A naturaldisaster is a major adverseevent resulting from natural processes of the Earth; examples include floods, volcaniceruptions, earthquakes, tsunamis, and other geologic processes. A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population’s resilience, or ability to recover. So the researcher selected a study to assess the effectiveness of information booklet on knowledge regarding Natural Disaster Preparedness among adults. Objectives: • To assess the knowledge regarding natural disaster preparedness among  adults (age group of 21-35 year).  •  To provide information booklet regarding natural disaster preparedness to  adults (age group of 21-35 year).  • To assess the post test knowledge regarding natural disaster preparedness  among adults (age group of 21-35 year).  • To assess the effectiveness of information booklet regarding natural disaster   preparedness among adults. • To find out the association between knowledge and selected socio-demograhic  variables. Aims: To assess the effectiveness of information booklet on knowledge regarding natural disaster preparedness among adults residing in selected area of Bhopal. Settings and Design: Research design adopted for this study one group pre-test and post test design judge the effects of the treatment by the differences between the pre-test and post test scores without comparing with a control group In this study the investigator selected Indrapuri area of Bhopal. The sample were selected by non- probability convenient sampling technique. The adult’s male and female who are under 21-35 years had selected for the study  Methods and Material: The research approach adopted was Quantitative research approach. Research design was Pre-experimental one group pre-test post-test design. Non probability convenient sampling technique was used in the study. The sample consisted of 60 adults residing in selected area of Bhopal. The tool used for the data collection was structured knowledge questionnaire.  Statistical analysis used:  • Before the administration of information booklet, only (9) of the participants  had good knowledge, (30) of the adult had average knowledge and (21) had  poor knowledge. The pre-test mean score was 19.3 and after the administration  of information booklet, the post test mean score was showed 25.2. • The overall mean score of knowledge increased from 19.3 to 25.2.  • The post test mean score of knowledge of 25.2 was comparably more than  the pre test mean score of 19.3 and it was found to be statistically significant  (t-value=18.27, p<0.0001) at 0.05 level, i.e. p<0.05. Results: Finding related to the socio demographic variables of adults was found that majority of adults 36.4% aged 21-25year were females, Regarding Majority i.e. 31.7% were High School. In reference to source of information on Natural Disaster   Preparednessmost of the adults i.e. 35% had heard from Mass media. Finding related to the effectiveness of information booklet on Natural Disaster Preparedness among the adults was found out through paired ‘t’ test (t=18.27) at p<0.0001. According to the mean was there was significant difference between pre test and post test knowledge score was increased from 19.3 to 25.2 after administering information booklet.  Finding related to the section wise difference between pre-test and post-test knowledge score according to mean there was significant section wise difference between pre-test and post-test. In disaster (section-1) knowledge score increased from 17.6 to 23.3. In earthquake (section-2) knowledge score increased from 16 to 22.4. In flood (section-3) knowledge score increased from 18-23. In tsunami (section-4) knowledge score increased from 18.25 to 23.5. In disaster management (section-5) knowledge score increased from 16.6 to 22.3 after administering the Information Booklet.  Conclusions: On the basis of the finding, the investigator concluded that the Information Booklet is significantly effective on improving the knowledge regarding Natural Disaster Preparedness among adults. Hence the adults should be encouraged to attend health education programme.
