incorporated into the Enhanced Face-to-Face Interview. The Leave-Behind  
Questionnaire administered in 2010 is called the Participant Lifestyle  
Questionnaire, and it includes questions on participation in general activities,  
relationships with others, and views on their life in general as well as  
specific aspects of their life.  
Physical Performance Measures and Biomarkers (Section I_R)  
Blood pressure  
Hearing test  
Breathing test (peak flow)  
Grip strength  
Balance tests (semi-tandem, side-by-side, and with [30/60] second full-  
tandem)  
Timed walk (8 ft., eligible if 65 or older)  
Height  
Weight (eligible if weight is under 300 pounds)  
Waist circumference  
Saliva (for which DNA was extracted and stored – eligible if saliva  
invalid previous wave or no saliva collection previous wave)  
Dry blood spots (analyzed for Hemoglobin A1c, total cholesterol and HDL  
cholesterol)  
With the exception of the timed walk, which was administered only to respondents  
65 years of age or older, the physical measures and biomarkers were conducted on  
the full enhanced face-to-face sample.  
Three separate consents were obtained to cover: 1) all of the physical measures,  
plus blood pressure; 2) saliva sample; and 3) dry blood spots. The physical  
measures booklet, which the interviewers used to administer the physical  
measures and biomarkers, is available on the HRS website Physical Measures  
2018. The booklet contains the consent forms, as well as instructions and  
protocols for all of the measurements.  
9G. Web  
In 2022, HRS administered its third wave of Web as an alternate mode for data  
collection for the core biennial interview. Web was offered as an alternative  
for telephone and regular face-to-face respondents only; respondents in the  
half-sample scheduled for the enhanced face-to-face interview were not eligible  
for Web this wave. Households previously selected as Web eligible 2018 remain  
Web eligible as long as they continue to meet eligibility criteria based on a  
prior report of internet access along with other selection criteria (e.g.,  
English speaking, self-respondent, non nursing-home resident in prior wave). In  
addition, the 2016 LBB new cohort households are also eligible for Web based on  
the same eligibility criteria.  
In total, 3,317 eligible households were identified. By design, 60% of eligible  
households were to be assigned to receive a web invitation, with the remainder  
receiving their usual mode of either telephone or face-to-face. This resulted in  
1,989 eligible households receiving the Web invitation and 1,328 eligible  
households not receiving the Web invitation. The intention was for this  
assignment to be random across cohorts and households. However, due to a  
programming error the designation was not random and should not be used to study  
mode effect in the 2022 wave.
