1. Introduction

Well-being has emerged as a pivotal concept in contemporary discourse, extending its influence across diverse fields, including psychology, public health, economics, and social policy. Once largely considered the purview of philosophy and religion, well-being has undergone a scientific transformation, with researchers actively exploring its nature, determinants, and consequences. This shift reflects a growing recognition that well-being is not merely the absence of illness but rather a positive state of flourishing that contributes to enhanced individual functioning, stronger social connections, and greater societal prosperity. This report aims to provide a comprehensive overview of well-being, examining its various facets, the factors that influence it, the methods used to measure it, and the interventions designed to enhance it.

The evolution of well-being research has been marked by several key milestones. The emergence of positive psychology, spearheaded by Seligman and Csikszentmihalyi (2000), provided a crucial impetus, shifting the focus from pathology and dysfunction to the study of human strengths and positive experiences. This movement challenged the traditional disease-oriented model and emphasized the importance of understanding and promoting factors that contribute to happiness, resilience, and overall life satisfaction. Concurrently, advancements in neuroscience and genetics have provided valuable insights into the biological underpinnings of well-being, revealing the complex interplay between genes, brain function, and subjective experience. Furthermore, the rise of behavioral economics and social epidemiology has highlighted the significance of social and environmental factors in shaping well-being outcomes.

Despite the increasing attention devoted to well-being, significant challenges remain. One persistent issue is the lack of a universally accepted definition of well-being, with various conceptualizations emphasizing different aspects of the construct. For example, some researchers focus on subjective well-being (SWB), which encompasses individuals’ cognitive and affective evaluations of their lives (Diener, 1984). Others emphasize psychological well-being (PWB), which focuses on aspects such as autonomy, purpose in life, and personal growth (Ryff, 1989). Still others prioritize social well-being, which includes aspects such as social integration, social acceptance, and social contribution (Keyes, 1998). The lack of a unified framework hinders communication and collaboration across disciplines and complicates the development of effective interventions. This report aims to clarify these differing perspectives and explore their interrelationships.

2. Defining and Conceptualizing Well-being

Defining well-being is a complex undertaking due to its multifaceted nature and subjective interpretations. While a universally accepted definition remains elusive, several prominent conceptualizations have emerged, each offering a unique perspective on the core components of well-being. These perspectives can be broadly categorized into hedonic, eudaimonic, and social well-being.

2.1 Hedonic Well-being

Hedonic well-being (HWB) centers on the experience of pleasure and the avoidance of pain. It is primarily concerned with maximizing positive affect (e.g., happiness, joy, contentment) and minimizing negative affect (e.g., sadness, anger, anxiety). Subjective well-being (SWB) is a dominant framework within the hedonic tradition, encompassing three primary components: life satisfaction (a cognitive evaluation of one’s life as a whole), positive affect, and negative affect (Diener, 1984). SWB emphasizes the individual’s subjective appraisal of their life circumstances and their emotional reactions to those circumstances. Critiques of the hedonic view often point to its potential for shallowness and its neglect of deeper meaning and purpose in life. Focusing solely on pleasure can lead to a superficial understanding of well-being and may not adequately capture the complexities of human flourishing. Furthermore, hedonic adaptation, the tendency to return to a baseline level of happiness despite positive or negative life events, can limit the long-term impact of purely pleasure-seeking activities.

2.2 Eudaimonic Well-being

Eudaimonic well-being (EWB) emphasizes meaning, purpose, and self-realization. It focuses on living in accordance with one’s values, developing one’s potential, and contributing to something larger than oneself. Ryff’s (1989) model of psychological well-being (PWB) is a prominent example of the eudaimonic approach. This model comprises six dimensions: autonomy (independence and self-determination), environmental mastery (the ability to manage one’s environment), personal growth (a sense of continued development), positive relations with others (satisfying and trusting relationships), purpose in life (a sense of meaning and direction), and self-acceptance (a positive attitude toward oneself). EWB emphasizes the importance of engaging in activities that are intrinsically meaningful and that promote personal growth, even if they are not always pleasurable. Critics of the eudaimonic view argue that it can be overly prescriptive, imposing specific values and ideals of what constitutes a good life. Furthermore, the emphasis on self-realization may neglect the importance of social context and the interconnectedness of individuals. The concept of striving for perfection may cause anxiety for some individuals if they feel unable to reach their perceived potential.

2.3 Social Well-being

Social well-being (SWB) focuses on an individual’s relationships with others and their sense of belonging to a community. Keyes’ (1998) model of social well-being includes five dimensions: social integration (the feeling of belonging to a community), social acceptance (a positive attitude toward others), social contribution (the belief that one is contributing to society), social coherence (the sense that society is understandable and predictable), and social actualization (the belief that society can improve). SWB highlights the importance of social connections, civic engagement, and a sense of shared identity. A strong sense of social well-being is associated with improved mental and physical health, increased resilience, and greater civic participation. However, the social well-being perspective can be criticized for its potential to prioritize conformity and social harmony over individual autonomy and critical thinking. Furthermore, the emphasis on belonging may overlook the experiences of marginalized groups and individuals who do not fit neatly into existing social structures.

2.4 Integrating Perspectives

While hedonic, eudaimonic, and social well-being are often presented as distinct constructs, there is growing recognition that they are interconnected and mutually reinforcing. A comprehensive understanding of well-being requires integrating these different perspectives. For example, engaging in meaningful activities can lead to both eudaimonic and hedonic well-being, as individuals experience a sense of purpose and accomplishment while also enjoying the process. Similarly, strong social connections can contribute to both social well-being and hedonic well-being, as individuals derive pleasure and support from their relationships. A synergistic approach that combines elements of all three perspectives provides a richer and more nuanced understanding of well-being. It allows for the recognition of both the subjective experience of happiness and the objective pursuit of meaning and purpose within a supportive social context.

3. Determinants of Well-being Across the Lifespan

Well-being is influenced by a complex interplay of factors spanning biological, psychological, social, and environmental domains. These determinants interact dynamically across the lifespan, shaping an individual’s overall sense of well-being. Understanding these factors is crucial for developing effective interventions to promote and enhance well-being at different stages of life.

3.1 Biological Factors

Genetic predispositions play a significant role in shaping an individual’s susceptibility to mental health conditions, temperament, and personality traits, all of which can influence well-being. Twin studies have consistently demonstrated the heritability of SWB, suggesting that genetic factors account for a substantial portion of the variance in happiness and life satisfaction (Lykken & Tellegen, 1996). Neurotransmitters, such as serotonin, dopamine, and norepinephrine, are crucial for regulating mood, motivation, and reward processing. Imbalances in these neurotransmitter systems have been implicated in depression, anxiety, and other mental health disorders that can negatively impact well-being. The hypothalamic-pituitary-adrenal (HPA) axis, the body’s primary stress response system, also plays a crucial role. Chronic stress and dysregulation of the HPA axis can lead to elevated cortisol levels, which can impair cognitive function, suppress the immune system, and increase the risk of mental health problems. Additionally, physical health conditions, such as chronic pain, cardiovascular disease, and neurological disorders, can significantly impact well-being by limiting physical functioning, causing discomfort, and affecting mental health. These biological factors can significantly impact the overall well-being of an individual.

3.2 Psychological Factors

Cognitive processes, such as optimism, self-esteem, and resilience, are crucial for shaping an individual’s perception of their life and their ability to cope with challenges. Optimistic individuals tend to interpret events in a positive light, which can buffer against stress and promote positive emotions. High self-esteem is associated with greater confidence, self-acceptance, and a sense of worthiness. Resilience, the ability to bounce back from adversity, is essential for maintaining well-being in the face of life’s inevitable setbacks. Emotional regulation skills, the ability to manage and express emotions effectively, are also critical. Individuals who can regulate their emotions are better able to cope with stress, maintain positive relationships, and avoid emotional outbursts. Personality traits, such as extraversion, conscientiousness, and agreeableness, are associated with higher levels of well-being. Extraverted individuals tend to be more sociable and outgoing, conscientious individuals are more organized and responsible, and agreeable individuals are more cooperative and compassionate. The absence of psychological disorders, such as depression, anxiety, and post-traumatic stress disorder (PTSD), is also essential for maintaining well-being. These conditions can significantly impair an individual’s ability to experience positive emotions, engage in meaningful activities, and maintain healthy relationships.

3.3 Social Factors

Social support, including close relationships with family, friends, and romantic partners, provides individuals with a sense of belonging, security, and emotional support. Social support can buffer against stress, promote positive emotions, and enhance overall well-being. Social inclusion, the feeling of being accepted and valued by a community, is also crucial. Socially excluded individuals are more likely to experience loneliness, isolation, and depression. Cultural norms and values can shape an individual’s understanding of well-being and their expectations for a good life. Cultures that emphasize individualism may prioritize personal achievement and self-expression, while cultures that emphasize collectivism may prioritize social harmony and group cohesion. Socioeconomic status (SES), including income, education, and occupation, is strongly associated with well-being. Individuals with higher SES tend to have better access to resources, opportunities, and healthcare, which can enhance their overall well-being. Exposure to discrimination and prejudice can negatively impact well-being by creating stress, undermining self-esteem, and limiting opportunities. These aspects of society have a significant impact on the perceived and true well-being of an individual.

3.4 Environmental Factors

Access to green spaces, such as parks, forests, and gardens, has been shown to promote well-being by reducing stress, improving mood, and encouraging physical activity. Exposure to pollution and noise can negatively impact well-being by causing stress, disrupting sleep, and increasing the risk of physical and mental health problems. Safety and security, including freedom from violence, crime, and natural disasters, are essential for creating a sense of stability and well-being. Access to resources and services, such as healthcare, education, and transportation, is crucial for meeting basic needs and promoting opportunities for growth and development. The built environment, including the design of buildings and cities, can also influence well-being by affecting social interaction, physical activity, and access to resources. Considering these enviornmental factors are vital when considering well-being.

4. Measuring Well-being

The measurement of well-being is a complex and multifaceted endeavor, reflecting the diverse conceptualizations of the construct. Researchers employ a range of methodologies, each with its strengths and limitations, to assess different aspects of well-being. These methods can be broadly categorized into self-report measures, experience sampling methods, and physiological measures.

4.1 Self-Report Measures

Self-report questionnaires are the most widely used method for assessing well-being. These questionnaires typically ask individuals to rate their feelings, thoughts, and experiences related to various aspects of well-being, such as life satisfaction, positive affect, negative affect, and purpose in life. The Satisfaction with Life Scale (SWLS) is a widely used measure of life satisfaction (Diener et al., 1985). It consists of five items that ask individuals to rate their overall satisfaction with their lives. The Positive and Negative Affect Schedule (PANAS) is a commonly used measure of positive and negative affect (Watson et al., 1988). It consists of two scales that assess the extent to which individuals have experienced various positive and negative emotions over a specific period. Ryff’s Scales of Psychological Well-being (SPWB) are a comprehensive measure of psychological well-being, assessing the six dimensions of autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance (Ryff, 1989). The advantage of self-report measures is their ease of administration and cost-effectiveness. They can be administered to large samples and provide valuable insights into individuals’ subjective experiences. However, self-report measures are susceptible to response biases, such as social desirability bias (the tendency to present oneself in a favorable light) and recall bias (the difficulty in accurately recalling past events and feelings). Participants may feel compelled to lie or embelish their responses.

4.2 Experience Sampling Methods

Experience sampling methods (ESM), also known as ecological momentary assessment (EMA), involve collecting data on individuals’ thoughts, feelings, and behaviors in real-time, in their natural environments (Csikszentmihalyi & Larson, 1987). Participants are typically signaled at random intervals throughout the day and asked to complete brief questionnaires or diaries. ESM allows researchers to capture the dynamic fluctuations in well-being over time and to examine the relationship between well-being and specific events or activities. ESM reduces recall bias and provides a more accurate assessment of individuals’ everyday experiences. The primary disadvantage of ESM is its intensive nature, which can be burdensome for participants. Furthermore, ESM data can be complex to analyze, requiring specialized statistical techniques. Furthermore, this method is limited because it is difficult to apply to people who lack smartphones or other devices used to transmit the data.

4.3 Physiological Measures

Physiological measures offer an objective assessment of well-being by examining biological markers associated with stress, emotion, and health. These measures include heart rate variability (HRV), cortisol levels, and immune function. HRV reflects the variability in the time interval between heartbeats, which is an indicator of autonomic nervous system activity. Higher HRV is generally associated with greater resilience and well-being (Thayer & Lane, 2000). Cortisol, a stress hormone, can be measured in saliva, blood, or urine. Elevated cortisol levels are indicative of chronic stress, which can negatively impact well-being. Immune function can be assessed by measuring levels of various immune cells and cytokines in blood samples. Impaired immune function is associated with increased susceptibility to illness and reduced well-being. Physiological measures provide objective data that are not susceptible to response biases. However, these measures are often expensive and require specialized equipment and expertise. Furthermore, the interpretation of physiological data can be complex, as many factors can influence these measures.

5. Interventions to Promote Well-being

Numerous interventions have been developed to promote and enhance well-being across the lifespan. These interventions range from individual-level therapies and lifestyle modifications to community-based programs and policy initiatives. Understanding the effectiveness of these interventions is crucial for developing evidence-based strategies to foster well-being and resilience.

5.1 Individual-Level Interventions

Cognitive-behavioral therapy (CBT) is a widely used therapy that focuses on identifying and changing negative thought patterns and behaviors. CBT has been shown to be effective in treating depression, anxiety, and other mental health conditions that can negatively impact well-being (Beck, 1976). Mindfulness-based interventions (MBIs) involve cultivating awareness of the present moment without judgment. MBIs have been shown to reduce stress, improve mood, and enhance overall well-being (Kabat-Zinn, 1990). Positive psychology interventions (PPIs) focus on enhancing positive emotions, strengths, and virtues. PPIs include activities such as gratitude exercises, acts of kindness, and identifying and using one’s signature strengths (Seligman et al., 2005). Lifestyle modifications, such as regular exercise, healthy diet, and adequate sleep, can also significantly impact well-being. Exercise has been shown to improve mood, reduce stress, and enhance cognitive function. A healthy diet provides the body with the nutrients it needs to function optimally, while adequate sleep is essential for restoring energy and regulating mood. These actions can increase and stabilize well-being.

5.2 Community-Based Interventions

Social support groups provide individuals with a sense of belonging, connection, and emotional support. These groups can be particularly beneficial for individuals experiencing loneliness, isolation, or chronic illness. Community gardens provide opportunities for individuals to connect with nature, engage in physical activity, and build social connections. Arts and cultural programs provide opportunities for individuals to express themselves creatively, connect with others, and experience beauty and inspiration. Workplace wellness programs aim to promote the health and well-being of employees by providing access to resources such as health screenings, fitness programs, and stress management workshops. If businesses are keen to grow and improve the well-being of their staff is a priority.

5.3 Policy Initiatives

Policies that promote access to healthcare, education, and employment can significantly impact well-being by reducing poverty, improving health outcomes, and increasing opportunities for growth and development. Policies that protect the environment, such as clean air and water regulations, can enhance well-being by reducing exposure to pollution and promoting access to green spaces. Policies that promote social inclusion and reduce discrimination can improve well-being by creating a more equitable and just society. Policies that support work-life balance, such as paid family leave and flexible work arrangements, can enhance well-being by reducing stress and promoting greater balance between work and personal life. The Government has a huge role to play in improving well-being across society.

6. Future Directions and Research Gaps

While significant progress has been made in understanding and promoting well-being, several key research gaps remain. Future research should focus on developing more comprehensive and integrated models of well-being that incorporate biological, psychological, social, and environmental factors. Longitudinal studies are needed to examine the long-term impact of various determinants and interventions on well-being across the lifespan. More research is needed to understand the cultural variations in well-being and to develop culturally appropriate interventions. The use of technology-based interventions, such as mobile apps and online platforms, offers promising avenues for delivering well-being interventions at scale. Further research is needed to evaluate the effectiveness of these interventions. Greater efforts are needed to translate research findings into practical applications and to promote the adoption of evidence-based well-being interventions in clinical practice, community settings, and policy initiatives. By addressing these research gaps and promoting the translation of research findings into practice, we can make significant strides in fostering well-being and resilience for individuals and communities.
