My study group is 65 to 85 year olds. Through interviews I'm hoping to discover if financial issues and decision-making ever arise when discussing a life review. The literature suggests that they don't.
I don't do research in this area, but I am teaching Aging and Adulthood and having my students interview and write up life reviews. I could let you know anecdotally if this comes up. Obviously a class project is not a good data source, but it could give you an idea of whether it happens.
