[7] Research on positive psychology, well-being, eudaimonia and happiness, and the theories of Diener, Ryff, Keyes and Seligmann cover a broad range of levels and topics, including "the biological, personal, relational, institutional, cultural, and global dimensions of life.
[30] The remaining theoretical 20%, however, still leaves room for significant change in thoughts and behavior from environmental/learned sources that should not be understated, and the interpretation of variance in twin studies is controversial, even among clinical psychologists.
[47]: 250 Researchers focused their studies on PYD (positive youth development) and the eudaimonic identity theory in the context of three developmental elements: self-defining activities, personal expressiveness and goal-directed behaviours.
Psychological factors could include greater awareness of one's self and preferences; an ability to control desires and have more realistic expectations – unrealistic expectations tend to foster unhappiness; moving closer to death may motivate people to pursue personal goals; improved social skills, like forgiveness, may take years to develop – the practice of forgiveness seems linked to higher levels of happiness; or happier people may live longer and are slightly overrepresented in the elderly population.
[93] In addition, the good feelings associated with flourishing result in improvements to immune system functioning, cardiovascular recovery, lessened effects of negative affect, and frontal brain asymmetry.
[109][110] It is worth mentioning that a recent book, Anatomy of an Epidemic, challenges the use of non-conservative usage of medications for mental patients, specially with respect to their long-term positive feedback effects.
[113] In recent large panel studies divorce, death of a spouse, unemployment, disability and similar events have been shown to change the long-term subjective well-being, even though some adaptation does occur and inborn factors affect this.
[130] In 2005 a study conducted by Andrew Steptow and Michael Marmot at University College London, found that happiness is related to biological markers that play an important role in health.
"[134] Consistent results are that "apart from good health, happy people were more likely to be older, not smoke, have fewer educational qualifications, do strenuous exercise, live with a partner, do religious or group activities and sleep for eight hours a night.
The tendency to experience positive emotions was associated with greater resistance to colds and flu in interventional studies irrespective of other factors such as smoking, drinking, exercise, and sleep.
On the other hand, the balance of evidence indicates that homeopathy, aromatherapy, bowen therapy, Feldenkrais, herbalism, iridology, kinesiology, pilates, reflexology and rolfing shiatsu were classed as ineffective.
This evidence cannot be entirely explained by demographic or health variables including socio-economic status, exercise, smoking, and body mass index, suggesting a causal link.
"[171] In his book Stumbling on Happiness, psychologist Daniel Gilbert described research suggesting money makes a significant difference to the poor (where basic needs are not yet met), but has a greatly diminished effect once one reaches middle class (i.e. the Easterlin paradox).
Specifically, using subjective well-being data from China, the authors find that homeownership is associated with higher levels of life satisfaction, although this happiness premium is larger for people who have full ownership compared to those who have only a minor ownership stake in their home.”[188] According to the latest[174] systematic review of the economic literature on life satisfaction, living in rural areas seems to have some association with well-being, because the included studies tend to control for income and rural areas tend to be poor.
[197] Nevertheless, development of the skill lends to its application at certain times, which can be useful for the reasons just described; Professor of Psychology and Psychiatry Richard J. Davidson highly recommends "mindfulness meditation" for use in the accurate identification and management of emotions.
Genetic studies indicate genes for personality (specifically extroversion, neuroticism and conscientiousness), and a general factor linking all 5 traits, account for the heritability of subjective well-being.
The strengths that represent major strides in prevention include: courage, future mindedness, optimism, faith, work ethic, hope, honesty, perseverance, and the capacity for flow and insight.
In a research study by Pollmann-Schult (2014) on 13,093 Germans, it was found that when finances and time costs are held constant, parents are happier and show increased life satisfaction than non-parents.
A multiple regression showed that demandingness and responsiveness together explained as much as twenty-eight percent of the variance in eudaimonia, this suggests parenting played a major role in the development of this pursuit.
[276] Recently, Anderson et al. found that sociometric status (the amount of respect one has from face-to-face peer group) is significantly and causally related to happiness as measured by subjective well-being.
Clifton and Rath[284] discussed research conducted by Dr. Elizabeth Hurlock in 1925, where fourth, fifth and sixth graders were either praised, criticized or ignored, based on their work on math problems.
Therapists, counselors, coaches, various psychological professionals, HR departments, business strategists, and others, are using new methods and techniques to broaden and build upon the strengths of a wide population of individuals.
[297] Thomas and Tasker (2010) showed less worker autonomy, fewer opportunities for development, less-enriched work roles, and lower levels of supervisor support reflected the effect of industry growth on job satisfaction.
[301] Gardner's proposed alternatives loosely follow the pleasant/good/meaningful life classifications outlined above; he believes young people should be trained to pursue excellence in their field, as well as engagement (see flow, above) in accordance with their moral belief systems.
[243][244][312] Living in an environment with more green spaces is associated with higher well-being, partly due to the beneficial effects on psychological relaxation, stress alleviation, increased physical activity, and reduced exposure to air pollutants and noise, among others.
According to Diener and Suh, Collectivistic cultures are more likely to use norms and the social appraisals of others in evaluating their subjective well-being, whereas those [individualistic] societies are more likely to heavily weight the internal [frame of reference] arising from one's own happiness.
The study had three main findings: (1) People living in individualistic, rather than collectivist, societies are happier; (2) Psychological attributes referencing the individual are more relevant to Westerners; (3) Self-evaluating happiness levels depend on different cues, and experiences, from one's culture.
There are a number of mechanisms through which religion may make a person happier, including social contact and support that result from religious pursuits, the mental activity that comes with optimism and volunteering, learned coping strategies that enhance one's ability to deal with stress, and psychological factors such as "reason for being."
[339] An analysis of over 200 social studies contends that "high religiousness predicts a lower risk of depression and drug abuse and fewer suicide attempts, and more reports of satisfaction with sex life and a sense of well-being.
Meta analysis has found that find studies purporting the beneficial results of religiosity often fail to fully represent data correctly due to a number of issues such as self-report bias, the use of inappropriate comparison groups, and the presence of criterion contamination.
