Physiological Correlates of Volunteering

We review research on physiological correlates of volunteering, a neglected but promising research field. Some of these correlates seem to be causal factors influencing volunteering. Volunteers tend to have better physical health, both self-reported and expert-assessed, better mental health, and perform better on cognitive tasks. Research thus far has rarely examined neurological, neurochemical, hormonal, and genetic correlates of volunteering to any significant extent, especially controlling for other factors as potential confounds. Evolutionary theory and behavioral genetic research suggest the importance of such physiological factors in humans. Basically, many aspects of social relationships and social activities have effects on health (e.g., Newman and Roberts 2013; Uchino 2004), as the widely used biopsychosocial (BPS) model suggests (Institute of Medicine 2001). Studies of formal volunteering (FV), charitable giving, and altruistic behavior suggest that physiological characteristics are related to volunteering, including specific genes (such as oxytocin receptor [OXTR] genes, Arginine vasopressin receptor [AVPR] genes, dopamine D4 receptor [DRD4] genes, and 5-HTTLPR). We recommend that future research on physiological factors be extended to non-Western populations, focusing specifically on volunteering, and differentiating between different forms and types of volunteering and civic participation

Social Relationships and Mortality Risk: A Meta-analytic Review

In a meta-analysis, Julianne Holt-Lunstad and colleagues find that individuals' social relationships have as much influence on mortality risk as other well-established risk factors for mortality, such as smoking

The Role of Time Orientation in Life Satisfaction Across the Life Span

Relating contentment to different points in life can provide the construct of life satisfaction with an essential time orientation. The Self-Anchoring Scale was used to rate life in the present, the past (five years before), and the future (five years ahead). Subjects were the respondents of five national surveys in Israel. The findings showed an age-related configuration where progressive age was associated with declining ratings for the future, a milder decline for the present, and a relative increase for the past. In addition to rating levels, a structural modeling approach was used to explore the relative salience of these time referents, considered as indicators of the construct of life satisfaction. LISREL estimates of the indicator loadings in two related models showed the present as most salient and the past as least salient in most age groups. The salience of the past increased in later life, when that of the future did as well. The time-related construct of life satisfaction (which fit the data in all age groups) highlights the yet undetermined role of the future in the subjective well-being of the elderly. THE need to orient oneself in time is essential to numerousdomains of human functioning (Doob, 1971; Fraisse, 1963). A basic mode of such orientation is the deeply rooted distinction between three time zones: past, present, and future (Cottle & Klineberg, 1974). The concepts of time orientation or time perspective have been designated t

Combining happiness and suffering in a retrospective view of periods of life: A differential approach to subjective well-being.

The intersection of dimensions of subjective well-being (SWB) generates SWB types. We delineated SWB types by cross-tabulating happiness and suffering ratings that participants attributed to outstandingly meaningful periods in their life referred to as anchor periods. A sample of 499 older Israelis (age 58–94) was queried about two positive periods (the happiest, the most important) and two negative periods (the most miserable, the most difficult). A variety of variables discriminated between the more frequent congruous types of Happy (high happiness and low suffering) and Unhappy (low happiness and high suffering), but also presented the incongruous types of Inflated (high happiness and high suffering) and Deflated (low happiness and low suffering) as discriminable. Thus, women were more likely to be Inflated whereas men were more likely to be Deflated; low education related more to Happy in the happiest period and to Unhappy in the negative periods; present life satisfaction related more to Happy than to Unhappy in the positive, but not in the negative, periods; and Holocaust survivors were more likely to be Deflated and Unhappy in the negative, but not in the positive, periods. The study supported a differential perspective on SWB within people’s narratives of their lives

Optimizing well-being: The empirical encounter of two traditions

Subjective well-being (SWB) is evaluation of life in terms of satisfaction and balance between positive and negative affect; psychological well-being (PWB) entails perception of engagement with existential challenges of life. The authors hypothesized that these research streams are conceptually related but empirically distinct and that combinations of them relate differentially to sociodemographics and personality. Data are from a national sample of 3,032 Americans aged 25–74. Factor analyses confirmed the related-but-distinct status of SWB and PWB. The probability of optimal well-being (high SWB and PWB) increased as age, education, extraversion, and conscientiousness increased and as neuroticism decreased. Compared with adults with higher SWB than PWB, adults with higher PWB than SWB were younger, had more education, and showed more openness to experience. Research on well-being has flourished in recent decades (Diener, Suh, Lucas, & Smith, 1999; Kahneman, Diener, & Schwarz, 1999), with increasing recognition of the different streams of inquiry guiding this broad domain. Ryan and Deci’s (2001) integrative review organized the field of well-being into two broad traditions: one dealing with happiness (hedonic well-being), an

Formal Education Level Versus Self-Rated Literacy as Predictors of Cognitive Aging

OBJECTIVES. To compare the prediction of cognitive functioning by formal education and self-rated literacy and the differences in prediction across younger and older cohorts. METHOD. Data on 28,535 respondents were drawn from a cross-sectional representative sample of community-dwelling older individuals (≥50), participating in the Survey of Health, Ageing, and Retirement in Europe. Education level was classified according to the International Standard Classification of Education 1997 (ISCED-1997) self-rated literacy was determined by having respondents rate their reading and writing on 1–5 scales. Cognitive functioning was measured by verbal recall, word fluency, and arithmetic ability. RESULTS. Structural equation modeling demonstrated that self-rated literacy was more strongly associated with cognitive functioning than was education level, with or without additional exogenous variables (age, sex, household income, medical conditions, activities of daily living, reading eyesight, and country). The association between education level and cognitive functioning was weaker in older than in younger age groups, whereas the association between self-rated literacy and cognitive functioning showed the opposite trend. DISCUSSION. Self-rated literacy was found to be a better predictor of late-life cognitive functioning than was the level of formal education. The results have implications for studies of age-related differences in which education level is taken into account
