The Grant Study is an 85-year continuing longitudinal study from the Study of Adult Development at Harvard Medical School, started in 1938. [2] It has followed 268 Harvard-educated men, the majority of whom were members of the undergraduate classes of 1942, 1943 and 1944. It has run in tandem with a study called "The Glueck Study," which included a second cohort of 456 disadvantaged, non-delinquent inner-city youths who grew up in Boston neighborhoods between 1940 and 1945. The subjects were all white males and of American nationality. As of 2024, the men continue to be studied. [3] They were evaluated at least every two years by questionnaires through information from their physicians and by personal interviews. Information was gathered about their mental and physical health, career enjoyment, retirement experience and marital quality. The goal of the study was to identify predictors of healthy aging.

Contents

The study, its methodology, and results are described in three books by a principal investigator in the study, George Vaillant. The first book, Adaptation to Life, describes the study up to a time when the men were 47 years of age. [4] The second book, Aging Well, describes a time when the inner-city men were 70 years old and those of the Harvard group were 80. [5] In 2012, Vaillant and Harvard University Press published the third book, Triumphs of Experience, which shared more findings from the Grant Study. [6]

The study is part of The Study of Adult Development, which is now under the direction of Dr. Robert J. Waldinger [7] [8] at Massachusetts General Hospital.

The study is unique partly because of the long time span of the cohort, and also partly because of the high social status of some of the study participants. Among the most notable Grant Study participants included Ben Bradlee, an editor of The Washington Post , and US President John F. Kennedy. [9]

Main results

George Vaillant, who directed the study for more than three decades, has published a summation of the key insights the study has yielded in the book Triumphs of Experience: The Men of the Harvard Grant Study: [6]

According to The Atlantic , George Vaillant's main conclusion is that the warmth of relationships throughout life has the greatest positive impact on life satisfaction. Put differently, Vaillant says the study shows: "Happiness is love. Full stop." [11]

Swinging, sometimes called wife-swapping, husband-swapping, or partner-swapping, is a sexual activity in which both singles and partners in a committed relationship sexually engage with others for recreational purposes. Swinging is a form of non-monogamy and is an open relationship. People may choose a swinging lifestyle for a variety of reasons. Practitioners cite an increased quality and quantity of sex. Some people may engage in swinging to add variety into their otherwise conventional sex lives or due to their curiosity. Some couples see swinging as a healthy outlet and means to strengthen their relationship.

<span class="mw-page-title-main">Happiness</span> Mental state, noted for pleasant emotions

Happiness is a positive and pleasant emotion, ranging from contentment to intense joy. Moments of happiness may be triggered by positive life experiences or thoughts, but sometimes it may arise from no obvious cause. The level of happiness for longer periods of time is more strongly correlated with levels of life satisfaction, subjective well-being, flourishing and eudaimonia. In common usage, the word happy can be an appraisal of those measures themselves or as a shorthand for a "source" of happiness. As with any emotion, the precise definition of happiness has been a perennial debate in philosophy.

Birth order refers to the order a child is born in their family; first-born and second-born are examples. Birth order is often believed to have a profound and lasting effect on psychological development. This assertion has been repeatedly challenged. Recent research has consistently found that earlier born children score slightly higher on average on measures of intelligence, but has found zero, or almost zero, robust effect of birth order on personality. Nevertheless, the notion that birth-order significantly influences personality continues to have a strong presence in pop psychology and popular culture.

The economics of happiness or happiness economics is the theoretical, qualitative and quantitative study of happiness and quality of life, including positive and negative affects, well-being, life satisfaction and related concepts – typically tying economics more closely than usual with other social sciences, like sociology and psychology, as well as physical health. It typically treats subjective happiness-related measures, as well as more objective quality of life indices, rather than wealth, income or profit, as something to be maximized.

<i>The Natural History of Alcoholism Revisited</i> Book by George Eman Vaillant

The Natural History of Alcoholism Revisited (1995) is a book by psychiatrist George E. Vaillant that describes two multi-decade studies of the lives of 600 American males, non-alcoholics at the outset, focusing on their lifelong drinking behaviours. By following the men from youth to old age it was possible to chart their drinking patterns and what factors may have contributed to alcoholism. Another study followed 100 severe alcoholics from a clinic eight years after their detoxification. The National Review hailed the first edition (1983) as "a genuine revolution in the field of alcoholism research" and said that "Vaillant has combined clinical experience with an unprecedented amount of empirical data to produce what may ultimately come to be viewed as the single most important contribution to the literature of alcoholism since the first edition of AA's Big Book." Some of the main conclusions of Vaillant's book are:

"Leisure refers to activities that a person voluntarily engages in when they are free from any work, social or familial responsibilities." Leisure satisfaction is the positive perceptions or feelings that an individual forms, elicits and gains as a result of engaging in leisure activities and choices. What can contribute to leisure satisfaction is to what degree an individual is currently satisfied with their leisure experiences and activities. An individual might attain positive feelings of contentment and happiness that result from the satisfaction of needs. Participation in leisure activities and leisure satisfaction are inextricably linked to an individual's health. Caldwell suspects that leisure activities may be associated with a number of defensive traits that enhance a person's resiliency to negative life experiences. Some aspects of leisure activities that can act as protective factors include: "[the activity] being personally meaningful, intrinsically interesting and/or challenging; offering social support and friendships; contributing to a sense of competence and/or self efficacy; offering a sense of personal control, choice and self-determination; and being relaxing and/or distracting the individual from negative life events." Leisure activities, although ranging in types, have also proven to be beneficial to health cross-culturally.

Sexual desire discrepancy (SDD) is the difference between one's desired frequency of sexual intercourse and the actual frequency of sexual intercourse within a relationship. Among couples seeking sex therapy, problems of sexual desire are the most commonly reported dysfunctions, yet have historically been the most difficult to treat successfully. Sexual satisfaction in a relationship has a direct relationship with overall relationship satisfaction and relationship well-being. Sexual desire and sexual frequency do not stem from the same domains, sexual desire characterizes an underlying aspect of sexual motivation and is associated with romantic feelings while actual sexual activity and intercourse is associated with the development and advancement of a given relationship. Thus together, sexual desire and sexual frequency can successfully predict the stability of a relationship. While higher individual sexual desire discrepancies among married individuals may undermine overall relationship well-being, higher SDD scores for females may be beneficial for romantic relationships, because those females have high levels of passionate love and attachment to their partner. Studies suggest that women with higher levels of desire relative to that of their partners' may experience fewer relationship adjustment problems than women with lower levels of desire relative to their partners'. Empirical evidence has shown that sexual desire is a factor that heavily influences couple satisfaction and relationship continuity which has been one of the main reasons for the interest in this research domain of human sexuality.

<span class="mw-page-title-main">Alcoholism in family systems</span> Social and psychological factors that cause alcoholism in families

Alcoholism in family systems refers to the conditions in families that enable alcoholism and the effects of alcoholic behavior by one or more family members on the rest of the family. Mental health professionals are increasingly considering alcoholism and addiction as diseases that flourish in and are enabled by family systems.

Cognitive epidemiology is a field of research that examines the associations between intelligence test scores and health, more specifically morbidity and mortality. Typically, test scores are obtained at an early age, and compared to later morbidity and mortality. In addition to exploring and establishing these associations, cognitive epidemiology seeks to understand causal relationships between intelligence and health outcomes. Researchers in the field argue that intelligence measured at an early age is an important predictor of later health and mortality differences.

Despite a large body of positive psychological research into the relationship between happiness and productivity, happiness at work has traditionally been seen as a potential by-product of positive outcomes at work, rather than a pathway to business success. Happiness in the workplace is usually dependent on the work environment. During the past two decades, maintaining a level of happiness at work has become more significant and relevant due to the intensification of work caused by economic uncertainty and increase in competition. Nowadays, happiness is viewed by a growing number of scholars and senior executives as one of the major sources of positive outcomes in the workplace. In fact, companies with higher than average employee happiness exhibit better financial performance and customer satisfaction. It is thus beneficial for companies to create and maintain positive work environments and leadership that will contribute to the happiness of their employees.

<span class="mw-page-title-main">Zest (positive psychology)</span> Zest for living

In positive psychology, zest is among the discrete strengths people possess. Having zest means treating life as an adventure and feeling motivated in challenging situations. People with zest display enthusiasm, excitement, and energy as they tackle life's tasks. Zest is a component of the virtue of courage in some positive psychology paradigms.

Life satisfaction is an evaluation of a person's quality of life. It is assessed in terms of mood, relationship satisfaction, achieved goals, self-concepts, and self-perceived ability to cope with their life. Life satisfaction involves a favorable attitude towards one's life—rather than an assessment of current feelings. Life satisfaction has been measured in relation to economic standing, degree of education, experiences, residence, and other factors.

Subjective well-being (SWB) is a self-reported measure of well-being, typically obtained by questionnaire.

<span class="mw-page-title-main">Maternal sensitivity</span>

Maternal sensitivity is a mother's ability to perceive and infer the meaning behind her infant's behavioural signals, and to respond to them promptly and appropriately. Maternal sensitivity affects child development at all stages through life, from infancy, all the way to adulthood. In general, more sensitive mothers have healthier, more socially and cognitively developed children than those who are not as sensitive. Also, maternal sensitivity has been found to affect the person psychologically even as an adult. Adults who experienced high maternal sensitivity during their childhood were found to be more secure than those who experienced less sensitive mothers. Once the adult becomes a parent themselves, their own understanding of maternal sensitivity will affect their own children's development. Some research suggests that adult mothers display more maternal sensitivity than adolescent mothers who may in turn have children with a lower IQ and reading level than children of adult mothers.

The six-factor model of psychological well-being is a theory developed by Carol Ryff that determines six factors that contribute to an individual's psychological well-being, contentment, and happiness. Psychological well-being consists of self-acceptance, positive relationships with others, autonomy, environmental mastery, a feeling of purpose and meaning in life, and personal growth and development. Psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events.

Robert J. Waldinger is an American psychiatrist, psychoanalyst, and Zen priest. He is a part-time professor of psychiatry at Harvard Medical School and directs the Harvard Study of Adult Development, one of the longest-running studies of adult life ever conducted.

Well-being is a multifaceted topic studied in psychology, especially positive psychology. Biologically, well-being is highly influenced by endogenous molecules that impact happiness and euphoria in organisms, often referred to as "well-being related markers". Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life.
