Abstract : An experimental study to identify the effectiveness of Video assisted teaching (VAT) on knowledge and pre-procedural anxiety level of patients undergoing mammography was conducted in Amrita Institute of Medical Sciences and Research Centre, Kochi. The objectives of the study were to 1) evaluate the effectiveness of video assisted teaching on knowledge among patients undergoing mammography, 2) evaluate the effectiveness of video assisted teaching on pre procedural anxiety among patients undergoing mammography, 3) find the association between knowledge among patients undergoing mammography and selected demographic variables, 4) find the association between pre procedural anxiety among patients undergoing mammography and selected demographic variables. The hypotheses of the study were H01: There is no significant difference in the knowledge level of patients undergoing mammography before and after the administration of Video assisted teaching between the experimental group and control group. H02: There is no significant difference in the pre procedural anxiety level of patients undergoing mammography before and after the administration of Video assisted teaching between the experimental group and control group. Research methodology: The design used for the study was true experimental design. The study was conducted among 60 subjects (30 each in experimental and control group) who met the eligibility criteria using simple random sampling. The demographic data and level of knowledge regarding mammography were assessed using structured questionnaire, data regarding the level of anxiety related to mammography was assessed using Becks anxiety inventory. Results: Breast self examination were occasionally performed by 14(46.7%) women in the experimental group and 3(10%) in the control group. Majority of the patients both in the experimental 18(60%) and control group 17 (56.7%) received information regarding mammography through mass media. The mean post test knowledge score (19.06) of the subjects in the experimental group was significantly higher (p<0.001) than the mean post test knowledge score (6.3) of control group. Hence the null hypothesis was rejected and alternative hypothesis was accepted, with the inference that video assisted teaching was effective in improving the knowledge on mammography. The mean post test anxiety score (17.4) of the subjects in the experimental group was significantly lower (p<0.001) than the mean pre test anxiety score (27.24) of control group. Hence the null hypothesis was rejected and alternative hypothesis was accepted, with the inference that video assisted teaching was effective in reducing pre procedural anxiety level of patients undergoing mammography. The level of knowledge on mammography was significantly higher among educated (p<0.001), employed (p 0.002<0.05), residing in urban area (p 0.016< 0.05), breast self examination (p 0.002< 0.01) and previous knowledge on mammography (p 0.035<0.05). The pre procedural anxiety on mammography was significantly higher among patients with family history of breast cancer (p 0.047< 0.05) and family history of other cancer (p 0.007 < 0.01). Conclusion: With proper education, knowledge on mammography can be enhanced and anxiety can be reduced. Creating an awareness among the mothers undergoing mammography will not only help them to undergo the procedure at the earliest but also will help in transferring their knowledge to a similar group, ultimately resulting in early detection and control of breast cancer.
