This study aims to investigate the psychometric properties of the attachment scale in early childhood by examining its validity and reliability. The scale addresses attachment styles such as secure, anxious, avoidant and disorganised attachment, as well as dimensions such as emotional closeness, trust, independence and social interaction. It assesses how these dimensions influence the child's psychological and social development. The sample consisted of 30 children aged 3-5 years from four nurseries in different regions. The researcher used a descriptive statistical approach with various methods to measure validity, including expert validity and internal consistency, to ensure the accuracy of the assessments. Cronbach's alpha coefficient was used to assess reliability, and the results indicate a high level of reliability and consistency for the scale. The results showed that the scale has a high level of validity and reliability, making it a valuable tool for researchers and professionals studying attachment in early childhood.
