Is it as easy (or easy enough) to enroll participants in RCTs if you need their whole household, rather than just them, to consent to participate? Does it create any bias in the results?
I’d assume that 1. you don’t need the whole household, depending on the original sample size, it seems plausible to randomly select a subset of household members [1](e.g., in house A you interview recipient and son, in B. recipient and partner, etc...) and 2. they wouldn’t need to consent to participate, just to be surveyed, no?
If these assumptions didn’t hold, I’d be more worried that this would introduce nettlesome selection issues.
I recognise this isn’t necessarily simple as I make it out to be. I expect you’d need to be more careful with the timing of interviews to minimise the likelihood that certain household members are more likely to be missing (children at school, mother at the market, father in the fields, etc.).
