From a Torah perspective, the role of the psychologist is to bring the patient to a state where they can be mekayem taryag mitzvos. This includes ivdu es Hashem be’simchah, the mitzva of kibbud av ve’em, taharas ha’mishpacha and the mitzva of limmud torah.
If one of these needs to be broken as a stop-gap measure, it needs to be fixed in the long run.
So the therapists job is not finished till he has tidied up after himself.
