Perceived meaning of life and satisfaction with life: A research synthesis using an online finding archive.

Introduction: "Meaning" and "happiness" are leading topics in positive psychology, but their relationship is not well understood. The first step to better understanding is to inspect the pattern of correlations found in the research literature. Specifically, we seek answers to the following questions of fact: (1) Is there a correlation between perceived meaning of life and satisfaction with life? (2) If so, is that correlation positive or negative? (3) How strong is this correlation? (4) How variable is this correlation across persons and situations? (5) Do the correlations differ across components of happiness? (6) What aspects of meaning are most/least associated with happiness? (7) What sources of meaning are most/least associated with happiness? (8) Does seeing meaning relate differently to happiness than searching for meaning? Method: We took stock of the available research findings, using the World Database of Happiness, which holds standardized descriptions of 171 observed relations between perceived meaning of life and satisfaction with life. Results: We found strong correlations between happiness and the degree of perceived meaning in life but little correlation with the pursuit of meaning. While the correlation with the degree of meaning is positive at the micro-level of individuals, it appears to be negative at the macro-level of nations. Discussion: Having established the above mentioned matters of fact, we considered the following questions on causality: (1) Is there an innate need for meaning? (2) How does the perceived meaning of life otherwise affect satisfaction with life? (3) How does satisfaction with life affect the perceived the meaning of life? (4) Why is the correlation positive at the micro-level of individuals, but negative at the macro-level of nations? Conclusions: We conclude that there is no innate human need for meaning. Still, the perceived meaning of life can affect life satisfaction in various other ways, while life satisfaction will also affect the sense of meaning. Both positive and negative effects can be involved, the balance of which tends to be positive for seeing meaning but close to neutral for pursuing meaning.

Why Studies in the Effect of Positive Psychological Interventions Should Use Life-Satisfaction as an Outcome.

The effect of positive psychological interventions (PPIs) is mostly assessed using self-report measures of positive mental health. These measures are problematic because (1) the content addressed is often not clear, (2) different scales are used to assess different notions of positive mental health, which impedes comparability, (3) the concept of positive mental health involves objective capabilities which are not well measurable using subjective self-estimates, and (4) the concept behind the measures denotes presumed chances for adaptation to life rather than adaptation as such. Therefore, we should also measure the effect of PPIs using life-satisfaction, which is (a) a clear-cut concept and as such tells us what an intervention brings about, (b) is well measurable using self-reports, since it is a subjective concept, (c) it allows better comparability across studies, and (d) it indicates actual adaptation to life instead of strengthening of presumed of chances for adaptation.

Will Happiness-Trainings Make Us Happier? A Research Synthesis Using an Online Findings-Archive.

Most people want to be happy and many look out for opportunities to achieve a more satisfying life. Following a happiness training is an option, but the effectiveness of such training is being questioned. In this research synthesis we assessed: (1) whether happiness training techniques add to the happiness of their users, (2) how much happiness training techniques add to happiness, (3) how long the effect of happiness training lasts, (4) what kinds of training techniques work best, and (5) what types of groups of people profit from taking happiness training. We took stock of the available research and found 61 reports of effect studies on training techniques, which together yielded 179 findings. These findings are available in an online "findings archive," the World Database of Happiness. Using links to this source allows us to condense information in tabular overviews, while providing the reader with access to much detail. Happiness training techniques seem to do what they are designed to do: 96% of the studies showed a gain in happiness post intervention and at follow-up, about half of the positive results were statistically significant. Studies with cross-sectional designs and studies that used control groups showed more mixed results. The average effect of happiness training was approximately 5% of the scale range. We conclude that taking a form of happiness training is advisable for individuals looking for a more satisfying life. Since happier workers tend to be more productive, organizations would be wise to provide such training techniques for their workforce.

What is animal happiness?

Today, we see a growing concern for the quality of life of nonhuman animals and an accompanying call for viable means of assessing how well animals thrive. Past research focused on minimizing negatives such as stress, while more recent endeavors strive to promote positives such as happiness. But what is animal happiness? Although often mentioned, the term lacks a clear definition. With recent advances in the study of animal emotion, current interest into positive rather than negative experiences, and the call for captive and domesticated animals to have good lives, the time is ripe to examine the concept of animal happiness. We draw from the human and animal literature to delineate a concept of animal happiness and propose how to assess it. We argue that animal happiness depends on how an individual feels generally-that is, a typical level of affect.

Co-development of Happiness Research: Addition to "Fifty Years After the Social Indicator Movement".

Social Indicators Research covers many topics, which each have their own history. Happiness research is one of these included topics. Longstanding interest in happiness revived since the 1960s together with the emergence of the social indicator movement. Happiness became a prominent issue in the movement and the movement has fostered the development of happiness research in several ways.

Contextual correlates of happiness in European adults.

OBJECTIVES: We aimed to examine the associations of both objectively assessed and perceived physical and social neighborhood characteristics with happiness in European adults. In addition, we aimed to study how these associations differed among subgroups. METHODS: Participants (N = 6037) of the cross-sectional SPOTLIGHT survey reported on their level of happiness using a 5-point Likert scale, and on perceived physical and social environmental neighborhood characteristics. Objective physical environmental characteristics were assessed using a Google Street View-based neighborhood audit. Associations of 14 physical and social environmental characteristics with happiness were analyzed using multivariable multinomial regression analyses with clustered standard errors. RESULTS: Living in neighborhoods with higher levels of aesthetics and more water and green space was associated with being very happy. Individuals who perceived their neighborhood to be safer, more functional and more aesthetic were more likely to be very happy. The associations of functionality and aesthetics with happiness were strongest in the Ghent region (Belgium), the Randstad (the Netherlands) and Greater London (United Kingdom). Perceived absence of air pollution was only associated with higher levels of happiness in more highly educated participants. Individuals with a larger social network, more social cohesion and who trusted their neighbors were more likely to be very happy. The association between social networks and happiness was somewhat stronger in men than in women. In general, the associations between environmental characteristics and happiness had similar directions and sizes across socio-economic and socio-demographic subgroups. CONCLUSIONS: This European study provided evidence that both objectively assessed and perceived physical and social characteristics of the neighborhood environment are associated with the happiness of its residents.

The '10 Excess' Phenomenon in Responses to Survey Questions on Happiness.

Happiness in nations is typically measured in surveys using a single question. A common question is: 'all things considered, how satisfied or dissatisfied are you with your life as-a-whole these days on a scale from 0 to 10?'. The responses typically follow a uni-modal distribution with highest frequencies between 5 and 8. Yet in some nations, the percentage of 10 responses stands out and is higher than the percentage of 9 responses. This is particularly present in Latin America and in the Middle East. In this paper we explore the prevalence of the '10-excess' pattern and check some possible explanations. We conclude that the 10-excess phenomenon is partly due to cultural influence.

Greater Happiness for a Greater Number: Did the Promise of Enlightenment Come True?

In the eighteenth century 'Enlightened' thinkers challenged the belief that happiness exists only in Heaven. They claimed that happiness is possible in earthly life and foresaw that greater happiness would be achieved using reason. Did this promise of greater happiness come true? Several scholars doubt that we have become any happier and some claim that happiness has declined. These critical claims are tested using the time trend data available in the World Database of Happiness, which cover the period 1950-2010 and involve 1531 data points in 67 nations yielding 199 time-series ranging for 10 to more than 40 years. The analysis reveals that happiness has risen in most nations. The average yearly rise in the 67 nations was +0.012 on scale 0-10, which equals a rise of one full point every 83 years. At this rate happiness must have improved by more than two points over the past two centuries and, together with increasing longevity, this denotes an unprecedented rise in happy life years.

Happy Protest Voters: The Case of Rotterdam 1997-2009.

Protest parties are on the rise in several European countries. This development is commonly attributed to a growing dissatisfaction with life and associated with declining quality of life in modern society of the lowest social strata. This explanation is tested in a cross-sectional analysis of voting and life-satisfaction in 63 districts of the city of Rotterdam in the Netherlands, where the share of protest voters increased from 10 % in 1994 to 31 % in 2009. Contrary to this explanation protest voting appeared not to be the most frequent in the least happy districts of Rotterdam, but in the medium happy segment. Also divergent from this explanation was that average happiness in city districts is largely independent of local living conditions, but is rather a matter of personal vulnerability in terms of education, income and health. These results fit alternative explanations in terms of middle class status anxiety.

Pooling Time Series Based on Slightly Different Questions About the Same Topic Forty Years of Survey Research on Happiness and Life Satisfaction in The Netherlands.

Survey research on subjective wellbeing in The Netherlands started in the early 1970s. The time series happiness and life satisfaction that have emerged since then are unfortunately based on slightly different survey items of which one part uses verbal response scales and another part uses numerical response scales. The diversity of the survey items and a number of other measurement issues, such as the effects of changes in survey mode, hamper comparison over time and make it difficult to establish whether life became any better over the last forty years. These problems can be tackled using the recently developed Reference Distribution Method with which responses to equivalent but not identical survey questions can be pooled to obtain long, consistent time series. We applied the Reference Distribution method to pool time series of happiness and life satisfaction. We conclude that in the past 40 years the Dutch have become slightly happier and satisfied with their lives.

Conversion of Verbal Response Scales: Robustness Across Demographic Categories.

Happiness and life satisfaction have traditionally been measured using verbal response scales, however, these verbal scales have not kept up with the present trend to use numerical response scales. A switch from a verbal scale to a numerical scale, however, causes a severe problem for trend analyses, due to the incomparability of the old and new measurements. The Reference Distribution Method is a method that has been developed recently to deal with this comparison problem. In this method use is made of a reference distribution based on responses to a numerical scale which is used to decide at which point verbally labelled response options transit from one state to another, for example from 'happy' to 'very happy'. Next, for each wave of the time series in which the verbal scale is used, a population mean is estimated for the beta distribution that fits best to these transition points and the responses in this wave. These estimates are on a level that is comparable to that of the mean of the reference distribution and are appropriate for use in an extended time series based on the responses measured using a verbal and a numerical scale. In this paper we address the question of whether the transition points derived for the general population can be used for demographic categories to produce reliable, extended time series to monitor differences in trends among these categories. We conclude that this is possible and that it is not necessary to derive transition points for each demographic category separately.

Social conditions for human happiness: A review of research.

Empirical research on happiness took off in the 1970s and accelerated after the emergence of positive psychology by 2000. Today this has resulted in some 23,000 research findings. In this article, I take stock of the findings on social conditions for happiness and distinguish between conditions at the macro level of society, the meso level of organisations and the micro level of individual conditions. A new review technique is applied, an online findings archive is used, in which research findings on happiness are described in a uniform way and sorted by subject.

Mental health care and average happiness: strong effect in developed nations.

Mental disorder is a main cause of unhappiness in modern society and investment in mental health care is therefore likely to add to average happiness. This prediction was checked in a comparison of 143 nations around 2005. Absolute investment in mental health care was measured using the per capita number of psychiatrists and psychologists working in mental health care. Relative investment was measured using the share of mental health care in the total health budget. Average happiness in nations was measured with responses to survey questions about life-satisfaction. Average happiness appeared to be higher in countries that invest more in mental health care, both absolutely and relative to investment in somatic medicine. A data split by level of development shows that this difference exists only among developed nations. Among these nations the link between mental health care and happiness is quite strong, both in an absolute sense and compared to other known societal determinants of happiness. The correlation between happiness and share of mental health care in the total health budget is twice as strong as the correlation between happiness and size of the health budget. A causal effect is likely, but cannot be proved in this cross-sectional analysis.

Homogenizing Responses to Different Survey Questions on the Same Topic: Proposal of a Scale Homogenization Method Using a Reference Distribution.

Survey data are often used for comparison purposes, such as comparisons across nations or comparisons over time. To be effective, this would require equivalent questions and equivalent responses options to the questions. Yet there is a lot of variation in the response scales used, which, for example, differ in the number of response options used and the labeling of these options. This is the case in happiness research, and as a result most of the research data in this field is incomparable. Several methods have been proposed to transform ratings on verbal response scales to a common numerical scale, typically ranging from 0 to 10. In this paper we give an overview of the progress made in those Scale Homogenization methods over time. We describe two early methods: Linear Stretch and the Semantic Judgement of Fixed Word Value Method. Next we discuss the Semantic Judgement of Word Value in Context Method in more detail. Based on these discussions we propose a new Reference Distribution Method. We apply the Semantic Judgement of Word Value in Context and the Reference Distribution Methods to data on happiness in The Netherlands for the years 1989-2009. We show that the Reference Distribution Method produces comparable time series on different questions and that it allows discontinuities in data to be corrected.

Biological pathways and genetic mechanisms involved in social functioning.

PURPOSE: To describe the major findings in the literature regarding associations between biological and genetic factors and social functioning, paying special attention to: (1) heritability studies on social functioning and related concepts; (2) hypothesized biological pathways and genetic variants that could be involved in social functioning, and (3) the implications of these results for quality-of-life research. METHODS: A search of Web of Science and PubMed databases was conducted using combinations of the following keywords: genetics, twins, heritability, social functioning, social adjustment, social interaction, and social dysfunction. RESULTS: Variability in the definitions and measures of social functioning was extensive. Moderate to high heritability was reported for social functioning and related concepts, including prosocial behavior, loneliness, and extraversion. Disorders characterized by impairments in social functioning also show substantial heritability. Genetic variants hypothesized to be involved in social functioning are related to the network of brain structures and processes that are known to affect social cognition and behavior. CONCLUSIONS: Better knowledge and understanding about the impact of genetic factors on social functioning is needed to help us to attain a more comprehensive view of health-related quality-of-life (HRQOL) and will ultimately enhance our ability to identify those patients who are vulnerable to poor social functioning.

The medicine is worse than the disease: Comment on Delhey and Kohler's proposal to measure inequality in happiness using 'instrument-effect-corrected' standard deviations.

Inequality of happiness in nations can be measured using the standard deviation of responses to surveys questions. The standard-deviation is not quite independent of the mean, being zero when everybody is maximally happy or unhappy while the possible value of the standard deviation is highest when the mean is in the middle of the response scale. Delhey and Kohler see this intrinsic dependency as a problem and propose two ways to compute 'corrected' standard deviations. I advise against this medicine. One reason is that there is no real disease, since the presumed problem does not occur with commonly used numerical rating scales of 10 or more steps. The second reason is that one of Delhey and Kohler's medicines have side effects, their first correction affects the mean and their second correction is based on implausible assumptions. A third reason is that there are better ways to estimate the effect happiness-inequality net happiness-level. Partialling out mean happiness did not affect the non-correlation between inequality of income and inequality of happiness in an analysis of 116 nations.

Finding the key to happy aging: a day reconstruction study of happiness.

OBJECTIVES: The main aim of this study was to examine the roles of physical passivity and extraversion in the relationship between daily engagement in activities and daily happiness among older adults. METHOD: A day reconstruction method was used to accurately examine day-to-day activities and happiness. In total, 438 participants completed a monthly electronic diary survey over a 2-year period, generating 79,181 reported activities and momentary happiness scores. RESULTS: The results show that happiness increases when older adults combine effortful social, physical, cognitive, and household activities with restful activities. Furthermore, participation in social activities mediated the direct relationship between extraversion and happiness. Also, individuals who score high on extraversion derive greater happiness from social activities compared with their low-extravert counterparts. CONCLUSIONS: The study extends activity theory by demonstrating that combining effortful activities with restful activities leads to greater happiness among older adults. Also, personality traits such as extraversion play a decisive role in the kind of activities that contribute most to daily happiness.

Life is Getting Better: Societal Evolution and Fit with Human Nature.

Human society has changed much over the last centuries and this process of 'modernization' has profoundly affected the lives of individuals; currently we live quite different lives from those forefathers lived only five generations ago. There is difference of opinion as to whether we live better now than before and consequently there is also disagreement as to whether we should continue modernizing or rather try to slow the process down. Quality-of-life in a society can be measured by how long and happy its inhabitants live. Using these indicators I assess whether societal modernization has made life better or worse. Firstly I examine findings of present day survey research. I start with a cross-sectional analysis of 143 nations in the years 2000-2008 and find that people live longer and happier in today's most modern societies. Secondly I examine trends in modern nations over the last decade and find that happiness and longevity have increased in most cases. Thirdly I consider the long-term and review findings from historical anthropology, which show that we lived better in the early hunter-gatherer society than in the later agrarian society. Together these data suggest that societal evolution has worked out differently for the quality of human life, first negatively, in the change from a hunter-gatherer existence to agriculture, and next positively, in the more recent transformation from an agrarian to an industrial society. We live now longer and happier than ever before.
