Abstract

Introduction: Respiratory viral diseases are disease of respiratory system caused by respiratory viruses. Respiratory viruses are the most frequent causative agents of diseases in humans with significant impact on morbidity and mortality worldwide. In present study we assessed the effectiveness of self-instructional module on knowledge regarding respiratory viral diseases and its prevention among adolescents in selected schools at Perinthalmanna. Methodology: Quantitative one group pre-test post-test approach was used in this study. 60 samples were selected by using non probability convenient sampling technique. Structured knowledge questionnaire including demographic variables was used for the study. Result: Pre-test result shows that 29(48.33%) of adolescents had good knowledge, 27(45%) of adolescents had average knowledge and 4(6.67%) of adolescents had poor knowledge. Post-test knowledge shows that 38(63.34%) had excellent knowledge, 20(33.33%) had good knowledge, 2(3.33%) had average knowledge and none of the adolescent had poor knowledge. The effectiveness of self-instructional module was assessed by paired ‘t’ test. The calculated value was (t=19.3047) higher than the table value (t59=2.0010), it shows the self-instructional module was effective. There was no association between pre-test knowledge score of adolescents with selected demographic variables such as age, gender, class, religion, education of mother, education of father, occupation of father, occupation of mother. There was a significant association found between pretest knowledge score of adolescents with values of previous source of knowledge. The mean post-test score (15.03) was higher than the mean pre-test knowledge score (9.17). Conclusion: The present study revealed that the self-instructional module was effective as it improved the knowledge level of post-test.
