Adolescence is the age when an individual becomes integrated into the society of adults and a major transition starts taking place physically as well as psychologically. Therefore this stage is very sensitive and an important phase of life which shapes the entire future and it also predicts the quality of life an adolescent will lead. Attachment has become an important issue in clinical evaluation of, and legal decisions about, school-aged children. Bowlby's general framework of attachment formation in parent-child bonding posits that caregivers have predictable, common styles that impact a child's emotion regulation, social relatedness, capacity for self-reflection, and overall neurological development- factors that may extend through adulthood. So the aim of the study is to find out the association between the variables and how much it affects an adolescent behaviour and mental health. The sample consisted of 120 adolescent boys and girls' age ranging from 13-14 years and randomization technique was used to select them. Results were finally analyzed using product moment correlation. © Journal of the Indian Academy of Applied Psychology.
