This derived variable (ADL_der) is based on the CCHS derived variable ADLF6R which flags respondents who need help with tasks based on their response to the various activities of daily living (ADL) variables.
adl_fun(ADL_01, ADL_02, ADL_03, ADL_04, ADL_05)A derived variable (ADL_der) with 2 categories:
- Needs help with tasks
- Does not need help with tasks
The CCHS derived variable ADLF6R uses different ADL variables across the various CCHS survey cycles. This newly derived variable (ADL_der) uses ADL variables that are consistent across CCHS cycles.
In the 2001 CCHS survey cycle, the ADLF6R variable examines the following ADL variables:
ADL_01 - Needs help preparing meals
ADL_02 - Needs help getting to appointments/errands
ADL_03 - Needs help doing housework
ADL_04 - Needs help doing personal care
ADL_05 - Needs help moving inside house
ADL_07 - Needs help doing heavy household chores
In the 2003-2005 CCHS survey cycles, the ADLF6R variable examines the following ADL variables:
ADL_01 - Needs help preparing meals
ADL_02 - Needs help getting to appointments/errands
ADL_03 - Needs help doing housework
ADL_04 - Needs help doing personal care
ADL_05 - Needs help moving inside house
ADL_06 - Needs help doing finances
ADL_07 - Needs help doing heavy household chores
In the 2007-2014 CCHS survey cycles, the ADLF6R variable examines the following ADL variables:
ADL_01 - Needs help preparing meals
ADL_02 - Needs help getting to appointments/errands
ADL_03 - Needs help doing housework
ADL_04 - Needs help doing personal care
ADL_05 - Needs help moving inside house
ADL_06 - Needs help doing finances
This newly derived variable (ADL_der) uses ADL_01 to ADL_05 which are consistent across all survey cycles. For any single CCHS survey year, it is appropriate to use ADLF6R. ADL_der is recommended when using multiple survey cycles.
# Using adl_fun() to create ADL_der values across CCHS cycles
# adl_fun() is specified in variable_details.csv along with the
# CCHS variables and cycles included.
# To transform ADL_der, use rec_with_table() for each CCHS cycle
# and specify ADL_der, along with the various ADL variables.
# Then by using merge_rec_data() you can combine ADL_der across cycles.
