively happy into later aging. Moreover, positive expectancies about aging, assessed at an average age of 61, predicted greater happiness at ages 70, 75, and 80. These results held controlling for prior happiness, as well as for prior self-rated health and income.

The Language of Psychological Change: Decoding an Expressive Writing Paradigm

This study uses linguistic analysis to investigate psychological changes associated with an emotion regulation strategy integrating psychological acceptance and positive reappraisal, as compared to two established strategies. Two hundred and sixty-nine undergraduate participants wrote for 4 consecutive days, 20 minutes each day, about the biggest problem in their lives and were randomly assigned to use one of three emotion regulation strategies: (a) acceptance + positive reappraisal, (2) emotional disclosure, or (3) positive reappraisal. Linguistic analyses were conducted to examine changes in attentional focus and insightful and causal thinking in the writings. Results indicated that participants who integrated acceptance and positive reappraisal wrote less about the past and more about the future, and used more insight words, over the course of writing relative to the other two conditions. In addition, they used a decreasing amount of first-person singular pronouns (e.g., “I”) and increased more in their use of first-person plural pronouns (e.g., “we”). Implications of these language findings for understanding underlying psychological changes are discussed.

Finding happiness in negative emotions: An experimental test of a novel expressive writing paradigm

Using an experimental writing design, this study pitted a novel emotion regulation strategy, integrating psychological acceptance and positive reappraisal, against two established strategies for increasing psychological well-being: emotional disclosure (Pennebaker, 1997) and positive reappraisal (DeNeve & Cooper, 1998; Gross & John, 2003). 315 undergraduate students wrote on four consecutive days about the biggest problem in their lives and were randomly assigned to use one of the three strategies: (1) emotional disclosure, (2) positive reappraisal, or (3) acceptance + positive reappraisal. Results indicated that the integrative condition led to optimal emotional well-being outcomes at post-intervention, including: greater happiness and positive emotions, marginally fewer negative emotions, and greater overall psychological acceptance. Findings indicate that accepting ones negative emotions and then trying to seek out positives might be an optimal strategy for building happiness.
