Are there significant differences, between countries, in the type of information used to inform decisions?
So you will have to find a way to aggregate, for each individual, how information was used across 4 scenarios.
For example, if you asked for a ranking, then "median rank of Information A [B, C, ..] across the 4 tasks" could
be used; or, if you asked for a score or a percentage "mean score (or percentage) across 4 tasks". You could then
compare these aggregated values between nationalities.
Their might be an issue with consistency - one participant perhaps uses information always the same way, another one
uses different information in different situations. Alternatively, a repeated measures approach or a multilevel model
could be useful. In a repeated-measures approach you could use "type of information" and "scenario" as repeated-measures
factors, and "nationality" as additional between-subjects factor.
Is there a correlation between the type of information social workers use to make decisions and how risk averse/interventionist they are (which intervention they choose?
Degree of risk aversion is an ordinal scaled dependent variable. If you have interval scaled values for information
utilization (such as "for person k, mean importance for informations A to E were 11, 22, 13, 32, 22"), you could
regress median degree of risk aversion on this (ordinal regression). If this means too much aggregation on both
sides of the equation, maybe a multilevel approach (generalized estimating eqiations GEE) could be considered.
With kind regards
