One of the goals of the Study on Global Ageing and Adult Health (SAGE) is to examine and measure the relationship between health and well-being. SAGE is the first study to measure and distinguish between two concepts of well-being: experiential and evaluative, in low and middle income countries. The short version WHO Quality of Life (WHOQOL) instrument was used to measure evaluative well-being. An adapted version of the Day Reconstruction Method (DRM) was used to measure emotional or experiential well-being.
However further substantiation for measuring emotional well-being and adjusting for systematic biases in self-report is required.
Objectives:
1. To compare short versus fullday version of the DRM questionnaire
2. Reproducibility of the questionnaire: test-retest
3. To compare self-report to biological markers of stress and negative emotions
Methods:
The short and fullday versions of the DRM questionnaires were implemented in Jodhpur, Rajasthan, India.
The target sample size was 1560 respondents, 200 respondents on Monday through Saturday and 360 respondents on Sunday.
The version of the short questionnaire was randomly assigned to each selected respondent:
short "morning" (Set A)
short "afternoon" (Set B)
short "evening" (Set C)
short "full day" (Set D).
Each set was assigned to 390 respondents.
The interviewer returned to the same household and respondent one or two weeks later on the same weekday or weekend day for a second interview. On this occasion the full day DRM questionnaire was administered. Interviewers were asked about the previous day (i.e. day prior to the interview) in each interview. Duration of the short version module of the DRM was at most 15 minutes of interview time in total.
Blood samples:
Blood samples were collected after the final interview by dry blood spot(DBS) and venepuncture (i.e. 2 blood samples per respondent - one DBS and one test tube). Protocols for the DBS and venepuncture followed procedures previously used for the SAGE pilot and full survey. The blood samples will be examined for fibrinogen, while also assessing the characteristics of DBS versus venepuncture.
Review of hospital records:
Each respondent was asked if the survey team would be allowed to review their hospital records. Two groups of subjects will be selected and their records reviewed:
1. positives: individuals with a previous diagnosis of any of the 8 conditions included in the fullday questionnaire: arthritis; angina; diabetes; chronic lung disease; asthma; depression; hypertension; cataracts.
2. negatives: matched individuals free of all 8 conditions.
This would allow us to determine the accuracy, reliability and predictive values of self-reported health conditions as part of this survey.
