Lois was diagnosed with schizophrenia in college when she began to develop delusions that her roommate was following her all over campus and that all the teachers “wanted me to fail.” Her behavior became more erratic and disorganized, causing her to drop out of school. She was soon admitted to an inpatient unit for medical stabilization of her symptoms. Over the years, Lois has been inconsistent with her medications and has required at least two other hospitalizations. Her parents are concerned about her recent lack of structure secondary to quitting her job. They feel when she lacks structure, her symptoms begin to worsen.
