Statistical methods / analysis
Using the Raosoft sample size calculator, a sample size of 385 participants was obtained (using a confidence interval of 95%, margin of error 5% and power of 80%).

Considering an additional 20% to this sample size to account for incomplete data (n = 392), the
target sample size would be 400.

Data analysis will be carried out using SPSS (Statistical Package for Social Sciences) using a confidence interval of 95% and P-value of 0.05.
Multivariate analysis would be performed using the independent variables including age, gender, level of education, concurrent health problems and the dependent variables including the risk perception as rated on the 5-point Likert-scale.

Summary
Brief summary
The flu is a viral illness that affects many people every year around the world. The World Health Organisation (WHO) categorises the flu as one of the 10 biggest threats to human health in 2019. As it is spread from person to person, attempts to reduce the number of people that get infected is important. This is even more important when lots of people unexpectedly become very sick at the same time, and many of those who become sick die..

The study aims to investigate how and what people decide is a risk to their health. In particular, whether people see influenza (‘the flu’) as a major risk or not, and what things are taken into consideration. The information we collect will be used to see if there are any patterns in the decisions people make and maybe why.

If we can better understand what people know about the flu and how bad they think it is or can be, it could help to improve public education and hopefully reduce the chance of people catching it or becoming very sick with the flu in the future.

We will ask 400 people to take-part and complete a questionnaire, which should take no more than 10 minutes. All answers will be completely anonymous and unidentifiable. Once the study has been finished, the results can be shared with everyone who took part if they wish.
