Partial Hospitalization, also known as "PHP" or Day Treatment, is a type 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 various treatment activities and techniques during the day and then returns home in the evening. This takes place anywhere from five to seven days a week, depending on the severity of the problem. Partial Hospitalization can be beneficial for addicted persons who cannot afford long-term inpatient care, or who are unable to be away from their families for prolonged periods of time. While in Day Treatment, clients participate in typical counseling and therapy for addiction issues while also addressing mental health issues which could prevent them from making progress and obtaining gains throughout the treatment process.
