The research conducted in this article was a combination of both a longitudinal study and cross sectional study. It is a longitudinal study as the same group was tested from January 2013 and then again in December 2014.

However, many patients do not adhere to the prescribed treatment, resulting in a multitude of problems including recurrence of symptoms and hospitalization (MacEwan et al., 2016). Adherence therapy is a form of psychotherapy in which patients discuss their feelings about their mental illness, treatment, and life (Chein et al, 2016). Adherence therapy is an effective addition to the medical treatment of schizophrenia because it results in improved outcomes for patients.…
