1. Background

As announced in the 2019 Budget, the Public Health Agency of Canada (PHAC) has received $50 million over five years, starting in 2019–20 and ending in March 2024, to support key elements of the implementation of Canada's first national dementia strategy.

The Public Health Agency of Canada (PHAC) has implemented a social marketing strategy to support dementia prevention and stigma reduction. A two-pronged, phased approach was adopted by focusing first on reducing stigma and increasing awareness of dementia in general, followed by risk reduction awareness and the introduction of healthy lifestyle behaviours.

The focus of the 2023-24 activities focused primarily on risk prevention by continuing to provide information about the various dementia risk factors and the healthy lifestyle actions Canadians can take to help reduce their risk.

Research shows that many Canadians are not aware that there are risk factors for dementia, that a person can take simple actions to help reduce their risk and that dementia, contrary to a popular belief, is actually rarely genetic. The ad campaign messaging aims to generate awareness of the risk factors and in tandem show a simple and accessible action Canadians can take to lower their risk. The desired outcome is that people, having another good reason to take better care of their health, will be motivated to adhere to healthier life behaviours and ultimately reduce their risk of many chronic health conditions and diseases.

A digital campaign showcasing two prominent risk factors ran from February to March 2024. The same messaging may be used again on a larger scale to reach a larger population.

The advertising campaign target audiences are:

2. Research Objectives

The Government's Policy on Communications and Federal Identity requires the evaluation of advertising campaigns exceeding $1 million in media buy using the Advertising Campaign Evaluation Tool (ACET). The ACET was created in 2002 following a Cabinet directive identifying the need for a standard advertising evaluation approach across departments. The main objectives were to bring rigor and consistency to ad campaign evaluation and to develop norms on metrics against which campaigns could be evaluated.

The objectives of the research were as follows:

The results of this research will allow HC and PHAC to evaluate the performance of this campaign. It will also help HC and PHAC to improve any future phases of the campaign (or similar).

Target Audience

The survey will be conducted with adults 25+ with a skew to at risk populations:

3. Methodology

3.1 Data collection

This project involved two (2) online surveys – a baseline survey and a post-campaign survey. Both surveys were executed online using a non-probability online panel. This is the standard approach for all Government of Canada advertising evaluation surveys. The initial baseline survey was conducted before the campaign launched and the post-campaign survey was conducted following the completion of the campaign.

The surveys were conducted in English and French, with respondents being able to complete in either language of their choice. The baseline survey was 8 minutes in length and had 3 open-ended questions. It was mostly based on the established ACET questionnaire, with some campaign specific questions (supplied by Health Canada). The post ACET was 11 minutes in length and had 5 open-ended questions.

The survey platform was Accessibility for Ontarians with Disabilities Act (AODA) compliant according to Web Content Accessibility Guidelines (WCAG2.0AA). Survey panelists had means to communicate their specific accessibility needs to enable survey participation via email. The survey invitation included the Canadian Research Insights Council (CRIC) survey registration number so that survey respondents had the ability to verify the legitimacy of the survey as a research initiative sponsored by the Government of Canada. Survey respondents were informed of their rights under the Privacy Act, the Personal Information Protection and Electronic Documents Act, and the Access to Information Act, and that respondents' rights were protected throughout the research process.

For the baseline survey a pre-test was conducted on October 23rd, 2023, with 42 completes (20 English / 22 French), to confirm survey length before fully deploying the questionnaire. An open-ended question was asked at the end of the survey where any problems with the clarity of the survey questions could be brought to our attention; no issues were flagged. The survey was fully launched and ran between October 23rd, 2023, and November 1st, 2023. For the post-campaign survey, a pre-test was conducted on February 1st, 2024, with 39 completes (19 English / 20 French). No issues were flagged. The survey was fully launched and ran between February 1st and February 16th, 2024.

3.2 Sample Frame

The baseline survey was conducted with a sample of n=2,007 Canadians ages 25+ and the post-campaign survey was conducted with a sample of n=2,019 Canadians ages 25+. For both surveys, quotas were set to ensure representation by region, age, and gender, according to the latest Census information.

For both surveys, quotas were set to ensure representation by region, age, and gender, according to the latest Census information. In both surveys, we observed a natural fall out of the target groups of Canadians 25+ with a skew to at-risk populations. These groups were identified using the following questions:

Living with existing and/or prone to a health condition:

Are you currently living with or are you prone to the following health conditions due to risk factors such as genetics or lifestyle? (Select all that apply)

Living with unhealthy behaviours:

In a typical week, how often, if at all, do you have a drink containing alcohol? Enter number of drinks per week. Allowable range 0-50

Target: >10 per week for women and >15 for men

In a typical week, how often, if at all, do you engage in physical activity? Enter number of hours per week. Allowable range 0-70

Target: 1 hour or less per week

In a typical week, how often, if at all, do you smoke cigarettes (include other tobacco products)? Enter number of days per week you smoke at least one. Allowable range 0-7

Target: 7

The following table provides the unweighted sample sizes achieved for the target group.

3.3 Participant Recruitment

Sample Source

Ipsos partnered with Canadian Viewpoint Inc., on the fieldwork and in obtaining the required sample Canadian Viewpoint has one of the largest consumer panels at ~300,000 active panelists. Like Ipsos, Canadian Viewpoint uses mixed-mode strategies (phone/online/in-person) to build its panel permitting more representative samples. Canadian Viewpoint's online consumer panel is also recruited using post screeners during telephone surveys, Facebook, online vetted list and during in-person studies. Incentives are not used for recruitment purposes to ensure quality, but respondents are incentivized for completing survey directly proportionate to the amount of time taken to complete the survey and with comparable incentives offered by other online panel sources.

The comprehensive background profiling data gathered when respondents join a panel allows for the targeting of respondents based on key criteria, such as region, age, gender, education and income level, intention to buy a home within 12 months, profession, and other characteristics.

The data excludes any duplicate respondents based on IP capture and excludes panelists who have completed another Government of Canada survey in the previous 30 days as a member of that panel.

Sample Weighting

The table below shows the unweighted and weighted distributions of the online sample. Weighting was applied to the sample to ensure that the final data reflects the general adult population by region, age, and gender according to the 2021 Census. A Random Iterative Method (RIM) technique was applied for weighting. Note: totals may not add to 100% due to rounding.

The figures presented in the table above show minimal differences between the unweighted and weighted samples, except for males aged 25-34. As a result of the strong representativeness of the unweighted data the largest weight factor that was applied for any respondent is 2.5.

Email Statistics

For this survey, a non-probability sample was used. Therefore, a response rate cannot be calculated.

However, the participation rate for the baseline survey was 96% and post-campaign survey was 88%. The post-campaign rate is lower because more cases were excluded based on having completed a similar survey within 30 days or the baseline ACET wave. Participation rate is calculated as follows: Participation Rate = R/(R+IS+U).

Completions Baseline Survey Post-campaign Survey
Invalid Cases 309 700
Unresolved (U) 0 0
In-scope non-responding (IS) 112 395
Responding units (R) 2397 2976
Participation Rate 96% 88%

Online survey cases can be broken down into four broad categories:

Invalid Cases

These can include only clearly invalid cases (for example, invitations mistakenly sent to people who did not qualify for the study, incomplete or missing email addresses in a client-supplied list).

Unresolved (U)

These include all the cases where it cannot be established whether the invitation was sent to an eligible or an ineligible respondent or unit (for example, when email invitations bounce back or remain without an answer before the candidate could be qualified).

In-scope non-responding (IS)

These include all refusals, either implicit or explicit; all non-contacts and early break-offs of known eligible cases; and other eligible non-respondents (due to illness, leave of absence, vacation or other).

Responding units (R)

These include cases who have participated but who were disqualified afterwards (for example, when admissible quotas have been reached). It also includes all completed surveys or partially completed surveys that meet the criteria set by the researcher to be included in the analysis of the data.

Unresolved (U), in-scope (IS), and responding units (R) are all included in the broad category of "potentially eligible" cases. However, invalid cases are not included in the calculation of outcome rates.

For this survey a router was used to screen potential respondents and assign them to one of several surveys. Given this, it is not possible to estimate the number of cases "invited" to participate and whether they were eligible or not. Therefore, it is not possible to estimate the "unresolved" cases. For this survey, responding units is broken out as follows.

Completions Baseline Survey Post-campaign Survey
- Over quota 390 957
- Qualified Completes 2007 2019
Responding units (R) 2397 2976

The sample routing technology uses weighted randomization to assign surveys to participants. Upon entry into the system, panelists are checked to ensure they have not exceeded survey participation limits. A list of potential survey matches is determined for each panelist based upon the information we know about them. Panelists may be asked additional screening questions within the system to ensure they meet the project criteria. Priority may be given to surveys that are behind schedule; however, this is kept to a minimum as survey randomization must remain in place as a key element for preventing bias. In this case, limited prioritization was applied during the field window, therefore there is a low chance of sample bias.

Non-Response Analysis

The results of this survey are not statistically projectable to the target population because the sampling method used does not ensure that the sample represents the target population with a known margin of sampling error. Reported percentages are not generalizable to any group other than the sample studied, and therefore no formal statistical inferences can be drawn between the sample results and the broader target population it may be intended to reflect. The data have been weighted to reflect the demographic composition of Canadian adults aged 25 years and over.

The table below compares the unweighted survey samples to the 2021 Census results by region, age, and gender. Overall, the sample is highly representative of the national adult population.
