Programs known as Partial Hospitalization or Day Treatment centers are offered to certain people in Chappaqua who are having difficulties with co-occurring alcohol and drug abuse and mental health issues. These types of facilities may be beneficial to specific treatment clients in Chappaqua who may not be able to afford inpatient treatment, or who are unable to take part in an inpatient facility due to familial responsibilities. Partial hospitalization programs treat the client in the daytime through therapy and other rehabilitation strategies, and the individual goes home in the PM. Treatment is carried out anywhere from five to seven days per week on a tailored program which seeks to fully rehabilitate the person both physically and mind.
