Previous international research and research in the Republic of Croatia has shown that psychosomatic symptoms in children are on the rise. The prevalence of symptoms in children is between 20% and 69%, and they can be reactions to stressful events, indicators of various psychological disorders, and one of the symptoms of acute diseases and chronic conditions. Psychosomatic symptoms affect the quality of life, personality characteristics, and specific life experiences. Objective: To examine the relationship between selfassessment of the quality of life and the frequency and intensity of psychosomatic symptoms of students in upper grades of primary school. Method: Upper elementary school students (N=207) anonymously selfassessed the occurrence of psychosomatic symptoms and the quality of their lives. Students self-assessed interference of the psychosomatic symptoms in daily activities from the list of 35 psychosomatic symptoms (vascular, respiratory, gastrointestinal, dermatological, psychoneurological, and other) and three supplementary health-related questions using the Psychosomatic Symptoms Questionnaire for Children and Adolescents. On the Personal Wellbeing Index Questionnaire, students self-assessed their satisfaction with the quality of their life in seven areas (material well-being, health, achievement, interpersonal relationships, security, connection and belonging to the community, and security in the future). Results: The results show that the quality of life is moderately related to the frequency and disturbances of psychosomatic symptoms and students’ general health. The students’ self-assessment of health proved to be a stronger predictor of quality of life in relation to the frequency of psychosomatic symptoms, regardless of the student’s gender. The difference in the frequency of psychosomatic symptoms is between 5th and 7th-grade students. Younger students report less psychosomatic symptoms.
