Executive Summary

A. Background and Objectives

Vaccines have proven to be an effective tool to reduce or eliminate diseases. An examination of Canadian cases has shown that routine childhood vaccines have eliminated polio, reduced the observed cases of measles, mumps, rubella, and diphtheria by 99%, and reduced cases of whooping cough by 87%[i]. Surveillance data, however, suggests that vaccine coverage in Canada is uneven.

The childhood National Immunization Coverage Survey (cNICS) measures the immunization status of the general population of children in Canada and collects data on parental knowledge of vaccines and the diseases they prevent. The cNICS helps to determine coverage and changes in update of recommended immunization schedules, provides international organizations with estimates of coverage of specific vaccines, and provides information on parent and guardian knowledge and beliefs about vaccines[ii].

The data produced from the cNICS is limited in the ability to provide information from children in all age ranges, and from key at-risk populations. Further, the COVID-19 pandemic has increased the discussion of vaccines and shifted the knowledge, attitudes and beliefs of some Canadians. The prevalence of vaccine hesitancy and refusal of COVID-19 vaccines for some has resulted in the need to understand the implications on childhood immunization coverage, and any education support needed to promote continued vaccination among children.

The Public Health Agency of Canada (PHAC) intends to address data coverage gaps related to at-risk populations through a new surveillance initiative: the Childhood Immunization Coverage Survey Among Key At-Risk Populations (KPCICS) in Canada. As a result of indications that there has been a high prevalence of vaccine hesitancy for COVID-19 vaccines among health care workers, this study was conducted among health care workers who are parents, legal guardians, or persons most knowledgeable for a child or children aged 17 or younger.

Study Objectives

This survey provides up-to-date childhood vaccine coverage data specific to health care workers who have children. The opinions and views of parents, guardians, or persons most knowledgeable collected will help to inform the following areas:

Specifically, the surveillance project collected information on:

B. Methodology

The survey sample includes 486 respondents who indicated that they are 18 years of age or older; work or volunteer in health care including in a hospital, a health clinic, a long-term care or nursing home, or in another community setting; and are also a parent or legal guardian or person responsible for health decisions for a child 17 years of age and younger. Eligible parents indicated the number of children 17 years of age and younger that they are a parent, legal guardian or person most knowledgeable for. One child was then randomly selected as the child that the parent would complete the survey about. All analyses provided herein are in regard to immunization experiences relating to the randomly selected child.

The primary sample source used was our in-house Probit panel of randomly recruited Canadians. The survey was intended to be administered online among eligible participants recruited from the panel, though a proportion of participants was to be recruited through telephone if the panel source was not sufficient to achieve the intended sample size. Because we did not expect that our in-house panel would be sufficient to complete the number of cases required, we supplemented our in-house panel sample with a nationally representative sample, including landlines selected through random digit dialing (RDD), as well as cell phone sample in a 30%:70% ratio. The screened sub-sample completed the survey by telephone. Although the original intent was to include 550 respondents in the final sample, we collected 486 but were unable to collect the remaining 64 responses with health care workers (HCWs).

We assumed that approximately 125 cases would be completed online based on telephone recruitment, however, 195 of the 486 were completely by telephone in order to maximize the sample of completed cases (179 completed with panel members and 16 completed with members of the general public through RDD sample). Sixty percent of the sample (n=291) was completed online by panel members. Each panel member received one initial email invitation and up to three email reminders. About half of sampled panel members received between one and four follow-up telephone calls, although many received up to nine calls over the course of six weeks.

The Probit panel is assembled using an RDD process for sampling from a blended land-line cellphone frame, which provides full coverage of Canadians with telephone access. The distribution of the recruitment process is meant to mirror the actual population in Canada (as defined by Statistics Canada). As such, our more than 120,000 member panel can be considered representative of the general public in Canada (meaning the incidence of a given target population within our panel very closely resembles the public at large) and margins of error can be applied. All households/individuals in the Probit panel are contacted by telephone, the nature of the panel is explained in greater detail (as are our privacy policies), and demographic information is collected. At this time, the online/off-line as well as landline/cellphone status is ascertained in order to determine the method of completing surveys (i.e., online, telephone, or mail). Ongoing activities take place several times each year to monitor, maintain, and refresh the panel. These activities include review of data quality and participation rates, and ongoing recruitment of new panel members.

The online survey was conducted between March 30 and June 1, 2023. Appendix A provides details on the characteristics of the sample. The randomly recruited probability sample carries with it a margin of error[iii] of +/-4.5%. The margin of error for most segments within the sample for which results were isolated is between +/-5% and +/-9%[iv]. Results were not isolated for segments with fewer than 10 responses to ensure that confidentiality was not compromised, and due to higher imprecision (i.e., margin of error) associated with small sample sizes. The primary sample source was an in-house Probit panel of randomly recruited Canadians[v]. The survey instrument was delivered online as well as by telephone and available in both official languages. The average length of the survey was 13 minutes online and 19 minutes by telephone. The overall response rate for the survey was 24%. Appendix A presents further details on the methodology for the survey.

The survey sample was weighted based on Statistics Canada 2021 Census population figures for highest level of education among HCWs' [vi], as well as provincial/territorial distribution of HCWs using information from the Canadian Institute on Health Information (health-workforce-canada-2017-2021)[vii]. The sample is also weighted based on the age and sex at birth of the selected child using Statistics Canada 2021 Census population figures for the general public[viii] since no population figures were available for age and gender of children of parents who are HCWs.

C. Key Findings

Respondents to the survey were comprised of health care providers who are parents. One in five are allied health workers (21%), a nurse or nurse practitioner (19%), or a community health worker (18%). More than one in 10 (13%) are in an administrative, support or managerial role. Parents in the sample are primarily between 35 and 54 years of age (76%) and three in five (61%) are women.

Health care workers who are parents were asked for their description of their physical and mental health using a five-point scale from poor to excellent. Physical health was rated more strongly than mental health where 91% described their physical health as good to excellent, compared to 80% for mental health.

Childhood Vaccination

Among all parents in the sample, 97% indicated that their child had received at least some of the recommended vaccines for their age, with 66% reporting that they received all of the recommended vaccines. Among the parents indicating that their child had received "some" (but not "all") of the recommended vaccines for the child's age, those not received were most commonly the vaccine for influenza (52%), Human Papillomavirus (HPV) vaccine (32%), or the Hepatitis A and B vaccine (30%). One in five children who had received only "some" recommended vaccines for their age group did not receive the rotavirus (22%), chickenpox (21%) or Rubella (21%) vaccines.

The majority of parents (68%) said they did not encounter any obstacles that made it more difficult to get their child vaccinated. Difficulty booking time for the appointment was noted by 10% of parents. Between five and six percent of parents noted a child's fear of needles, parental opposition or issues with access to health care. Among parents whose child did not receive one or more of the recommended vaccines, more than one in three (37%) said they did not consider one or more of the recommended vaccines to be necessary.

The primary reason stated by parents for immunizing their child is to protect their child themselves, and others from disease (76%). More than half indicated that the benefits are more important than the risks (56%) or that they received advice from their doctor or health care professional (54%).

Thirteen percent of all parents said that they are or have been hesitant in the past about their child receiving one or more of the recommended vaccines. Among these parents, 68% have concerns about the safety of the vaccine or side effects, 35% mistrust vaccine related information, and 33% have concerns about the effectiveness of the vaccine.

COVID-19 Vaccination

Seven in 10 parents indicated that their child has received a COVID-19 vaccine; including 7% who received one dose, 35% received two doses, and 28% with three or more doses. Parents reported a multitude of reasons for vaccinating their child against COVID-19, including to protect themselves and/or household members against COVID-19 infection and/or severe outcomes (72%). Nearly six in 10 said their child received a COVID-19 vaccine based on public health recommendations (59%) or to prevent the spread of COVID-19 in their community (57%). Half of parents said their child received a COVID-19 vaccine to protect themselves against long COVID (50%). Slightly fewer than half indicated it was to help restore a more normal life (47%) and more than one in three (38%) said it was because the COVID-19 vaccine was recommended by a health care professional. Over one in three parents (37%) are or have been hesitant to vaccinate their child against COVID-19; the majority indicated this is because of concerns that not enough research on the vaccine has been done on children (69%), or for concerns of the safety of the vaccine and/or side effects (56%).

Views about Vaccination

Prior to the COVID-19 pandemic, 95% of parents who are health care workers believed that vaccines were safe and effective for children. In general, 29% of parents agree that their views about vaccines have changed since the pandemic. However, the vast majority continue to believe it is true that childhood vaccines are effective (94%) or safe (93%). Nine in 10 (89%) parents will continue to get their child vaccinated with the recommended childhood routine vaccines in the future, while much fewer (59%) will get their child vaccinated with the COVID-19 vaccine.

Parents were asked to react to a battery of positive and negative statements about childhood immunizations. In terms of reactions to positive statements, 95% of parents agree that vaccines help protect their child's health and 92% of parents agree that having their child vaccinated protects others in the family and community. More than eight in 10 (83%) parents also agree that unvaccinated children are at higher risk of getting some serious diseases, including COVID-19. More than three in four (77%) parents agree that delaying childhood vaccines causes risk to their child's health and the same proportion (77%) believe that most parents have their child vaccinated.

When considering negative statements, 85% of parents disagree that the use of alternative practices such as homeopathy or naturopathy can eliminate the need for vaccination. About the same proportion (82%) disagree that a healthy lifestyle can replace the need for vaccination, although 14% agree. While eight in 10 parents (79%) also disagree that children receive too many vaccinations overall, one in five (18%) agree with this view. Just over seven in 10 (73%) parents disagree that it is better to develop immunity from having a disease rather than from a vaccine; however, close to one in four (21%) agree. About the same proportion of parents agree that children receive too many vaccines at the same visit (24%).

Sources of Childhood Immunization Information

Most parents said they would be most likely to consult the Public Health Agency of Canada or Health Canada (72%), or health care providers (71%) in order to find information about childhood immunization. Half or more would consult their local public health unit or clinic (59%), scientific publications and journals (58%), the Ministry of Health within their province or territory (54%), or international organizations (50%), and the National Advisory Committee on Immunization (NACI) was mentioned by 42%. More than one in three (39%) parents would consult with community nursing stations or clinics. Other sources include the news or media (16%), family and friends (16%) or social media (6%).

D. Note to Readers

Detailed findings are presented in the sections that follow. Overall results are presented in the main portion of the narrative and are typically supported by graphic or tabular presentation of results. The programmed survey instrument can be found in Appendix B.

It should be noted that the survey asks a number of questions about behaviours that may have a tendency to exert pressure to respond in a socially desirable way for respondents to under-report their attitudes and behaviours related to vaccine hesitancy[ix]. Results for the proportion of respondents in the sample who either said "don't know" or did not provide a response are not indicated in the graphic representation of the results of survey questions where multiple resources were possible, particularly where they are not sizable (i.e., 10% or less). Results may also not total 100% due to rounding or where multiple responses could be provided.

Characteristics of the Sample

As shown in Table 3 (Appendix A), parents in the sample are typically between 35 and 54 years of age, and 61% describe themselves as women. Nine in 10 (89%) are the birth parent, and 96% live with the child (primary or secondary residence).

Respondents in the sample are generally educated and affluent. Although 10% do not have post-secondary education, 30% have a college level of education, and 54% have a university certificate, diploma or degree. Just under one in three (31%) indicated their household income to be under $100,000 (for the year ending December 31, 2022); however, 27% said it is between $100,000 and $150,000, and 31% reported it to be more than $150,000.

Families in the sample are found in all regions, generally reflecting the population density of Canadians across the country. Eleven per cent live in a rural community.

Parents responding to the survey were asked to indicate the number of children, as well as ages of the children in the household. In households with more than one child, one of the children was randomly selected in order to enable parents or guardians to respond to specific questions about immunization. One in five (21%) respondents selected a child in the household who is under five years of age, while 38% indicated the age of the selected child to be between five and 12 years of age and 38% selected a child who is 12 to 17. The sex at birth of the selected child is male in 51% of cases and female in 49% of cases.

Parents were asked for their description of their physical and mental health using a five-point scale from poor to excellent. Results suggest that parents' physical health is reasonably good with only 7% describing it as only fair. Another 39% described it as good, 37% said it is very good and 15% rate it as excellent. Parents' description of their mental health, however, is not as positive, with 20% rating it as "fair" to "poor", 30% rating it as "good" and the other half rating it as "very good" (34%) or "excellent" (16%).

Vaccination Status

Among all parents in the sample, 97% indicated that their (randomly selected) child had ever been vaccinated. Two percent said that their child had not been vaccinated and the remaining few respondents preferred not to answer or said they did not know. Among the 97% who said their child had been vaccinated at some point, 66% indicated that they received all of the recommended vaccines for the child's age. One in three (33%) said that they had received some of the recommended vaccines.

Among the parents indicating that their child had received "some" (but not "all") of the recommended routine vaccines for the child's age, half (52%) of parents said the child had not received the vaccine for influenza[x]. About three in 10 parents of children five years of age or older said the child had not received the Human Papillomavirus (HPV) vaccine (32%). About the same percentage of parents of children who are six months of age or older (30%) said the child did not receive the Hepatitis A and B vaccine. The Hepatitis B vaccine had not been received by 27% of children who have not received "all" vaccines for their age. Among children who had not received "some" or "all" recommended routine vaccines for their age group, 22% did not receive rotavirus, 21% did not receive chickenpox and 21% did not receive Rubella vaccines. Between 15% and 18% missed one of the other vaccines noted in Table 1, below.

Obstacles to Vaccination

Parents were also asked what obstacles, if any, they encountered that made it difficult to get their child vaccinated. Two in three parents (68%) said they did not encounter any obstacles, including 75% of parents reporting that their child received all recommended vaccines for their age, and 57% of parents reporting that their child did receive some of the recommended vaccines. Difficulty booking time for the appointment was noted by 10% of parents, including 13% of parents who reported that their children received all recommended vaccines and 6% among parents reporting that only "some" vaccines were received. Overall, between five and six percent of all parents sampled noted a child's fear of needles, parental opposition or issues with access to health care were obstacles to receiving vaccination. Focusing exclusively on parents who reported one or more obstacles, 33% indicated difficulty booking an appointment; 20% mentioned their child's fear of needles, 16% noted parent opposition, and 17% noted access issues.

Reasons for Not Immunizing

Among parents indicating that their child has received "some" of the recommended routine vaccines, more than one in three (37%) said they did not consider one or more of the recommended vaccines to be necessary[xi]. One in five (20%) said that one or more of the recommended vaccines is not offered or their child is not eligible to receive it, and 14% indicated concerns about the risk of side effects. Another 11% said they were not aware that one or more of the vaccines are important for their child to receive, and 7% expressed concerns about the effectiveness of one or more of the vaccines.

Reasons for Immunizing

Among the parents who said their child received "some" or "all" of the recommended routine childhood vaccines, protection of their child and others from disease was the most often noted reason (76%). Half of parents said that they vaccinated their child because the benefits outweigh the risks (56%) and based on the advice of a doctor (54%). About one in five said that it was a requirement for school or daycare (21%), or they feared they might regret it later (18%). Fewer said this was because they knew someone who got a vaccine-preventable disease (14%), or they were following the advice of a friend or family member (9%).

Reasons for COVID-19 Immunization

The primary reason parents decided for their child to receive the COVID-19 vaccine is to protect themselves and/or household members against COVID-19 infection and/or severe outcomes (72%). Nearly six in 10 said their child received a COVID-19 vaccine based on public health recommendations (59%) or to prevent the spread of COVID-19 in their community (57%). Half said it was to protect themselves against long COVID (50%). Slightly fewer indicated it was to help restore a more normal life (47%). Over one in three said their decision was because the COVID-19 vaccine was recommended by a health care professional (38%).

COVID-19 Vaccine Hesitancy

The majority of parents (59%) are not or have not been hesitant to vaccinate their child against COVID-19, while 37% said they are or have been hesitant. Looking at vaccine hesitancy among the full sample of parents, (regardless of hesitancy for recommended childhood vaccines or the COVID-19 vaccines), only 59% of parents are not or have not been hesitant about either recommended or COVID-19 vaccines. Eleven percent are or have been hesitant about both recommended vaccines and the COVID-19 vaccine. Three percent are or have been hesitant about recommended vaccines alone (but not the COVID-19 vaccine). One in four parents (27%), however, are or have been hesitant about the COVID-19 vaccines, even though they are not and have not been hesitant about recommended vaccines.

Among parents who are or were hesitant to vaccinate their child against COVID-19, two in three (69%) said this was because of concerns that not enough research has been done in children. More than half (56%) are concerned about the safety of COVID-19 vaccines and/or the side effects. More than two in five (43%) cited concerns about the effectiveness of the COVID-19 vaccines. One in three or less felt that the COVID-19 vaccine was not necessary (32%), mistrust COVID-19 vaccine-related information (26%), believe their child is not at risk of getting COVID-19 or at risk of severe infection (20%), or wanted to first discuss COVID-19 vaccines with their child's health care practitioner (10%).

C. Views about Vaccination

Changes in Views about Safety and Effectiveness of Vaccines due to COVID-19 Pandemic

Prior to the COVID-19 pandemic, 95% of parents who are health care workers believed that vaccines were safe and effective for children. Only five percent believed vaccines were unsafe and three percent believed they were not effective.

Current Views about Safety and Effectiveness of Vaccines

Unlike views about COVID-19 vaccines, health care worker parents do not seem to have changed their views about vaccines in general; 94% said it is true that vaccines are effective and 93% said vaccines are safe. The COVID-19 vaccines, however, are only considered to be safe among 74% of parents, with 14% believing them to be unsafe and another 11% saying they are unsure. Only two in three (68%) parents believe the COVID-19 vaccines to be effective, while 19% do not believe them to be effective and 12% are unsure.

With regard to the other five statements posed about childhood immunizations, 85% of parents disagree that the use of alternative practices such as homeopathy or naturopathy can eliminate the need for vaccination, although 9% agree. About the same proportion (82%) also disagree that a healthy lifestyle can replace the need for vaccination, although 14% agree. While eight in 10 parents (79%) also disagree that children receive too many vaccinations overall, in this case one in five (18%) agree with this view. Just over seven in 10 (73%) parents disagree with the view that it is better to develop immunity from having a disease rather than from a vaccine; however, close to one in four (21%) agree. About the same proportion of parents agree that children receive too many vaccines at the same visit (24%), even though 72% disagree.

Summary, Conclusions and Recommendations

A. Summary

Recommended Vaccines

One in eight parents said they are or have been hesitant about at least one of the recommended routine childhood vaccines for their child (excluding COVID-19 vaccines). Reasons include concerns for side effects (68%), a mistrust of the available vaccine-related information or not knowing where to get reliable info (35%), and a lack of faith in the effectiveness of vaccines (33%).

Nine in ten parents said that they will obtain recommended vaccines (excluding COVID-19 vaccines) for their child in the future, although 5% will not and 4% are unsure or did not provide a response.

In spite of this, one in three parents reported that their child has received only "some" but not "all" recommended childhood vaccines for their age. The vaccines most often not received are influenza (offered annually), and HPV, followed by meningococcal, pneumococcal and MMRV.

COVID-19 vaccine

A much higher proportion of parents (37%) are or have been hesitant about the COVID-19 vaccine compared with the extent of hesitance about routine childhood recommended vaccines (13%). Across all parents, eight percent are or have been hesitant about both the recommended vaccines and the COVID-19 vaccine. Eleven per cent are or have been hesitant about recommended vaccines, but not the COVID-19 vaccine. One in four parents (26%), however, are or have been hesitant about the COVID-19 vaccine, even though they are not or have not been hesitant about recommended vaccines. Only half of parents (55%) are not or have not been hesitant about recommended or COVID-19 vaccines.

Three in ten parents reported that their child did not receive any doses of the COVID-19 vaccine. More than nine in 10 children aged 12 to 17 received at least one dose.

Only six in ten parents said that they will obtain (further) COVID-19 vaccines for their child in the future.

Views about Vaccines

Three in ten parents have changed their view about vaccines since the pandemic, although there is little difference reported in the current versus pre-pandemic views about the safety and effectiveness of recommended vaccines. There is considerably greater concern expressed about the safety and effectiveness of the COVID-19 vaccine than there is about recommended vaccines, with only 74% saying that the COVID-19 vaccines are safe and 68% saying they are effective (compared with 93% and 94% saying the same about recommended childhood vaccines).

The most prevalent arguments for vaccinating children, agreed upon by most parents, is the need to protect the health of the child (95%), to help protect others (92%), and to mitigate the risk of more serious illness (83%).

There is a sizable proportion of parents who are concerned about the potential for side effects from vaccines (41%).

Considerable proportions of parents have reported agreeing that there are too many vaccines in a single visit (24%), there are too many vaccines in general (18%) and that it is better to develop immunity from getting a disease (21%).

Preferred Sources of Information

The most preferred sources for information about vaccines for parents are the PHAC/HC (72%) and health care providers (71%). These top two sources are followed by local health units (59%), and provincial/territorial ministries of health (54%). Although scientific journals are in the middle of the second tier of sources at 58%, they are preferred by the largest concentration of hesitant parents (61%); preferred by slightly more hesitant parents than prefer health care providers, and considerably more than prefer the PHAC/HC as sources for information about child vaccines.

B. Conclusions

Although one in eight parents reported hesitance to vaccinate their child with recommended routine childhood vaccines, fewer said they would not obtain recommended vaccines in the future (5%), but significantly higher numbers of parents reported that their child had not been vaccinated with "all" recommended vaccines in the past.

Views regarding the COVID-19 vaccine are much more cautious than they are for recommended childhood vaccines. Reasons for hesitance against COVID-19 vaccines suggest that the newness of the vaccines, the speed at which it was developed and researched, as well as the mandatory nature of its roll out and messaging were obstacles to acceptance for some parents, magnifying their existing concerns about the risk of side effects of vaccines.

The impact of the COVID-19 vaccine seems to be contained to this vaccine itself and has not had a significant impact on views and intent regarding recommended routine childhood vaccines, which still remain positive with regard to safety and effectiveness, although some still consider "some" recommended vaccines to be "less necessary" than others.

C. Limitations of the Research

The sample size for the survey serves as a limitation to the level of precision and ability to detect differences between sub-groups (e.g., based on age of the selected child). Given the low incidence of the population defined in the study, consideration could be given to broadening the population of health care workers to capture a larger proportion of the population of parents or decision-makers for children 17 years or younger.

There was a lower-than-expected proportion of health care works with less than a Bachelor's degree captured in the sample, either because of a lower proportion found in the panel used or a lower propensity to respond among this segment. Similarly, there was a lower-than-expected number of parents selecting a child under the age of five years of age. This may be because of a lower proportion of health care workers with younger children in the panel, or a lower propensity of parents with younger children to participate in the survey.

Appendices

A. Methodological Details

The summary section of this report (Sub-heading B - Methodology) described the Probit panel which was the primary source used for the sample[xii]. The survey is comprised of 486 completed cases of Canadians, working or volunteering in the area of health care, who is 18 years of age or older and a parent, guardian or person with decision-making authority for someone 17 years of age and younger.

As outlined in the Executive Summary, the survey was collected between March 30 and June 1, 2023, with a questionnaire length averaging 13 minutes online and 19 minutes by telephone. Respondents were informed in the invitation that all responses are completely confidential, and no responses will be linked to personal information. This randomly recruited probability sample carries with it a margin of error of +/-4.5% at a 95% confidence interval. The margin of error for each of the target groups is between 5% and 14%.

As shown in Table 3, the average response rate overall across the 486 cases is 24%. It is 22% among Probit sample members who completed the survey online. A total of 20,348 records were sampled to receive an email invitation to the survey, of which 93 were undeliverable, leaving a valid sample of 20,255. Of these records, 291 were completed and 4,217 were found to be out of scope (i.e., ineligible). These two combined (4,508) are divided by the valid sample of 20,255 to obtain the 22.3% response rate.

A slight majority of the sample (n=291) was collected through online self-administration, however, 40% was collected by trained, bilingual interviewers. The response rate is 30.3% across cases completed by telephone based on 195 completed and 1,061 found to be out of scope, out of the valid 4,131 records. Table 3 summarizes the outcomes for each of the online and telephone methods of administration.

The database was reviewed following data collection for data quality, outliers, coding requirements, weighting and construction of independent variables, and was used to explore sub-group patterns (e.g., by age and gender of the selected child, education and region of the parent as well as key vaccine-related indicators provided by parents) in the analysis. Review and cleaning of the data involved a review of the branching logic, deleting any extraneous responses from respondents as a result of backtracking through the survey to correct their answers[xiv]. A second step involved variable creation to merge responses from several multi-select questions. These included two versions of question 11 (reasons for vaccine hesitancy) into a single harmonized set of responses; merging multiple variables related to age of the selected child to create a single age variable; removing programming language from the question and response category labels; recoding responses as needed to created combined or collapsed categories of responses (e.g., several points on a scale); and creating a regional variable based on the first three digits of the postal code reported by parents[xv].

A Random Iterative Method (RIM) weight was calculated using crosstabulation software to correct for response bias between the population distribution of the final sample of completed interviews. Weighting was based on age and sex at birth of the selected child using 2021 Census data for the general public[xvi], as well as on parent education based on education level of HCWs (Census 2021 data[xvii]) and region of HCWs in Canada (CIHI figures for 2021). To calculate a RIM weight, crosstabulation software reconciles the differences between the sample and the target distributions across a user-defined set of, typically demographic, variables through a series of random iterations, until it arrives at a weighting factor for each record that adjusts the population distribution of the data file to most closely match the target population. Only completed interviews used in the final data set were considered in the development of the weight. Eight records in the final sample had missing information for one or more of the four variables used in the weight, and were therefore assigned a weight of "1". A total of 311 of the 486 completed cases in the data set have a weight value of less than 1, 22 have a value of 1, 75 have a value of between 1.01 and 1.49, and 48 have a value of between 1.5 and 2.0. Only 17 records have a value of between 2.01 and 3.0 and 11 have a value above 3.0. Table 4 provides the unweighted and weighted distributions of the variables used in the calculation of the weight.

In terms of non-response bias, although it is difficult to assess the presence of non-response bias since information about why non-responders did not participate is usually unavailable, a comparison of the unweighted sample with 2016 Census figures from Statistics Canada for health care workers indicates an underrepresentation of those with less than a university level of education. There is a more educated sample in the survey than found in the population with 70% reporting university degrees, compared with 47% in the general population. There is also a modest overrepresentation in Quebec (30% compared with 23% in the population), and an underrepresentation in British Columbia (9% compared with 12% in the population and Alberta (10% compared with 13% in the population).

B. Banner Tables

Two banners were created for the purposes of sub-group analysis. The first features results for the complete set of parents responding to a question, along with comparisons of results for:

The second banner features results for the complete set of parents responding to a question, along with comparisons of results for:

In each of these sets of comparisons, parents indicating "Don't know" or "Prefer not to answer" are excluded from the comparison (i.e., not included in any of the sub-sets of parents), although results for these parents are included in the total for the question. All numbers of respondents are presented unweighted, while all percentages are shown as a weighted percentage, rounded to the nearest whole number (i.e.,.4 or lower was rounded down and.5 or higher was rounded up) in the results displayed in the banner tables and presented in the report. Results were suppressed where sub-groups included fewer than 10 respondents, indicated with "X". In questions allowing for multiple responses, "Don't know" and "Prefer not to answer" were only allowable if no other responses were selected. All categories of responses indicated in CAPS were added as a result of post-collection coding; these response options were not present in lists at the time of collection. Segments are tested against the pool of other segments shown in the specific table. Statistical testing used is Chi2. Statistically significant cells are also noted with plus signs (significantly higher) and minuses (significantly lower) at the level of.05 or higher. Caution should be used in interpreting results based on fewer than 30 respondents given reduced precision of estimates.
