Adolescence is a crucial developmental period characterized by significant physical, psychological, and emotional changes. Parental attachment and self-esteem are critical factors influencing adolescents' mental well-being. To assess parental attachment and self-esteem levels among adolescent girls and to examine their interrelationship. A descriptive correlational study was conducted among 100 adolescent girls aged 16 to 18 years at SFS PU College, Tamaka, Kolar. Data were collected using the Kenny’s Parental Attachment Questionnaire and the Rosenberg Self-Esteem Scale. Statistical analyses included descriptive statistics, Pearson’s correlation, and Chi-square tests to identify associations with demographic variables. The majority (80%) of participants exhibited moderate parental attachment, while 55% had high self-esteem. A positive correlation (r = 0.195, p < 0.05) was observed between parental attachment and self-esteem. Significant associations were found between self-esteem and demographic variables such as age and stream (p < 0.05). Strengthening parental bonds may positively impact adolescents' self-esteem and overall psychological well-being. Further intervention studies are recommended to explore effective strategies for fostering parental attachment.
