I want to assess the health status of elderly people using a questionnaire, should I do home visit (in their own homes), or I can get them from primary health cares (or geriatric homes) during their visit. Which one is more accurate?
It has been a long time since last checked but NIA should have resources for human biopsies and autopsies. Please check their site. Somebody else may have a link for that.
If you already have a sample population, due to covid pandemic i believe home visit is better and the chance of loosing samples due to missing the visit time is less but if haven't yet choose your sample population, the cohort sampling method is better. I used cohort method in my thesis that was related to healthy elderly and in the end statically it presented the city population
I take population from 4 routs according the population of each
1. Geriatric homes (34)
2. From retirement associations (345)
3. Advertisement (253)
4. Public health centers (only those who had no disease) (179)
It depends on what you are looking for. Identify your variables. I agree home visit might be your first option.
