Hormone imbalances are becoming increasingly common due to changes in dieting pattern and significant environmental factors. One of them, now a days faced by adolescents (4-6%), is Polycystic Ovarian syndrome which is a common gynaecological endocrinopathy associated with problems like menstrual irregularities, hirsutism, obesity, insulin resistance, acne, and in later life it may lead to infertility, diabetes mellitus, and uterine cancer. Thus awareness is essential for early identification, management, and also to curtail the immediate and longterm complications of PCOS. The objective of the work is to find out the effectiveness of VATM in increasing awareness about PCOS among adolescents. Here one group pre & post test design with pre experimental study of 60 adolescents girls aged between 16-19 years were included. This study was conducted at Gayatri women's +2 science college, Berhampur, Ganjam, Odisha. The findings revealed that the overall mean knowledge score in pre-test was (13.96± 3.07), which is 41.05%, whereas in post-test it was (23.41± 4.0), which is 68.85% revealing good knowledge and the effectiveness was 27.8%. Hence video assisted teaching module is effective in enhancing knowledge among adolescents regarding PCOS. And also it can be recommended for the nurse midwives to counsel their clients who are at risk for developing PCOS regarding the risk factors, life style changes, and treatment options available with newer modalities, so that the future consequences of it can be well prevented.
