Subject: Error corrected in the Household Food Security Status – Modified version derived variable, FSCDHFS2
Product(s) affected: 2007, 2008, 2007-2008 Share and Master microdata files.
Year(s) affected: 2007, 2008 and 2007-2008
Description of the problem(s):
Some households with children were improperly classified as moderately food insecure but should have been classified as severely food insecure as a result of a specification error. The error was corrected starting with the CCHS 2009 data.
Suggested correction(s): To recalculate this derived variable for 2007, 2008 and 2007-2008, please use the specifications below.
Correction steps: The correction is highlighted and in bold font.
[DHHTDKS = 1 and
(2 <= FSCASUM <= 5) and
(2 <= FSCCSUM <= 4)] or
(((2 <= FSCASUM <= 5) and( FSCCSUM <= 4)) or
(( FSCASUM <= 5) and(2 <= FSCCSUM <= 4)))]
or [DHHTDKS = 0 and
(2 <= FSCASUM <= 5)]

Subject: Error wth the flow of some answers in question CCC_Q073
Product(s) affected: 2008 Share and Master microdata files.
Year(s) affected: 2008
Description of the problem(s):
Respondents who answered question CCC_Q073 as “2 – No”, “Refusal” or “Don’t Know” skipped to question CCC_Q081, while they should have flowed to condition CCC_C073A.
Therefore, respondents who did not take medication for hypertension are automatically excluded from the universe of questions CCC_Q073A and CCC_Q073B.
Suggested correction(s): The error was corrected starting with the CCHS 2009 data.

Correction process:
- Create a temporary file including the variables in column A.
- Rename the variables in column A to temporary variables based on the corresponding variables in column B (e.g. BRX_16M to BRX_16N_00, and HMC_10D to HMC_10C_00, etc.).
- Rename the temporary variables (e.g. BRX_16N_00, HMC_10C_00, etc.) to the correct variables as indicated in column B (e.g. BRX_16N, HMC_10C, etc.).
- Combine the temporary file which now includes the variables with their correct values with the main data file.

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.

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
