General Social Survey Cycle 26 Variables

Question

I have a few questions regarding the General Social Survey Cycle 26 Variables:


1) Variable HUI_EMO1
-Value 3 is “Somewhat unhappy”
-Value 4 is “Somewhat unhappy”
-What is the difference between these codes?

2) Variable HLTH_UTIL_INDEX
-Does the index provide a measure of overall health (what is it an index of)?
-Is a lower score “better” or “worse”?

3) General
-We don’t seem to have the documentation on how derived variables were created: is this available?
-Section 6.4 of the user guide indicates: “The data dictionary identifies which variables were derived and the nature of their derivation.” Normally this is more than the names of the variables which were used to derive the variable.
-My French is somewhat suspect, but should the title on the first page of the Guide d’utilisatuer (C26_FMGD_Guide_d'utilisateur.pdf) be "données et reçus" rather than "données at reçus"?"

Answers (in red italics)

1) Variable HUI_EMO1 (this has to be fixed)
-Value 3 is “Somewhat unhappy”
-Value 4 is “Somewhat unhappy” should be : unhappy with little interest in life


3) Variable HLTH_UTIL_INDEX
-Does the index provide a measure of overall health (what is it an index of)?
-Is a lower score “better” or “worse”? the HUI is described in the Guide under the section on Health and Well-being in the Guide.
-Here are links and a definition of the HUI which was prepared by CCHS (we use the same version of the HUI in GSS):

The Health Utilities Index (HLTH_UTIL_INDEX) provides a description of an individual’s overall functional health, based on eight attributes: vision, hearing, speech, mobility (ability to get around), dexterity (ability to use hands and fingers), emotion (feelings), cognition (memory and thinking) and pain. For more information on the origin and calculation of this index, please refer to the Canadian Community Health Survey (CCHS), 2007, Derived Variable (DV) Specifications at: http://www.statcan.gc.ca/imdb-bmdi/document/3226_D2_T9_V4-eng.pdf or HUI3 or “Single-Attribute Utility Functions” and “HUI3 Multi-Attribute Utility Function” at: http://www.healthutilities.com/hui3.htm.

French

L’indice de l’état de santé (HLTH_UTIL_INDEX) donne une description de la santé fonctionnelle globale d’une personne fondée sur huit attributs, à savoir la vision, l’ouïe, la parole, la marche (capacité à se déplacer), la dextérité (usage des mains et des doigts), l’émotion (sentiments), la cognition (mémoire et pensée) et la douleur. Pour plus d’informations ou une explication détaillée du calcul de cet indice, consulter à L’Enquête sur la santé dans les collectivités canadiennes (ESCC), 2007, Spécifications des variables dérivées (VD) à : http://www.statcan.gc.ca/imdb-bmdi/document/3226_D2_T9_V4-fra.pdf ou “Single-Attribute Utility Functions” and “HUI3 Multi-Attribute Utility Function” at: http://www.healthutilities.com/hui3.htm."

-We don’t seem to have the documentation on how derived variables were created: is this available?
-Section 6.4 of the user guide indicates “The data dictionary identifies which variables were derived and the nature of their derivation.” Normally this is more than the names of the variables which were used to derive the variable. Unfortunately, we do not have more details in the data dictionary on how we derived the variables. However, we do have the source of each derived variable. Should you need more details on a specific variable, please let us know and we can send you more information.
-My French is somewhat suspect, but should the title on the first page of the Guide d’utilisatuer (C26_FMGD_Guide_d'utilisateur.pdf) be "données et reçus" rather than "données at reçus?" We will fix this on the CD.
