Abstract
Quality of life is one of the positive psychology concepts that gained popularity and acceptance in the second half of the twentieth century. Quality of life is a multifaceted concept that refers to the overall general happiness due to his subjective and objective evaluation of all aspects of his life. The quality of an individual’s life has multiple determinants, including values, goals, culture, and environment, in which the individual lives, desires, needs, and others. And the multiplicity of definitions of quality of life in the light of the theoretical approaches to its study led to the lack of agreement on a single definition of the concept of quality of life. An increasing number of studies have clarified the benefits of counseling interventions to improve the quality of life of members of society in all its groups, as well as the effectiveness of quality-of-life interventions in developing the positive traits of an individual’s personality. There is still an urgent need to study the impact of intervention strategies to improve the quality of life, especially for people with chronic diseases.
