Hi all,

I am looking into how and why ratings or attitudes towards a hypothetical construct or subject (ie, something that persons do not know) can differ over time. More specifically, in our study we asked participants to give their attitudes towards a hypothetical construct (ie, potential medication) at two points in time.

For those, where the attitudes differed (ie, they rated the same hypothecial medication differently at the two points in time): I am wondering whether their attitude changed over time (which was max. 3 weeks) if we simply found measurement error. Are there any explanations on the fluidity of attitudes towards hypothetical constructs? So far, I have not been able to find literature on this. If you have suggestions on literature of keywords to narrow my search, I would much appreciate it.

Another explanation would be that differences in context account for the differences in attitudes/ratings. Our two study time points were in different settings (at the hospital and at home). This is sub-opitmal methodology, but are there any sources that show differences in ratings depending on the context/situation?

Thank you for your help!
