to assess and compare knowledge among nursing students regarding ill effects of substance abuse and its prevention before and after video based instruction and to determine the association between post test level of knowledge and demographic variables among nursing students. The hypotheses of the study were there will be significant difference in the mean score of knowledge before and after video based instruction among nursing students (H1) and there will be significant association between post test level knowledge and selected demographic variables among nursing students.(H2).
Methods: Quantitative approach, Pre-experimental one group pre-test post test study was conducted to evaluate the effectiveness of video based instruction on knowledge with 50 nursing students posted in psychiatric ward GRH at Madurai. Total enumerative sampling was used and the data was collected by structured knowledge questionnaire with paper-pencil technique before and after video based instruction. Study subjects were given with video based instruction (session comprises of aspects like concept, ill effects and prevention of substance abuse including case scenario to all samples for 30 minutes).
Statistical analysis: Paired Student ‘t’ test, Chi-square test was used to test hypotheses.
Results: Before video based instruction 1(2%), 38(76%) and 11(22%) respectively belonged to the category of poor, average and good knowledge with the mean score of 4.00, 10.89 and 18.09 and no one had very good knowledge. After intervention, 5(10%), 23(46%) and 22(44%) respectively belonged to the category of average, good and very good knowledge with the mean score of 13.40, 19.26 and 24.86 and none of them had poor knowledge. The overall pre-test mean score was 12.34 and for the post test is 21.14. There was a significant difference in the mean score of knowledge before and after video based instruction i.e. the calculated ‘t’ value was 12.595 and it was statistically significant at 0.05 level. Further there was a significant association between post test level of knowledge and place of living at 0.05 level of significance among nursing students.
Conclusion: Thus, study finding concludes that video based instruction was significantly effective to improve knowledge regarding ill effects of substance abuse and its prevention among nursing students.
