For adults aged 18 and older, ADDAYA indicates if and how much the respondent's health now limits moderate activities such as moving a table, pushing a vacuum cleaner, bowling, or playing golf.
This variable is one of 12 variables that use the Veteran's RAND 12-item (VR-12) measure of health status on the Adult Self-Administered Questionnaire (SAQ), a mail-back survey administered to all adults aged 18 and older in rounds 2 and 4 of MEPS data collection. The VR-12 replaced the Short-Form 12 Version 2 measure of health status on the SAQ in 2017.
The SAQ was first administered in 2000 and consists of two to three different measures of health status in each year. From 2000-2002, one of the measures used was Version 1 of the Short-Form 12 (SF-12®), until it switched to the Short-Form 12 Version 2 (SF-12v2 ®) in 2003, which it used until 2016. Beginning in 2017 (for both panels), The Veteran's RAND 12-item (VR-12) took the place of the SF-12v2 ®. The content of the 12 questions remained the same across the different versions, but the response scales of ADPALS, ADPWLM, ADMALS, and ADMWLM changed when the VR-12 was implemented in 2017. Please refer to the comparability sections of these variables for more information.
The VR-12 asks 12 questions to measure health related quality of life:
- General health today (HEALTH)
- Extent of limitations in moderate activities during a typical day (ADDAYA)
- Extent of limitations in climbing several flights of stairs during a typical day (ADCLIM)
