Workshops based on the psychology of behavior change and disaster preparedness done in a face-to-face manner can be used to prompt households to take action to protect themselves in case of any disasters such as earthquakes, flood or fires, reveals a new UCL-led study.
The study, published today in Nature Human Behavior, found that by engaging households in evidence-based, face-to-face workshops, researchers could engineer change in householders' natural disaster preparedness that would last long term, potentially saving lives.
Although vulnerability to natural disasters is increasing globally, even in high-risk regions few households have measures in place to protect and prepare themselves. Ill-preparedness tends to lead to larger post-disaster losses and greater loss of life, injury and displacement.
"Being prepared for multiple hazards makes households more resilient, especially given that hazards can occur simultaneously or in rapid sequence, such as the recent cyclones followed by floods in Mozambique and Zimbabwe."
UCL researchers and their local counterparts ran workshops to empower people to make small household adjustments to prepare for disasters, such as securing TVs, computers and cabinets to the walls and ensuring objects are not placed above beds regarding protection from earthquakes. They also showed the importance of keeping exits clear of obstruction and having functioning smoke detectors and in-date fire extinguishers, regarding fire protection.
The workshops were comprised of two three-hour training sessions, after which the researchers observed whether households had adopted disaster preparedness behaviors. Half of the households in the sample were given the training, and half were not.
"We found that behavioral changes were most likely where there was home ownership and high outcome expectancy - that is, when individuals had a sense of agency and believed their actions would have an effect, they were more likely to make changes," says Professor Joffe.
"An unintended consequence of the study was that even the control group - which did not receive training - improved its preparedness behavior. This suggests that when risk-related behaviors are simply being observed, householders will change their behaviors to become more prepared."
Professor Joffe concludes that face-to-face training, or even simply home observations, by external sources such as a fire department, could be a way to ensure that measures are put in place by householders across a population to prepare for natural disasters. The very idea of a disaster being 'natural' obscures how much humans can do to protect themselves from such events.
