Appendix A-Detailed Research Methodology
Leger is pleased to submit this methodological report to the Public Health Agency of Canada (PHAC) of a quantitative survey assessing seasonal influenza vaccination coverage among the Canadian population.
This report was prepared by Leger following the awarding of a contract to PHAC (contract number 6D034-193001/001/CY, awarded August 7, 2019).
For several years now, PHAC has been conducting a study at the beginning of the year on the uptake of seasonal influenza vaccination in the Canadian population. This study has multiple research objectives. The survey covers a variety of elements and topics. This year, some secondary objectives were added to the study while other items covered in previous years were removed from the study.
The primary objective of the research was to provide national influenza immunization coverage estimates, and in particular, estimates of seasonal vaccine uptake in three community-dwelling (non-institutionalized) groups: adults 18-64 years of age; adults 65 years of age and older; and adults with a chronic medical condition.
Secondary research objectives include:
The survey results allow PHAC to monitor and evaluate vaccination programs during the flu seasons. They also identify factors that influence influenza vaccine uptake and sub-populations with low immunization coverage. This information is important for the development of targeted programs or strategies to improve immunization coverage of unvaccinated and under-vaccinated populations.
The quantitative research consisted of telephone interviews, which were conducted using a computer-assisted telephone interviewing system (CATI technology).
Data collection for this survey took place between January 10 and February 18, 2020. The national response rate for the survey was 17.2%. The comprehensive distribution of calls is presented in Appendix A. A pre-test of 32 interviews, in both official languages, was conducted between January 9 and 10, 2020. More specifically, 15 interviews were conducted in French and 17 in English. The interviews lasted an average of twelve minutes. The interviews were recorded to assess the level of understanding of each issue in the population.
To obtain reliable data for each of the subgroups, we surveyed a total sample of 3,026 Canadian adults in all regions of the country. Only one adult respondent was interviewed per household. The national margin of error for this survey is +/- 1.78%, 19 times out of 20.
The main target population in this study was Canadian adults aged 18 and older. As was the case in previous years, the final analysis of the study focuses on 3 different target groups:
A proportion of the interviews were conducted with a sample of cell-phone numbers (cell-phone-only household members), in order to provide an adequate and reliable sample of the youth cohort (18 to 34). While the cell-phone sample will not exclusively target the youth cohort, this age group will be over-indexed in that target sample. The other interviews were conducted with landline users. According to 2016 national census data from Statistics Canada, Leger weighted the results of this survey by age, gender, region, language (mother tongue) and education level.
Leger meets the strictest quantitative research guidelines. The questionnaire was prepared in accordance with the Standards for the Conduct of Government of Canada Public Opinion Research-Series B-Fieldwork and Data Tabulation for Telephone Surveys.
Details on the methodology, Leger's quality control mechanisms, the questionnaire, and the weighting procedures are provided in the appendix.
The opinions and observations expressed in this document do not reflect those of the Public Health Agency of Canada. This report was compiled by Leger based on research conducted specifically for this project. This research is probabilistic; the results can be applied to the general population of Canada. The research was designed with this objective in mind.
I hereby certify, as chief agent of Leger, that the deliverables are in full compliance with the neutrality requirements of the Policy on Communications and Federal Identity and the Directive on the Management of Communications-Appendix C (Appendix C: Mandatory Procedures for Public Opinion Research).
Specifically, the deliverables do not include information on electoral voting intentions, political party preferences, party positions, or the assessment of the performance of a political party or its leaders.

For tracking and comparability purposes, the methodology used for this survey was the same as that of previous waves of surveys. Leger used the same methods as those used in the 2018-2019 survey with respect to sampling methodology, data collection methods and some elements of the questionnaire.
The quantitative research consisted of telephone interviews, which were conducted using a computer-assisted telephone interviewing system (CATI technology). This approach is the most suitable for assessing seasonal influenza vaccination coverage among different subgroups of the Canadian population, while ensuring a high level of representativeness.
Leger meets the strictest quantitative research guidelines. The survey questionnaire was prepared in accordance with the Standards for the Conduct of Government of Canada Public Opinion Research-Series B-Fieldwork and Data Tabulation for Telephone Surveys.
Respondents were assured of the voluntary and confidential nature of the approach, and the anonymity of their responses. As with all research conducted by Leger, any information that could identify respondents was removed from the data, in accordance with Canada's Privacy Act.
Research interviews were conducted from the Montréal call centre, which has three separate divisions: one made up exclusively of English-speaking interviewers, another exclusively of French-speaking interviewers, and the last of bilingual interviewers. These divisions ensure that all telephone surveys can easily be conducted in either official language. Interviews in English were also conducted from the Winnipeg call centre.
Data collection for this survey was conducted between January 10 and February 18, 2020. The national response rate for the survey was 17.2%. The comprehensive distribution of calls is presented below. A pre-test of 32 interviews, in both official languages, was conducted between January 9 and 10, 2020. More specifically, 15 interviews were conducted in French and 17 in English. The interviews lasted an average of twelve minutes. This pre-test allowed some adjustments to be made to the questionnaire. Another test was conducted prior to the full launch of data collection in January to confirm that all changes were properly implemented.
Results from the pre-test were not included in the coverage calculations.
To obtain reliable data for each of the subgroups, we surveyed a total sample of 3,026 Canadian adults in all regions of the country. Only one adult respondent was interviewed per household. The national margin of error for this survey is +/- 1.78%, 19 times out of 20.
Representative sample of approximately 3,000 Canadians
A sample of Canadian adults was selected using a stratified regional sampling approach. Flexible regional quotas were applied to ensure that a sufficient number of interviews were conducted in each region of Canada.
The following table details the regional quotas for the 3,000 Canadian adults and the effective distribution of the 3,026 respondents:
Table 1. Flexible regional quotas
Region | Quotas | Number of completed interviews |
---|---|---|
Atlantic | Between 220 and 260 | 243 |
Quebec | Between 720 and 780 | 749 |
Ontario | Between 890 and 1,090 | 984 |
Manitoba and Saskatchewan | Between 220 and 260 | 246 |
Alberta | Between 340 and 380 | 370 |
British Columbia | Between 400 and 440 | 434 |
Nunavut | 15 | 15 |
Northwest Territories | 15 | 15 |
Yukon Territories | 15 | 12 |
Total | 3,000 | 3,026 |
Landline telephone numbers were generated, and only cell phone numbers were purchased [1] using a stratified regional sampling approach. Telephone interviews were conducted using Leger's computer-assisted telephone interviewing system (CATI technology). This system manages the sampling electronically, by selecting and randomly dialing the phone number to call. To ensure perfect coverage of a population, the sample included residential telephone numbers located in all of Canada's provinces and territories, as well as the cell phone numbers of Canadians who do not have a residential landline (i.e., pre-validated cell numbers only). Flexible quotas were established to ensure a sufficient number of interviews in each region of Canada. In addition to these regional quotas, data was collected to ensure proper distribution of respondents by gender (men and women) and language (English and French), using flexible quotas.
Canada-wide sampling: Households with a landline
We defined a Canada-wide sample of telephone numbers. All numbers were randomly selected to generate this basic sample. Each telephone number in this sampling frame was associated with a Canadian province. Subsequently, we used this Canada-wide sample to randomly select numbers by province or region, in proportion with the provincial or regional quotas established for the project.
Canada-wide sampling: households with a cell phone number only
For the portion of the sample composed of " cell phone only households," candidates were randomly selected for each province or region taking into account provincial or regional quotas. Based on the Canadian Radio-television and Telecommunications Commission (CRTC)'s 2017 communications monitoring report, which revealed that 36% of Canadian households used a cell phone exclusively, Leger ensured that the final sample coming from cell phone numbers only closely matched this proportion.
Among the 3,026 interviews conducted as part of this project, 929 were conducted with respondents from households using only a cell phone. This represents 30.7% of the final sample, which is slightly lower than CRTC's estimate of 36% of Canadian households without landlines. Statistical weighting corrects the small difference between the sample and the actual proportion in the population.
A low response rate compromises the reliability and validity of a survey. Based on their experience in surveying various populations, Leger has established the following methods to maximize response rates:
The overall response rate for this study is 17.2%. The response rate is calculated using the following formula: (Completed interviews + Out of sample) / (Total sample - Invalid sample). This is the former Marketing Research and Intelligence Association's standard calculation method for the response rate of a telephone survey. The table below provides details of the calculation.
Base Sample | 37,622 |
Invalid sample | 4,691 |
No service | 4,421 |
Non-residential | 121 |
Fax / modem / pager | 145 |
Double | 4 |
Numbers outside of sample | 2,641 |
Language Barrier | 526 |
Unqualified | 2,114 |
Quota attained | 1 |
EFFECTIVE SAMPLE* | 30,290 |
Non-completed interviews | 27,264 |
Refusal | 4,727 |
No answer | 10,646 |
Answering machine | 8,576 |
Line busy | 324 |
Incomplete | 305 |
Appointment | 2,686 |
COMPLETED INTERVIEWS | 3,026 |
Response rate | 17.2% |
*Note that the effective sample is calculated using the following formula: Non-completed interviews + Completed interviews
An effective response rate of 17.2% is the average for a national telephone survey of 3,026 respondents conducted over a period of approximately five weeks. This rate is consistent with similar surveys. The latest data on participation rates for telephone surveys is from 2004 and shows an average response rate of 17%. Considering the decline of this survey technique in favour of the Web, a response rate of 17.2% in 2020 is a good rate. The response rate here is within the telephone industry's standard for a survey of the general population.
Weighting
According to Statistics Canada's 2016 national census data, Leger weighted the results of this survey by age, gender, region, language (mother tongue) and education level. In addition, the weighting of respondents in the cell phone-only sample was also controlled to match the 32.5% of Canadian households without landlines.
A baseline comparison of weighted and unweighted samples was also conducted to identify potential non-response biases that could be introduced by lower response rates in some demographic subgroups (see tables in the next section). As is usually the case for a telephone survey targeting mainly households with a landline, it was more difficult to reach young respondents and parents of young children. To compensate for this, Leger conducted 929 interviews with individuals whose homes do not have landlines (called on their cell phones). Through this procedure, we found that the size of our unweighted sample was very close to that of the weighted sample, calculated using the most recent data from Statistics Canada.
The table below shows the geographical distribution of respondents, before and after weighting. There is almost no geographical distribution imbalance in the unweighted sample. The weighting process mainly adjusted the weighting of Ontario-which were slightly underrepresented in the sample- as well as the weighting of Saskatchewan, Nunavut, Yukon and the North-West Territories which were overrepresented.
Province or territory | Unweighted | Weighted |
---|---|---|
Newfoundland and Labrador | 56 | 46 |
Prince Edward Island | 18 | 12 |
Nova Scotia | 106 | 82 |
New Brunswick | 63 | 66 |
Quebec | 749 | 710 |
Ontario | 984 | 1,158 |
Manitoba | 88 | 106 |
Saskatchewan | 146 | 91 |
Alberta | 355 | 338 |
British Columbia | 419 | 409 |
Nunavut | 15 | 3 |
Northwest Territories | 15 | 3 |
Yukon | 12 | 2 |
The tables below illustrate the demographic distribution of respondents by gender, age, language (mother tongue), education and household income.
First, with respect to gender, we can see that the weighting adjusted the proportion of female respondents to male respondents, with women still slightly over-represented in telephone surveys.
GENDER | Unweighted | Weighted |
---|---|---|
Male | 1,320 | 1,458 |
Female | 1,694 | 1,556 |
Other | 8 | 8 |
Refusal | 4 | 4 |
With respect to age distribution, the unweighted sample far exceeds the Public Health Agency of Canada's expectations, which requires that at least 50% of the sample comprise people aged 18 to 64 years. The final weighting of the results has corrected some minor imbalances regarding age groups.
AGE | Unweighted | Weighted |
---|---|---|
From 18 to 24 years old | 181 | 273 |
From 25 to 34 years old | 455 | 552 |
From 35 to 44 years old | 466 | 489 |
From 45 to 54 years old | 512 | 543 |
From 55 to 64 years old | 622 | 529 |
From 65 to 74 years old | 501 | 384 |
75 years old and older | 289 | 256 |
Minor imbalances in language distribution have been corrected through weighting, as shown below.
LANGUAGE (MOTHER TONGUE) | Unweighted | Weighted |
---|---|---|
French | 718 | 629 |
English | 1,890 | 1,970 |
Other | 411 | 421 |
Refusal | 7 | 6 |
The relatively small size of the weighting factors and differences in the responses of the various subgroups suggest that the quality of the data was not affected by the process. The weighting applied corrected the original imbalance for data analysis purposes; no further manipulation was required.
As with all research conducted by Leger, contact information was kept completely confidential, and any information that could identify respondents was removed from the data, in accordance with Canada's Privacy Act.
Certain subgroups tend to be underrepresented or overrepresented in a sample compared to the general population. The weighting of a sample makes it possible to correct for differences in the representation of the various subgroups of that sample compared to what is usually observed in the overall study population. Weighting factors are therefore the weight given to each respondent that corresponds to a subgroup of the sample.
The following tables illustrate the proportion allocated to each target in the sample.
