Partial Hospitalization, also known as "PHP" or Day Treatment, is a type of rehabilitation program which works to treat substance abuse problems and mental health conditions which may be co-occurring. In a PHP program, the person in treatment takes part 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 seriousness 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 take part in typical counseling and therapy for addiction issues while also addressing mental health problems which could prevent them from making progress and obtaining gains throughout the treatment process.
