Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of rehabilitation program which works to treat substance abuse issues and mental health issues which may be co-occurring. In a PHP program, the individual in treatment participates in a variety of recovery activities and techniques during the day and then returns home in the evening. This is done anywhere from five to seven days a week, depending on the seriousness of the problem. Partial Hospitalization can be helpful for addicted persons who cannot afford long-term inpatient care, or who are unable to be away from their families for extended periods of time. While in Day Treatment, individuals participate in standard counseling and therapy for addiction issues while also addressing mental health troubles which could prevent them from staying sober once treatment is complete.
