Dear all,

I'm a doctoral student currently working on a research project in which I would like to investigate to what degree variation in biomarker measurements is depending on interviewers. Therefore, I had planned to work with the interviewer IDs, but got confused on how to read them. Any help on the following three questions/observations would be greatly appreciated.

1. Were field teams assigned randomly to households within primary sampling units?

2. In the project report I have read that in total 789 field teams were deployed to conduct all interviews/measurements. Paragraph 1.7 states that each field team consisted of 1 supervisor, 3 female interviewers, 1 male interviewer and 2 health investigators. In total, this would mean that 789*4=3156 interviewers and 2*789=1578 health investigators were involved. However, the variable hv018 (=interviewer ID) only contains 523 unique values, so I would assume that this is actually the field team ID. But since 523 is not equal to 789 I'm very confused about the interviewer ID. What does it actually depict?

3. Who took blood pressure measurements? The health investigators or the interviewers? I saw that it is documented which health investigator took the blood sample for HIV testing, but couldn't find the same info for blood pressure. Is there even any way to tell who took the blood pressure measurements (this is what I'm mainly working with)?

Thanks a lot in advance for any help with this.

Best regards,
Richard
