Imagine that you are a psychologist working in private practice in the united states. you have a new client from a non-western culture who claims that her psychological problems are caused by evil spiritual forces emitted from her mother-in-law. would you consider this client delusional?

Yes, but only if this person is relatively educated and culturally integrated in the United States.
Delusion refers to a mental defect that make the victim believe something that is not considered as real by other people.
If the majority members of society generally believe in evil spiritual behavior, we can't really say this client is having a delusion.
