A study to assess the effectiveness of Video-Assisted Teaching on No-Scalpel Vasectomy among industrial workers in selected Industry Hyderabad, Andhra Pradesh. The research approach selected for the study was pre-experimental approach with one group pre and post-test design. The study was conducted among 30 industrial workers at Deepak Nitrate Industry Jeedimetla Hyderabad. Samples were selected for the study by using Convenience sampling technique. The data were collected using structured questionnaire. Which consisted of two sections. Reliability of the tool was elicited through internal homogenecity by using Karl Pearson correlation coefficient and it was found to be reliable r = 0.75. The pilot study was conducted on 5 industrial workers at APCPDCL industry Erragadda, Hyderabad. The knowledge levels among industrial workers on No-Scalpel Vasectomy the above average is 0 (0%) in pretest and it has been increased to 21(70%) in post-test. The average is 13(43.33%) in pretest and it has been decreased to 9(30%) in post-test, and the below average is 17(56.67%) in pretest and it has been decreased to 0(0%) in post-test. The overall knowledge score before video assisted teaching was (8.23%) mean with SD(1.25) and it was increased to (17.13%) mean with SD (2.44) and the paired ‘t’ value was 18.25 significance at 0.001 level This shows that there is a significant difference between the knowledge level on No-Scalpel Vasectomy before and after Video Assisted Teaching. The results showed that there is no significant association between pretest knowledge on No-Scalpel Vasectomy with selected demographic variables.
