Study type
Interventional
Description of intervention(s) / exposure
Participants will be required to give consent for the researchers to access your Healthy Brain Ageing clinic assessment records. From this researchers will populate a personalised dementia risk profile. Participants will receive an email with their personal dementia risk profile (pdf format) within two weeks. The personal risk profile is based on their HBA clinic assessment. A short online questionnaire about knowledge of dementia risk, motivation to engage in dementia risk reduction, and distress will be asked pre and post being provided the dementia risk profile.

Participants will also be given the option to participate in a telephone interview to debrief and provide us with additional feedback, which will be audio recorded.

Outcomes

Dementia risk knowledge

To asses the overall dementia risk knowledge two survey questions will be asked 1) the perceived susceptibility and 2) the knowledge of risk reduction.

- To assess for perceived susceptibility, participants will be asked “How likely is it do you think that you will get Alzheimer’s disease in your lifetime?” The answer can range from 0 to 100, where 0=certain not to happen and 100=certain to happen.
At follow up, to examine accuracy of perceived risk, the participant’s perceived risk will be subtracted from their actual risk estimate. Positive values indicate underestimation of risk while negative values indicate overestimation of risk. Scores will be then recorded into a dichotomous variable (less than or equal to +/-10% vs greater than or to +/-10%), indicating whether perceived risk was similar to the predicted risk.
- To assess knowledge of risk reduction, we have included the knowledge of dementia risk and protective factors questionnaire and added extra risk and protective factors identified in the Lancet commission for dementia prevention. Questions from an Australian community survey will be used to assess top 5 things they can do to reduce risk, and confidence in risk reduction.

Psychological effects
- The K10 is a commonly used screening scale for non-specific psychological distress validated for use in Australia. The K10 has also been demonstrated as having moderate sensitivity to symptoms change in an Australian sample. Scores on the K10 range from 10 to 50, and a score of 30 or more indicates severe level of distress.
- The Dementia Worry Scale is used to assess dementia worry. It has strong internal consistency and test-retest reliability. It consists of 12 items with scores ranging from 15 to 60.

User evaluation
- We adapted a five-point scale (from 1= not at all to 5= completely) previously used to assess user experience of a dementia information website, participants are asked whether the information provided was engaging, easy to understand, how helpful they found the risk profile, and how much they felt they learned (from 1=nothing at all to 5=a great deal). Additionally, participants are asked: Do you feel you need more information about your dementia risk profile? [yes / no] and are given the option to discuss their experience of using the risk profile with a researcher in a telephone interview.
