Psychological well-being and life satisfaction are important aspects of our life experiences. They reflect an overall assessment of our state of mental well-being, mental health and level of life satisfaction. However, psychological well-being and life satisfaction may vary depending on a person's age. In this article, we will review the results of research on psychological well-being and life satisfaction in different age groups. Psychological well-being in childhood: Research shows that children generally have high levels of psychological well-being, especially during preschool childhood. At this age, children have a high degree of emotional stability, positive attitude and satisfaction with their relationships with loved ones. They also exhibit a capacity for play and creativity, which contributes to their psychological development and well-being. Psychological well-being during adolescence: With the transition to adolescence, a number of psychological changes are observed, associated with physiological and emotional transformations. Adolescents face issues of self-identity, self-acceptance, and social adaptation. Research shows that levels of psychological well-being at this age may be lower than those of children and adults. However, with a supportive social environment and the development of social skills, adolescents can achieve high levels of psychological well-being and life satisfaction. Psychological well-being in adults: The level of psychological well-being and life satisfaction of adults can be associated with various factors, such as career achievements, income level, quality of close relationships, health and self-esteem. Research shows that adults often experience levels of psychological well-being and life satisfaction that peak in middle age and may decline slightly thereafter. Psychological Well-Being in Old Age: Older adults can also achieve high levels of psychological well-being and life satisfaction despite physical and social changes associated with age. Research shows that older adults who have good health, an active social life and support from loved ones have higher levels of psychological well-being and life satisfaction. Factors influencing psychological well-being and life satisfaction: Psychological well-being and life satisfaction in different age groups may be related with various factors. Some of these include the quality of close relationships, social support, educational level, physical and mental health, self-esteem and achievement in various areas of life. Research shows that psychological well-being and life satisfaction vary across different age groups. Children and adolescents have their own characteristics in psychological well-being related to development and adaptation to the environment. Adults and older adults face other challenges related to work, relationships, and physical health. It is important to take these features into account when developing programs and policies aimed at supporting and increasing psychological well-being in different age groups.
