Purpose: "Psychosocial health" is a new term to comprehend the already established factors involved in mental health and psychological well-being. The term has not been specifically defined and explained within the framework of psychology. Design/methodology/approach: The study proposed and validated a new model of psychosocial health. Principal component analysis, exploratory factor analysis and confirmatory factor analysis were conducted by involving a total of 4,086 participants. Findings: Psychosocial health was interpreted as the "sexual, emotional, social, environmental, cognitive, religious, moral and spiritual satisfaction" of a person. The proposed model of psychosocial health was statistically validated. The additional findings revealed significantly higher levels of psychosocial health in women and significant inverse correlations between psychosocial health and age. Originality/value: The current paper provided a comprehensive picture of psychosocial health from a psychological perspective and presented a statistically reliable tool for measuring psychosocial health.
