Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a kind of drug and alcohol rehabilitation program that is meant to treat drug and alcohol addiction problems and mental health problems which may possibly be co-occurring. In a PHP program, the individual in treatment participates in a variety of treatment activities and methods during the day and then returns home in the night time. This is carried out anywhere from five to seven days a week, all dependent on the severity of the drug or alcohol problem. Partial Hospitalization can be most effective for addicted persons in Newark who are unable to cover the costs of long-term inpatient rehab, or who are unable to be away from their families for extensive lengths of time. While in Day Treatment, people take part in standard treatment services for drug and alcohol addiction problems while at the same time addressing mental health problems which could keep them from staying abstinent once rehabilitation is complete.
