Breast feeding immediately after delivery encourages the “bonding” of the mother to her infant. Initiation of breastfeeding, it is the first contact and first breastfeed. Objectives- To assess the knowledge and practice of primipara postnatal mothers regarding breast feeding technique in terms of pre and post –test scores in experimental groups and control groups. To evaluate the effectiveness of the video assisted teaching programme by comparing pre –test and post test knowledge and practice scores. To assess the correlation between knowledge and practice. Methodology-.A quantitative approach and quasi-experimental research design (pre-test, post-test, control group) was used for the study. Sample size was 60 primi para postnatal mothers 30 in control group and 30 in experiment group and sampling technique used was non probability sampling (Purposive sampling) technique Independent variables video assisted teaching breast feeding technique. Self Structured Knowledge Questionnaire was prepared with 40 questions and observation checklist for practice Questionnaire was prepared with 30 questions to collect the data and data was analyzed by descriptive and inferential statistics. Results-In pre test experimental group 17(56.7%) , 13(43.3%) had average ,good knowledge and none of them having below average and very good knowledge . In post test experimental group 20(66.7%), 8(26.7%) and 2(6.7%) good , very good average knowledge and none of them having below average. In pre - test control group 19(63.3%), 11(36.7%) had average, good knowledge and none of them having below and very good knowledge. In post - test control group 15(50.0%), 15(50.0%) average, good knowledge and none of them having below average and very good knowledge In pretest experimental group 24 (80.0%), 6(20.0%) had adequate, inadequate practice. In pretest control group 17(56.7%), 13(43.3%) had inadequate moderate adequate practice regarding. In post -test experimental group 23 (76.7%),7(23.3%) had adequate moderate adequate practice and0(0%)had inadequate practice. In pretest control group 19(63.3%) 11(36.7%) had moderate inadequate practice and 0 (.0%) had adequate practice The comparing pre and post test knowledge and practice in experimental group was found in the pre test 20.27 ± 3.45 and post test 28.50 ± 3.79.the pre vs post paired t ‘test value 36.877.In control group on knowledge was found in the pre test 19.97± 3.01 and post test 0.767± 0.86 pre vs post paired t ‘test value 4.892. In experimental group on practice score of mothers was found in the pre test 14.60 ± 3.69 and post test 22.90 ± 3.60. the pre vs post paired t ‘ test value 28.027.In control group on practice score of mothers was found in the pre test 11.43±3.29 and post test 12,20±.49 .The pre vs post paired t ‘ test value 6.185.There was no correlation coefficients were not significant in pre-post knowledge and practice in experiment and control group.
