Study process

The study process followed a number of stages through design, data collection and analysis

Online questionnaire

An online questionnaire was created to collect quantitative data using Likert scales and multiple-choice questions. Data were analysed using SPSS.

Remote interviews

Interviews were conducted remotely and then transcribed and coded using NVivo to look for common themes.


Results from testing the new prototype showed the improvements were generally successful in improving the utility, usability and engagement of the website. However, the improvement in performance was significantly greater for younger people (18 -39 years old) than older people (40 – 65+ years old). It’s therefore recommended a longitudinal study with a bigger sample size should be undertaken to understand if the differences found between age groups are significant over a longer use time.
