You normally used the '–ing' form of a participial adjective to describe a certain event that is the cause or reason of the feeling or reaction: an interesting research/account, for example. On the other hand, you use the
‘-ed’ form to describe the person with the feeling or reaction: I’m interested in the research, for example.
“The children gave a confusing account of what had happened.” is a better way to write it.
