Gender Convergence in the American Heritage Time use Study (AHTUS)

The present study explored the short-term temporal characteristics of subjective well-being (SWB) and its potential correlates. Specifically, we examined the intra-individual variability and the trajectories of SWB and its components life satisfaction, positive, and negative affect. Over a two-week period, 27 participants (78% university students, 85% females, mean age of 29 years) provided SWB data every other day. Before and after this period, participants completed several questionnaires assessing personality and environmental variables, as well as several open-ended questions. The results provide evidence that participants experienced a significant amount of intra-individual variability in their SWB and its components. Furthermore, inter-individual differences in the intra-individual variability were related to several of the personality and environmental variables, as well as to participant’s age. Results of multiple regression analyses indicated that deliberation (one facet of the Big Five dimension conscientiousness), social support, and age accounted for 58% of the total variance of intra-individual variability in SWB. In contrast, the slopes of the individual trajectories of SWB were on average statistically non-significantly different from zero. These results emphasize that information is gained by looking at both the patterns and the intra-individual variability over time: The individual trajectories of the participants on average appeared to be stable, but intra-individual variability of SWB was meaningfully related to several of the variables.     

A Theory of Life Satisfaction Dynamics: Stability,Change and Volatility in 25-Year Life Trajectories in Germany

An adequate theory of life satisfaction (LS) needs to take account of both factors that tend to stabilise LS and those that change it. The most widely accepted theory in the recent past—set-point theory—focussed solely on stability (Brickman and Campbell, in: Appley (ed) Adaptation level theory, Academic Press, New York, pp 287–302, 1971; Lykken and Tellegen in Psychol Sci 7:186–189, 1996). That theory is now regarded as inadequate by most researchers, given that national panel surveys in several Western countries show that substantial minorities of respondents have recorded large, long term changes in LS (Sheldon and Lucas in The stability of happiness, Elsevier, Amsterdam, 2014). In this paper we set out a preliminary revised theory, based mainly on analysis of the LS trajectories of the 2473 respondents in the German Socio-Economic Panel who reported their LS for 25 consecutive years in 1990–2014. The theory entails three sets of propositions in which we attempt to account for stability, change and also volatility. First, it is proposed that stability is primarily due to stable personality traits, and also to parental influence on LS. The second set of propositions indicates that medium and long term changes are due to differences and changes in personal values/life priorities and behavioural choices. Differences in the priority given to pro-social values, family values and materialistic values affect LS, as do behavioural choices relating to one’s partner, physical exercise, social participation and networks, church attendance, and the balance between work and leisure. Medium term change is reinforced by two-way causation—positive feedback loops—between values, behavioural choices and LS. The third set of propositions breaks new ground in seeking to explain inter-individual differences in the volatility/variability of LS over time; why some individuals display high volatility and others low, even though their mean level of LS may change little over 25 years.     

Health and quality of life of older people,a replication after six years

Replicating a survey of 875 people 55 years old or more undertaken in September 1999 throughout the former Northern Interior Health Region (NIHR) of British Columbia, in September 2005 a sample of 656 people completed a 22-page questionnaire. The average age of the respondents was 68, with a range running from 55 to 96 years, and 64% were women. Responses to the SF-36 questionnaire indicated that for male respondents aged 55–64, the mean score for the 8 dimensions was 76.1. This mean was a bit higher than the 74.4 mean of 1999. For male respondents aged 65 and older the mean was 69.0, which was also higher than the 68.3 mean of 1999. For females aged 55–64, the mean score for 8 dimensions was 73.1, versus 73.0 in 1999. For female respondents aged 65 and older, the mean score was 67.0, versus 65.4 in 1999. Based on these mean scores for the 8 dimensions, then, it is fair to say that the overall health status of males and females aged 55 years and older in the region in 2005 was at least as good as (i.e., the same as or better than) that in 1999. Comparing 28 average figures for the 2005 respondents on satisfaction with specific domains of life (e.g., financial security, health, sense of meaning) and three global indicators (satisfaction with life as a whole and with the overall quality of life, and happiness) with those of the 1999 respondents, we found that the scores for the 2005 sample were at least as high as those of the other sample. Thus, it seems fair to say that the perceived quality of life of older people in the former NIHR so far as it is revealed in domain and global satisfaction and happiness scores, is at least as good as the perceived quality of life of a similar sample in 1999. Although a large majority perceived increases in crime in the 2 year periods prior to both surveys, smaller percentages of the 2005 sample than of the 1999 sample thought that crime had increased over the past two years, avoided going out at night, feared for their safety, had crime-related worries, engaged in crime-related defensive behaviours and were actually the victims of any crimes. Therefore, it seems fair to say that, so far as crime-related issues are concerned for the two samples of seniors responding to our surveys, there is more evidence of improvement than of deterioration. Applying stepwise multiple regression, each of the eight dependent variables was explained on the basis of four clusters of predictors separately and then a final regression was run using only the statistically significant predictors from the four clusters. Broadly speaking, 7 SF-36 health status scales explained from 28% to 45% of the variance in the 8 dependent variables, running from satisfaction with the overall quality of life (28%) to the single item measure of general health (45%). The seven predictors in the Social Relations cluster explained from 7% of the variance in the SF-36 General Health scale scores to 57% of the variance in the Life Satisfaction scores. The four predictors in the Problems cluster explained from 10% of the variance in the SF-36 General Health scale scores to 24% of the variance in the SWLS scores. The 11 predictors in the Domain Satisfaction cluster explained from 14% of the variance in the SF-36 General Health scale scores to 64% of the variance in the SWB scores. Putting all the significant predictors together for each dependent variable, in the weakest case, 4 of 11 potential predictors explained 33% of the variance in the SF-36 General Health scale scores and in the strongest case, 9 of 15 potential predictors explained 70% of the variance in Life Satisfaction scores. Among other things, these results clearly show that respondents’ ideas about a generally healthy life are different from, but not independent of, their ideas about a happy, satisfying or contented life, or about the perceived quality of their lives or their subjective wellbeing. Finally, the 7 core discrepancy predictors of MDT plus incomes were used to explain the eight dependent variables. From 13% of the variance in the SF-36 General Health scale scores to 57% of the variance in SWLS scores was explained using those predictors. Based on an examination of the Total Effects scores for the predictors of the 8 dependent variables, the most influential predictors were Self-Wants, followed by Self-Others and then Self-Best. In other words, the most influential discrepancy predictors of respondents’ overall life assessments were those between what respondents have versus what they want, followed by what they have versus what others of the same age and sex have, and then by what they have versus the best they ever had in the past.

A note of correction with reference to parameters of the menstrual cycle and the efficiency of rhythm methods of contraception

Abstract Owing to a misunderstanding in regard to the data sheets, all the references to the pre- and post-ovulatory phases in Dr. Marshall's data in my paper should be interchanged. The following is a list of conclusions which may be drawn from that study: 1. Although the Farris Test is probably less efficient than had formerly been thought, there is no evidence that it is biased. 2. Within individual histories, pre-ovulatory phase variance usually exceeds post-ovulatory phase variance. 3. The variance of mean pre-ovulatory phase exceeds that of mean post-ovulatory phase among a group of women. 4. Within a group of women, there seems to be no appreciable correlation between mean pre-ovulatory and mean post-ovulatory phase. 5. It is possible that there is a true underlying positive correlation between pre- and post-ovulatory phases within a single menstrual history. 6. The standard error of the RB.T. test was estimated to exceed √6 days. 7. The variances of the phases within individual histories are probably positively correlated, so it seems that in general a variable post-ovulatory phase is not favourable to the outcome of the practice of rhythm.     

A Hybrid Model for Research on Subjective Well-being: Examining Common- and Component-specific Sources of Variance in Life Satisfaction,Positive Affect,and Negative Affect

The primary components of subjective well-being (SWB) include life satisfaction (LS), positive affect (PA), and negative affect (NA). There is little consensus, however, concerning how these components form a model of SWB. In this paper, six longitudinal studies varying in demographic characteristics, length of time between assessment periods, number of assessment periods, and type of measures employed were used to test a hybrid model of SWB comprising both common and component-specific sources of variance. The majority of explained variance in LS was attributable to temporally consistent common variance, rather than component-specific sources. For PA and NA, both common and component-specific sources were substantive and consistent over time. Implications for the conceptualization and operationalizations of SWB are discussed.     

Study on Standard of Population Aging

Do an increase in ageing in developed countries and"getting old before getting rich"in developing countries indicate that f luctuations in the population age structure have produced a qualitative change?What is a qualitative change and what is a quantitative change?Here we propose a new concept of Shadow Population,then establish a new standard for evaluating population age structure,finally present a typical five stage population age structure type transition model.The model simulation shows that all world regions are still in the adult stage and that population ageing belongs to the category of quantitative change.However,sustained low fertility will lead to a qualitative change in the ageing population.The current pressure of population aging in the adult stage placed on the pension security system shows that this system is truly not a sustainable system,Gradually raising the retirement age and Long-term stability in replacement fertility is the key to solving the socioeconomic development dilemma presented by future population ageing in low fertility regions or countries,but the latter is more urgent.     

Verification of the ages of supercentenarians in the United States: Results of a matching study

Unprecedented declines in mortality among the very old have led to the emergence of "true" supercentenarians (persons aged 110 and over). The ages of these individuals have been well-documented in European countries with a history of birth registration, but have not been systematically studied in the United States, which lacks similar documentation and where the inaccuracy of age reporting has been an issue. To verify age, we linked records from the Social Security Administration for close to 700 individuals who died from 1980 to 1999 purportedly at ages 110 and older to records of the U.S. censuses of 1880 and 1900, conducted when these individuals were children. This group was a residual group from an earlier file that was reduced by the SSA after data checks that eliminated incorrect records. The results of the matched records for the residual file indicate that over 90% of the whites were accurately reported as supercentenarians, but only half of the blacks appeared to have attained age 110. The verification of age shows that the United States has more "true" supercentenarians than do other nations.     

Divergence in Age Patterns of Mortality Change Drives International Divergence in Lifespan Inequality

In the past six decades, lifespan inequality has varied greatly within and among countries even while life expectancy has continued to increase. How and why does mortality change generate this diversity? We derive a precise link between changes in age-specific mortality and lifespan inequality, measured as the variance of age at death. Key to this relationship is a young–old threshold age, below and above which mortality decline respectively decreases and increases lifespan inequality. First, we show for Sweden that shifts in the threshold’s location have modified the correlation between changes in life expectancy and lifespan inequality over the last two centuries. Second, we analyze the post–World War II (WWII) trajectories of lifespan inequality in a set of developed countries—Japan, Canada, and the United States—where thresholds centered on retirement age. Our method reveals how divergence in the age pattern of mortality change drives international divergence in lifespan inequality. Most strikingly, early in the 1980s, mortality increases in young U.S. males led to a continuation of high lifespan inequality in the United States; in Canada, however, the decline of inequality continued. In general, our wider international comparisons show that mortality change varied most at young working ages after WWII, particularly for males. We conclude that if mortality continues to stagnate at young ages yet declines steadily at old ages, increases in lifespan inequality will become a common feature of future demographic change.     

Towards a Theory of Medium Term Life Satisfaction: Similar Results for Australia,Britain and Germany

We analyse the Life Satisfaction trajectories of respondents in three long-running, national panel surveys: the Household, Income and Labour Dynamics Australia Survey (HILDA), the British Household Panel Survey (BHPS) and the German Socio-Economic Panel (SOEP). Previous research has shown that substantial minorities of respondents in all three countries recorded long term changes in LS (Fujita and Diener in J Personal Soc Psychol 88:158–64, 2005; Headey in Soc Indic Res 76:312–317, 2006; Headey et al. in Proc Natl Acad Sci 107:17922–7926, 2010; Headey et al. Soc Indic Res 112:725–48, 2013). In a recent SIR paper based on the German data (Headey and Muffels in Soc Indic Res, 2015. doi: 10.1007/s11205-015-1146-8), we showed graphs of LS trajectories which suggested—and subsequent statistical analysis confirmed—that respondents typically spend multiple consecutive years above and, in other periods, below their own long term mean level of LS. Here we extend the analysis to Australia and Britain, showing that results replicate in two more Western countries. It appears that most people go through relatively happy periods of life, and relatively unhappy periods. The evidence runs counter to set-point theory which views adult LS as stable, except for short term fluctuations due to life events. In the second half of the paper we try to contribute to a theory of medium term life satisfaction. We estimate structural equation models with two-way causation between LS and variables usually treated as causes of LS, including health, social support, frequency of social activities, and satisfaction with one’s work, partner and family life. In all three countries we find that there are positive feedback loops between these variables and LS, which partly account for extended periods of high or low LS. The two-way causation models are based on a modified concept of ‘Granger-causation’ (Granger in Econometrica 37(3):424–38, 1969). The main intuition behind Granger-causation is that if x can be shown to be statistically significantly related to y in a model which includes multiple lags of y, then it can be inferred that x is one cause of y.     

An Exploratory Study on the Quality of Life of older Chinese People Living alone in Hong Kong

This study successfully interviewed 109 randomly selected Chinese people aged 60 and over living alone in two public housing estates in an urban area of Hong Kong. The results show that mental health status, number of days staying in hospital, life satisfaction, age, and self-esteem are significant factors in predicting the life quality of older Chinese respondents living alone. The explanatory power of this model is 56.4. The results of this study are consistent with previous findings reported in the west and in Hong Kong. A subgroup analysis of those older Chinese respondents living alone who have offspring also living in Hong Kong shows that belief in childrens support in old age, good walking ability, and better self-reported health status via life satisfaction as the mediating variable, better self-reported health status and satisfactory self-reported financial status via self-esteem as the mediating variable, are crucial predictors of quality of life. This model explains 64.2% of the variance in quality of life from a subset of the predictor variables.     

农村第一代已婚独生子女父母养老心态及其影响因素分析

基于2011年江苏、四川两省720户中老年农民调查数据,以同龄的非独生子女父母为参照,对农村第一代已婚独生子女父母的养老心态及其影响因素进行探索性分析。结果表明,在对待自己养老问题的担心上,独生子女父母的担心程度略高于非独生子女父母。而在子女能否赡养、经济上能否支持、生病时能否照顾上,独生子女父母的担心程度均低于非独生子女父母,在年老时是否感到孤独寂寞上,独生子女父母担心程度略高于非独生子女父母。对独生子女父母养老总体心态的多因素方差分析发现,婚姻状况、亲子关系、子女婚后支持变化、居住条件及生活满意度等变量可能是显著影响研究对象养老心态的重要因素。     

Decompression of Period Old-Age Mortality: When Adjusted for Bias,the Variance in the Ages at Death Shows Compression

Formal derivations and empirical evidence, in the framework of Fries-Kannisto's hypothesis, show that the indicators of mortality compression based on age-at-death distribution, left-censored at a fixed old age, may be subject to a bias toward showing mortality decompression in the case of a mortality decline. The previously reported increasing variance in ages at death above fixed old ages in developed countries was mainly the effect of a mortality shift, not decompression. When adjusted for this bias, the indicators of variance in ages at death show a compression of period mortality.     

Stress Coping Strategies,Perceived Organizational Support and Marital Status as Predictors of Work–Life Balance among Nigerian Bank Employees

The study examined stress coping strategies, perceived organizational support and marital status as predictors of work–life balance. Two hundred and fifty-four bank workers participated in the study. Results of the regression analyses showed that stress coping strategies was a significant predictor of work–life balance (β = .34, p = .000) and contributed 11 % variance in work–life balance after controlling for the effects of gender, age and education. The result further revealed that perceived organizational support significantly predicted workers’ work–life balance (β = .22, p = .001) and contributed additional 4 % variance in work–life balance after the effects of gender, age, education and coping strategies have been controlled. Marital status was not related to work–life balance. The findings of the study were discussed based on Nigerian socio-economic realities. The implications of the findings to work–life policies and practices were discussed.     

The Set-Point Theory of Well-Being: Negative Results and Consequent Revisions

An adequate theory of happiness or subjective well-being (SWB) needs to link at least three sets of variables: stable person characteristics (including personality traits), life events and measures of well-being (life satisfaction, positive affects) and ill-being (anxiety, depression, negative affects). It also needs to be based on long-term data in order to account for long-term change in SWB. By including personality measures in the 2005 survey, the German Socio-Economic Panel (SOEP) became the first available dataset to provide long-term evidence about personality and change in one key measure of SWB, namely life satisfaction. Using these data, the paper suggests major revisions to the set-point theory of SWB; revisions which seek to account for long-term change. Previously, theory focused on evidence that individuals have their own set-point of SWB and revert to that set-point once the psychological impact of major life events has dissipated. But the new SOEP panel data show that significant minorities record substantial and apparently permanent upward or downward changes in life satisfaction. The paper aims to explain why most people’s SWB levels do not change, but why a minority do. The main new result, which must be regarded as tentative until replicated, is that the people most likely to record large changes in life satisfaction are those who score high on the personality traits of extraversion (E) and/or neuroticism (N). These people in a sense ‘roll the dice’ more often than others and so have a higher than average probability of recording long-term changes. Data come from the 3130 SOEP respondents who rated their life satisfaction every year from 1985 onwards, among whom 2843 also completed a set of questions about their personality in 2005.

中国高龄老人生活自理能力纵向动态研究

利用"中国老年健康长寿跟踪调查"1998年、2000年、2002年的跟踪数据分析中国高龄老人ADL的变动趋势及其影响因素。个体增长模型结果显示,高龄老人ADL状况随年龄增长出现了明显的下降趋势,ADL个体差异十分显著。个体之间的差异解释了ADL总差异的31.13%。经历三次追踪调查的高龄老人ADL均值较高,状况较好,下降速度较慢;基期具有3-4项残障的高龄老人,未来ADL下降最为迅速;基期ADL水平高的高龄老人,ADL下降较慢。从ADL的个体影响因素来看,对于基期ADL水平影响最大的变量是"年龄"、"疾病状况"以及"居住安排"等,而对观测期ADL变动速度影响最大的变量是"年龄"以及"过去是否经常从事体力劳动"等。     

Health and Other Aspects of the Quality of Life of Older People

Celebrating the United Nations' International Year of Older Persons, in September 1999 a survey research project was undertaken throughout the Northern Interior Health Region (NIHR) of British Columbia. A total of 875 people completed 23-page questionnaires, the average age of the respondents was 69 and the range ran from 55 to 95 years. Responses to the SF-36 questionnaire indicated that for male respondents aged 55–64, the mean score for the 8 dimensions was 74.4. This mean was practically identical to that of the United States norm for such people (74.5) and lower than that for the United Kingdom (77.4). For male respondents aged 65 and older, the mean was 68.3. This was numerically higher but again practically the same as that of the norm for the United States (68.1). For females aged 55–64, the mean score for 8 dimensions was 73. This was superior to that of the United States norm of (70.6) for such people and lower than that for the United Kingdom (74.6). For female respondents aged 65 and older, the mean score was 65.4. This was practically identical to that of the United States (65.5).Comparing 18 average figures for our respondents on satisfaction with specific domains of life (e.g., financial security, health, friendships) and life as a whole with those of average adults in Prince George in November 1999, we found that in all but two cases the older people's scores were higher. Only in the cases of satisfaction with health and overall happiness were older people's scores lower, and the differences were not statistically significant.Eleven percent of our respondents reported that they had been a victim of a crime in the last year, compared to 38% in our 1997 adult victimization survey. Older people had a more benign view than ordinary adults of the growth of crime in their neighbourhood and city, although exactly 64% of both groups thought that crime had increased in Canada. Although older people had a more optimistic view than other adults of the increase in crime in their neighbourhoods, fewer of the former than the latter felt safe out at night. Nevertheless, compared to adults surveyed in 1997, the behaviour of respondents in our survey of older people was not as constrained by concerns of criminal victimization.Two or three of the 8 SF-36 health dimensions explained 37% of the variation in life satisfaction scores, 34% of variation in happiness scores, 34% in satisfaction with the overall quality of life scores and 22% in satisfaction with one's overall standard of living. In every case, Mental Health was the dimension that had the greatest impact on our four dependent variables.When all of our potential predictors were entered into a regression equation simultaneously, we found that they could explain 60% of the variance in life satisfaction scores, 44% in happiness scores, 58% in satisfaction with the overall quality of life scores and 59% in satisfaction with one's overall standard of living scores.     

Stability and Change of Well Being: An Experimentally Enhanced Latent State-Trait-Error Analysis

This study uses longitudinal panel data and short-term retest data from the same respondents in the German Socio-economic Panel to estimate the contribution of state and trait variance to the reliable variance in judgments of life satisfaction and domain satisfaction. The key finding is that state and trait variance contribute approximately equally to the reliable variance in well being measures. Most of the occasion specific variance is random measurement error, although occasion-specific variation in state variance makes a reliable contribution for some measures. Moreover, the study shows high similarity in life satisfaction and average domain satisfaction for the stable trait component (r = .97), indicating that these two measures are influenced by the same stable dispositions. In contrast, state variance of the two measures is distinct, although still highly correlated (r = .77). Error variances of the two measures are only weakly correlated, indicating that most of the error component is indeed due to random measurement error.     

Estimates of mortality from infant mortality rates

Estimates of mortality rates and expectation of life at birth, using infant mortality rates, are examined on the basis of 150 life tables for both sexes. Least squares linear estimates are given as well as estimates of their variances. Model life table calculations, as proposed by the U.N. Population Branch, are then compared with these unbiased minimum variance estimates and shown to overestimate the expectation of life by more than two years on the average, and to be at most 68% efficient. Though better estimates are provided in this paper, their variance is still so large as to cast doubt on the practical usefulness of anv estimates based exclusively on infant mortality rates.     

The Happiness Workout

This study tests for causality from exercise and physical activity to life satisfaction (LS) by applying an instrumental variable approach with the respondents’ perceived benefits of exercise participation as instruments. Using data across 25 countries from the Eurobarometer survey, our results confirm the positive association between exercise and LS. In terms of causality, the results indicate that being active increases LS for both gender, though more for men than women. One main reason for this relationship is that exercise is perceived as being pleasurable, something that policy-makers should keep in mind when designing programmes to get us off the sofa.     

A higher-Order Gratitude Uniquely Predicts Subjective Well-Being: Incremental Validity Above the Personality and a Single Gratitude

This main purpose of this study tests whether a higher-order gratitude compassing multi-components (e.g., thank others, thank God, cherish blessings, appreciate hardship, and cherish the moment) explains variances in subjective well-being including life satisfaction and positive affect after controlling for gender, age, religion, the Big Five personality traits (e.g., openness, conscientiousness, extraversion, agreeableness, and neuroticism), and a single gratitude. A total of 504 undergraduate participants were recruited to completed five inventories measuring the variables of interest. The higher-order gratitude made a significant unique contribution to life satisfaction (10 % of the variance, p < .001) and positive affect (2 % of the variance, p < .001) beyond the effects of demographic variables, the Big Five personality traits, and a single gratitude. This is consistent with the theoretical stance that the higher-order gratitude is more than just the Big Five personality traits or a single gratitude and is important in its own right for subjective well-being. Furthermore, it implies a multi-components gratitude is in deed different from a unifactorial gratitude and it seems more reasonable that trait gratitude is a higher-order construct including lower-order components.
