Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of alcohol and drug rehab facility which is meant to handle drug and alcohol addiction disorders and mental health issues which may possibly be co-occurring. In a PHP center, the treatment client in treatment participates in various treatment services and approaches during the day and then returns home in the evening time. This is carried out several days a week, depending on the seriousness of the problem. Partial Hospitalization can be most effective for drug addicted persons in Mission Viejo, California who may not be able to pay for long-term inpatient treatment, or who are unable to be apart from their home for extended lengths of time. While in Day Treatment, treatment clients participate in typical counseling and therapy for alcohol or drug addiction issues while simultaneously dealing with mental health issues which may deter them from remaining abstinent when rehabilitation is done.
