Psychosocial health in early childhood plays a crucial role in long-term well-being, yet disparities persist due to socioeconomic and environmental factors, especial for children in the early life. This thesis investigates the relative factors associated with psychosocial health in young children, focusing on three key areas. Part I explores the influence of socioeconomic status and parental migration background on psychosocial health in two-year-olds and its development over time. Part II examines the impact of stressful life events on psychosocial and general health from ages two to four. Part III addresses parental help-seeking for psychosocial concerns and the factors related to parenting stress. By identifying early risk factors and the role of parental behaviors, this research provides insights for policymakers and healthcare professionals to support mental health interventions for young children and their families.
