Interpreting Estimates from the Redesigned Canadian Community Health Survey (CCHS)

By Steven Thomas, senior methodologist, CCHS
and Sylvain Tremblay, senior analyst, CCHS

Abstract

In its attempt to better address user needs and to make better use of the interviewer resources, the regional component of the Canadian Community Health Survey , or the .1 survey, was redesigned to include varying types of content and to collect data continually over time. This change in structure allows for the collection and dissemination of various types of information for various time periods for estimation at various geographical and socio–demographic levels. For the user, this implies that several different products will be available for several different time periods. Proper interpretation of the results is now more crucial than ever as the user will have a choice in the product that they use in their analysis. The choice of product will be based on the characteristics they wish to study and the detail required in the estimates. This paper will clarify how the redesign will impact the user and aid in the proper interpretation of the resulting estimates.

1. The CCHS Redesign

After the release of the 2005 regional component of the Canadian Community Health Survey (CCHS cycle 3.1), the CCHS was redesigned to address two main points: to better address user needs and make better use of collection resources 1. The implementation of a continuous collection technique was the key step in addressing these points. At the same time, a flexible content structure was implemented to allow for varying content to be collected over various time periods. These changes affect the dissemination strategy in the types of content that can be released as well at the frequency of releases. With these changes in place, it was decided that it was a good time to implement certain methodological improvements including the implementation of a more time–efficient process.

1.1 Changes in Collection

The change that has the largest impact on users is the change to the data collection approach of the CCHS. In the past, the CCHS regional component collected data from roughly 130,000 respondents over a 12–month period every two years. Starting in January 2007, data are now continually from roughly 65,000 respondents throughout each year. To ensure that the sample is collected continuously, a new sample of roughly 11,000 respondents is collected every two months where each sample is representative at the health region level for the specific time period. Samples collected in the Territories are representative of the population after 12 months.

1.2 Changes in Content

With the change to a continuous collection approach, it is now possible to collect various types of information (or content) over various time periods. The duration of collection depends on the characteristics of interest and the sample size required. For prevalent characteristics and general domains, the content only needs to be collected for a short time–period before there are enough respondents to produce a quality estimate. For less prevalent characteristics and more detailed domains, the content is collected over an extended time–period in order to obtain an adequate sample of respondents.

The main CCHS content components are still categorized under common and optional content, although the common content is now split into two sub–components: core and theme. While both sub–components are asked of all CCHS respondents, the core content is meant to remain relatively stable over time and the theme content is collected for 12 or 24 months and can rotate back into collection after two, four or six years. The optional content component gives health regions the opportunity to select content that addresses their provincial or regional public health priorities. It can either be collected for one or two years before it is reviewed again.

A new component called Rapid Response is also available which allows the collection of data on emerging health issues from a small sample of respondents over two months of collection (approximately 11,000 respondents). This component, with a maximum duration of 2 minutes, is offered to cost–recovery clients with an immediate need for national–level data.

1.3 Changes in Dissemination

The changes to the collection and content structure of the CCHS have an impact on the dissemination strategy. In the past, information was disseminated every second year after collection of all respondents for the survey. Data files (Master, Share, PUMF) are available for the 2000/2001 (Cycle 1.1), 2003 (Cycle 2.1), and 2005 (Cycle 3.1) reference years. A 6–month file (allowing estimates to be calculated with 65,000 respondents) was produced from the Cycle 3.1 data collected from January 2005 to June 2005.

Beginning in June 2008, with the release of data collected during the 2007 collection period, master and share data files will be released every year. These annual data files will contain about 65,000 respondents, or half the sample size available with previous CCHS data files. These files will include core, theme and optional content collected throughout the year.

In June 2009, two main files will be made available: a main data file based on the 2008 collection period, which will be similar to the main 2007 data file, as well as a main data file based on the 2007–2008 collection period. The 2007–2008 file will be similar in size to files from the previous cycles (approximately 130,000 respondents). It will include core, optional and the theme content collected over the two–year period. One–year themes will not be available on the two–year data file. Also, theme modules collected from sub–sample of respondents will continue to be disseminated in separate files. These files include core content and sub–sample theme modules only. See table 1 for a clarification of what will be available with the 2007 and 2008 releases.

Table 1. Content components included in 2007 and 2008 data files
Files Core content 2007 Theme1 2008 Theme2 2007–2008 Theme Optional content3
2007 Main Yes N/A N/A Yes Yes
Sub–sample Yes Yes N/A No No
2008 Main Yes N/A Yes4 Yes Yes
Sub–sample Yes N/A Yes5 No No
2007–2008 Main Yes No No Yes Yes
1The 2007 theme was comprised of three modules (Patient satisfaction, Access to health care services and Waiting times) which were all asked to a sub–sample of respondents.
2The 2008 theme is formed of a group of modules related to chronic disease screening and a module on measured height and weight. This last module is asked of a sub–sample of respondents.
3This assumes that optional content remains the same for the two years. If not, it will only be included in the file of the year in which it was collected.
4Chronic disease screening.
5Measured height and weight.

In addition to the regular files, rapid response files will be produced for cost–recovery clients. These files will be available to other users upon request and will contain the rapid response content along with core content for a 2–month period.

Public–use Microdata Files (PUMFs) will be released every second year based on two years of collection. The first PUMF will be released Summer 2009 based on the 2007–2008 collection period. Single year PUMFs will not be available.

1.4 Changes in Survey Methodology

With the changes to the collection, content and dissemination strategies, certain changes were made to the methodology used in calculating survey weights. The redesign meant that weights would be produced more frequently and a methodology consistent with continuous collection was required. This evolution was also seen as an opportunity to make certain improvements to the weight adjustments that are used in the process2.

1.4.1 Period weighting

The weights are controlled, as best possible, to ensure that each collection period is equally represented with the weight and the weighted respondents represent the average population for the extended period of the particular release. Estimates represent the average over the time period.

1.4.2 Changes to integration

The CCHS uses a dual frame methodology where respondents are sampled from a telephone list frame and an area frame. Weights are adjusted / integrated to ensure that the population is represented only once. In the past, the weights on the telephone frame were adjusted for undercoverage (no landline, unlisted numbers, etc.) before integration with the area frame to ensure that the area and telephone list frames covered the same population. This required the assumption that those individuals not on the telephone frame were the same as those who were.

Knowing that the characteristics of telephone respondents can differ from those from those not covered by the telephone frame, the integration method has been updated3. Now, telephone frame respondents are integrated only with those units on the area frame who are also on the telephone frame. Those respondents on the area frame who are not on the telephone frame do not have their weights adjusted. This means that for variables affected by mode of collection, the resulting estimates should be more representative of the actual population.

1.4.3 Changes to calibration

The final step of the weighting procedure is to ensure that the weights sum to known population totals through a process known as calibration. These known totals are usually at the health region by age group by sex level. It is generally accepted that by calibrating weights, estimates for totals are more precise than those not calibrated. However, in order to do a proper calibration adjustment, it is suggested to have at least 20 observations in the domain. This should not be a problem with a 2–year file but with the 1–year file it will not be possible to post–stratify in all domains because of the reduced number of respondents. Users will be provided with a list of post–stata with less than 20 observations and corresponding cells will be suppressed from tabular data produced by Statistics Canada.

2. Impact on Users

2.1 More data, more often

Starting with the release of the 2008 and 2007–2008 data in June 2009, users will have the choice of working with one–year or two–year files. Eventually, it will be possible for users to combine these standard files to produce, for example, three–year or four–year files.

2.2 Period estimation

Whether a multi–year, two–year or one–year file is being used, users are encouraged to think of CCHS data as involving period estimation, in which the interviews corresponding to a period of time are combined and an updated sampling weight calculated. An annual estimate of a given characteristic is reflective of the average characteristics of the average population for the time period. In the case of the 2007 file, estimates are reflective of the average from January to December 2007. The result is a period estimate which is different from the snapshot idea that is often presented with most cross–sectional surveys. Technically, this is true only of the Census, where estimates represent a point in time.

The idea of period estimation is simply an extension of the methods used for previous cycles of CCHS, in which a set of interviews conducted over a 12–month period were combined. Similarly, the techniques involved in combined standard one–year or two–year data sets to create customized period estimates will be very similar to those used in combining cycles 1.1, 2.1 and 3.1 of the survey4.

Decisions about which period to use in a given analysis should be guided by the level of detail and the quality required. With a one year file, estimates will not always be available because of the quality associated with the limited sample size. The CCHS recommends having a Coefficient of Variation of less than 33% and having at least 10 respondents in the domain with the characteristic before publishing an estimate. This will not be possible for rare characteristics and detailed domains with a one–year file. Instead, users will have to rely on two–year files or multi–year accumulations.

Where the use of either a one–year or two–year file is viable, the user should consider the trade–off between accuracy and currency. If it is important to reflect the current characteristics of a population as closely as possible, the one–year file would be preferable. With two–year files, year–to–year trends will be masked, just as the seasonal trends are masked in a one–year file. However, with the increased sample size, more detailed estimates and analyses can be carried out.

2.3 Impact on variable naming convention

The variable naming convention has been changed slightly to reflect the fact that the same variable is being collected each year. In the past a letter designating the cycle was included in the variable name. For example, the ‘e’ in ‘ccce_101’ meant that it was the information collected from cycle 3.1. From now on the variable will be labeled ‘ccc_101’. To help users wanting to combine two data files or more, a new variable showing the reference period “REFPER” was added. This variable uses the following format YYYYMMYYYYMM (collection start year and month – collection end year and month).

2.4 Differences in Estimates Compared to the Past

Users should be aware that changes to sampling and the production of sampling weights introduced in 2007 might partially explain differences from previous cycles. In terms of sampling, the sample is controlled to have roughly the same number of respondents collected throughout the year and controlled to ensure that half the sample is from each of the two frames. This is not a dramatic change from the previous releases where the sample was divided into monthly collection periods. In terms of the production of weights, changes made to the process of integrating telephone and area frame samples could have the effect of influencing characteristics which are strongly correlated with having a listed phone number5. Further studies of this possibility are planned.

Highlights

  • Beginning with the June 18, 2008 release, master and share data files will be released every year. These annual files will contain about 65,000 respondents or half the sample size of previous data files. Data files based on two years of data will continue to be produced and will be similar in size to files from the previous cycles (~130,000 respondents).
  • Theme content was introduced with the CCHS redesign. This content is asked of all CCHS respondents and collected for one or two years only.
  • Annual sample files will include core content, annual theme content and the 2–year theme and optional content collected that year. The two year files, will include the core content, the 2–year theme and all optional content collected for two years.
  • Beginning in June 2009, users will have a choice between using one–year or two–year files.
  • With single–year estimates, year–to–year trends can be calculated. Given the idea of continuous collection, each annual estimate is reflective of the average characteristics of the average population for the time period.
  • To estimate rarer characteristics in more detailed domains, the use of two–year files, or even multi–year accumulations, will be necessary to ensure good data quality (33% CV with minimum of 10 respondents having the characteristics).
  • The CCHS variable naming convention has been changed slightly to reflect the fact that the same variable is being collected. The letter designating the cycle (e.g., “e” for cycle 3.1) was dropped from the variable name.

Canadian Community Health Survey (CCHS)

Household weights documentation

June 2011

  1. Introduction
  2. Weighting overview
  3. Sample weighting

1. Introduction

This document describes the weighting process used in the creation of the household weight for the Canadian Community Health Survey (CCHS). In using this weight, users should note that the survey is designed to represent individuals and not designed to represent households. Certain steps are taken in the design to ensure that the sample is representative of different demographic groups and this may affect how well the sample represents households of different compositions. Also, since the calibration for the household weight is done at the provincial level, it is possible to yield reliable estimates at the national and provincial level only. It is felt that individual responses to certain questions can be used to represent the household. This weight should only be used for variables where it can be assumed that the responses from the individual clearly represent the household and that the response would not be affected by who responded within the household. This is highlighted by the fact that throughout the document, we refer to responding persons. Users must remember that the responses from this selected individual are assumed to represent the household when using the household weight.

Those familiar with the CCHS will notice that these weight adjustments are very similar to those used for other weights that have been produced in the past. A CCHS interview can be seen as a two–part process. First, the interviewer gets the complete roster of the people living within the household (Household Response). Second, (s)he interviews the selected person within the household (Person Response). In the calculation of the household weight, the individual responses are used to represent the household. Nonresponse adjustments for both stages are still included since nonresponse can occur at either part of the interview process. Note that nonresponse adjustments for the household can be based on characteristics of the individual respondent. Since the survey is designed to collect information from the individual, the characteristics of the individual can have an effect on nonresponse of the household.

2. Weighting Overview

In order for estimates produced from survey data to be representative of the covered population and not just the sample itself, users must incorporate the survey weights in their calculations. A survey weight is given to each person included in the final sample, that is, the sample of persons having answered the survey. This weight corresponds to the number of households in the entire population that are represented by the respondent.

The CCHS has recourse to three sampling frames for its sample selection: an area frame acting as the primary frame and two frames formed of telephone numbers complementing the area frame. Since only minor differences differentiate the two frames formed of telephone numbers in terms of weighting, they are treated together. They are referred to as being part of the telephone frame.

The weighting strategy treats both the area and telephone frames independently. Weights resulting from these two frames are afterwards combined into a single set of weights through a step called "integration". After some adjustments, this integrated weight becomes the final weight. Note that depending on the need, one or two frames were used for the selection of the sample within a given health region (HR). The weighting strategy deals with this aspect at the integration step.

3. Sample weighting

As mentioned previously, units from both the area and telephone frames are treated separately up to the integration step. These weighting steps for the household weight, up to and including the integration of the frames, are the same as the steps from the main weight. Please refer to the CCHS User Guide for more information about these steps. The final three weighting steps, person nonresponse, winsorization and calibration, are explained in sub–sections 3.1–3.3.

Although these two frames were used to cover the three territories, some modifications had to be done relative to their use. These modifications substantially affected the weighting of these three regions and they are reported in sub–section 3.4.

Diagram A presents an overview of the different adjustments that are part of the weighting strategy, in the order in which they are applied. A numbering system is used to identify each adjustment applied to the weight and will be used throughout the section. Letters A and T are used as prefixes to refer to adjustments applied to the units on the Area and Telephone frames respectively, while prefix I identifies adjustments applied from the Integration step onwards.

3.1 Person–level nonresponse (I2)

A CCHS interview can be seen as a two–part process. First, the interviewer gets the complete roster of the people within the household. Second, (s)he interviews the selected person. In some cases, interviewers can only get through the first part, either because they cannot get in touch with the selected person or because that selected person refuses to be interviewed. Such individuals are defined as person nonrespondents and an adjustment factor must be applied to the weights of the respondents to account for this nonresponse. Using the same methodology that was used in the treatment of household nonresponse (see User Guide, Section 8.2 – A4), the adjustment is applied within response homogeneity groups based on characteristics available for both respondents and non–respondents. All characteristics collected when creating the roster of household members are available for the creation of the groups as well as geographic information and some paradata. The scoring method is used to define the classes. In the end, the following adjustment factor is calculated within each group:

Formula 1

Weight I1 is multiplied by the above adjustment factor to produce weight I2. Nonresponding persons are dropped from the weighting process from this point onward.

3.2 Winsorization (I3)

Following the series of adjustments applied to the respondents, some units may come out with extreme weights compared with other units in the same domain of interest. For the household weights, the domains include province by household size, where household size is defined by: 1–person household, 2–person household and at least 3–person household. Some responding households could represent a large proportion of their province by household size domain or have a large impact on the variance. In order to prevent this, the weights of the outlier units that represent a large proportion of their domain are adjusted downward using a “Winsorization” trimming approach.

3.3 Calibration (I4)

The last step in obtaining the final CCHS household weight is calibration. Calibration is done using the program CALMAR to ensure that the sum of the final weights corresponds to the household estimates defined at the province by household size level. These groups of interest are defined by the sizes: 1–person household, 2–person household and at least 3–person household. At the same time, the weights are seasonally adjusted to ensure that the each two month collection period is equally represented within the sample. In terms of geography, all calibration is at the provincial level only.

The household count estimates are based on the most recent census. The average of these monthly estimates is used to calibrate for each of the province by household size post–strata within a collection period. The weight I3 is therefore adjusted to obtain the final weight I4 with the help of the adjustment factor I4 defined as follows:

Formula 2

Consequently, the weight I4 corresponds to the final CCHS household weight that can be found on the household weight file with the variable name WTS_MHH for the master weight and WTS_SHH for the share weight.

3.4 Particular aspects of the weighting in the three territories

The sampling frame used in the three territories is somewhat different from the one used in the provinces. Therefore the weighting strategy is adapted to comply with these differences. This section summarises the changes applied to the weighting steps in the territories.

For the area frame, an additional stage of selection is added in the territories where each territory is initially stratified into groups of communities and one community is selected within each group. Note that the capital of each territory forms a stratum on its own and is consequently selected automatically at this first stage. This has an effect in the computation of the probability of selection and therefore in the value of the initial weight (A0). Once the initial weight is calculated, the same series of adjustments (A1 to A4) is applied to the area frame units. The household–level adjustment classes are built in the same way as for the provinces, using the same set of variables available.

For the weighting of the telephone frame units, it should first be noted that only the RDD frame is used for the territories, and exclusively in the Yukon and Northwest Territories capitals. All of the standard telephone adjustments are applied.

The two sets of weights (area and telephone) are subsequently integrated and then adjusted for person level nonresponse, winsorization and finally calibrated in a similar way to what is done for the provinces, with the exception of four details. First, the integration is applied only to units located in the Yukon and Northwest Territories capitals since the other communities are covered only by the area frame. Second, for Nunavut, the household counts used for calibration only represent the 10 largest communities (73% of the households) because of the under–coverage of the area frame (for more details, see User Guide, section 5.4.1). Third, in the Yukon and Northwest Territories, starting with the 2008 and 2007/2008 reference periods,calibration is used to control for the proportion of households located inside the capital cities versus the proportion of households located outside of the capital cities. The same approach has been adapted for Nunavut starting in 2009. Finally, due to the differences in collection strategies, the number of collection periods used in calibration for the seasonal effect in the territories is different from the provinces. In 2009, two 6–month periods are used in the three Territories.

3.5 Creation of the Share weight (WTS_SHH)

Along with the master file and PUMF , which contain all CCHS responding persons, a share file is created which contains only a portion (>90%) of the original CCHS responding persons. The individuals on this share file have agreed to share their data with certain partners. To compensate for the loss of some respondents from the file, the weights of these "sharers" must be adjusted by the factor:

Formula 3

Similar to the nonresponse adjustments, this factor is calculated within homogeneity groups, where in this case, individuals with similar estimated propensity to share will be grouped together. The final weight after this adjustment is called WTS_SHH.

3.6 The Food Security Module in 2010

The Food Security Module (FSC) is one of the few modules that are part of the CCHS where it can be appropriate to use the household weights. For 2007–2008, the FSC module was part of the common content, and therefore was asked to respondents in all provinces and territories. For the 2009–2010 collection period, the FSC module is part of optional content and was not selected for some of the provinces. Given this change, it is no longer appropriate to calculate national estimates with variables in this module since the results would only represent those provinces and territories where the module was asked. For more information on optional content selection, please refer to the appendices of the User Guide.

To: Users of the 2005 master or share file

Subject: The household weight of the master and all share files is invalid (small error)

Product(s) affected: Household weight file hs_hhwt.txt

Year(s) affected: 2005

Description of the problem(s): The main household weight variable (WTSE_MHH on the master file and WTSE_SHH on the share file) on all the HS_HHWT.txt file is invalid and differs from their corresponding FWGT weight on the B5_HH.txt Bootstrap file.

Since Bootvar uses the variable FWGT to calculate the final estimates, any analysis on the 2005 Households weights using Bootvar would be correct and would not need to be redone. However, any preliminary analysis based only on the variables WTSE_MHH or WTSE_SHH would be incorrect and would need to be revised.

Users should know that the errors were considered minimal.

Suggested correction(s): The master and share files have been redone with the corrected household weight and are available upon request.

To: Data Users and licensees of the Canadian Community Health Survey data, Cycles 2.1 and 3.1, Public Use Microdata File

Subject: Derived variable on work stress scale – Job strain (WSTCDJST and WSTEDJST)

Cycle(s) affected:

Cycle 2.1 (optional content selected by 12 health regions within Newfoundland and Labrador, Ontario and Saskatchewan)

Cycle 3.1 (optional content selected by all health regions in Quebec and Saskatchewan).

Product(s) affected:

Derived variable on work stress scale – Job strain (WSTCDJST and WSTEDJST)

Referred to hereafter as WSTnDJST where n = C or E.

Description of the problem(s):

The Job strain scale should reflect the ratio of the psychological demands and decision making leeway in accordance with the principle that strong demands combined with weak decision making autonomy generate more stress.

Certain variables from the denominator of the WSTnDJST derived variable are incorrectly specified in the Derived Variable (DV) Specifications document for cycles 2.1 and 3.1. The data are therefore erroneous. The ratio of strong demands and decision making leeway result is scores that are too high.

Suggested correction(s):

Public use microdata file (PUMF):
Cannot be corrected by users given the fact that only the derived variables exist on the file. User support via remote access is available upon request.

Share and Master Files:
A temporary reformatting step aiming to invert certain variables must be added to the specifications for the WSTnDJST variable. The step to invert the categories (to arrange them from 4 to 0 rather than from 0 to 4) must be applied to the following variables: WSTn401, WSTn402, WSTn403, WSTn405 and WSTn409.

A “patch file” is available on request.

Corrective Pseudo–code:
The two following temporary reformatting steps are executed and then the WSTnDJST variable is created according to the DV specifications:

Step 1: Temporary Reformatting

Modify the scale of responses for the questions WSTn_401 to WSTn_406 and WSTn_409 from 1 to 5, to 0 to 4

If WSTn_401 <= 5 then WSTn_401 = (WSTn_401 – 1)
If WSTn_402 <= 5 then WSTn_402 = (WSTn_402 – 1)
If WSTn_403 <= 5 then WSTn_403 = (WSTn_403 – 1)
If WSTn_404 <= 5 then WSTn_404 = (WSTn_404 – 1)
If WSTn_405 <= 5 then WSTn_405 = (WSTn_405 – 1)
If WSTn_406 <= 5 then WSTn_406 = (WSTn_406 – 1)
If WSTn_409 <= 5 then WSTn_409 = (WSTn_409 – 1)

Step 2 : Temporary Reformatting

Invert the scale of responses for the questions WSTn_401 to WSTn_403, WSTn_405 and WSTn_409, from 0 to 4, to 4 to 0

If WSTn_401 <= 4 then WSTn_401 = (4 – WSTn_401)
If WSTn_402 <= 4 then WSTn_402 = (4 – WSTn_402)
If WSTn_403 <= 4 then WSTn_403 = (4 – WSTn_403)
If WSTn_405 <= 4 then WSTn_405 = (4 – WSTn_405)
If WSTn_409 <= 4 then WSTn_409 = (4 – WSTn_409)

Step 3:

See WSTnDJST in the Derived Variable (DV) Specifications document.

To: Data Users and licensees of the Canadian Community Health Survey data, Cycle 3.1, Public Use Microdata File (PUMF)

Subject: Derived variable documentation contains misleading information indicating that some variables are included in the PUMF when they are not.

Cycle(s) affected: Cycle 3.1

Product(s) affected:

Cycle 3.1 PUMF derived variable documentation in English (DERIVE_E.pdf) and in French (DERIVE_F.pdf).

Description of the problem(s):

The derived variable descriptions for the following modules:

  • Smoking – Cessation Aids (SCA)
  • Smoking – Nicotine dependence (NDE)
  • Smoking – Stages of change (SCH)

indicate that the derived variables are available in the PUMF, while they are not. Since these modules have only been selected by one or two territories, the information is sensitive to respondent identity disclosure and is therefore not included in the PUMF.

Suggested correction: N/A
