Abstract: The prevalence of depression and anxiety symptoms in children and adolescents has been increasing, influenced by multiple risk factors that negatively impact mental health and well-being. This study aimed to evaluate the psychometric properties of the Depression, Anxiety, and Stress Scale (DASS) in children aged 9 and older and to examine the relationship between its dimensions, well-being, and psychological symptoms in Portuguese children. The sample included 618 participants (50.2% male), aged 9 to 18 years (M = 12.2; SD = 2.88). Results showed that the Portuguese DASS has good psychometric properties, with a stable and comparable structure across gender and age groups. Well-being (WHO-5) was negatively associated with anxiety, depression, and stress, indicating that higher psychological distress corresponds to lower perceived well-being. This study validates the use of the DASS in younger populations, providing a reliable tool for research and clinical practice in Portugal. Early detection of symptoms is essential to prevent academic, social, and long-term mental health consequences.
