Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of rehabilitation program which works to treat substance abuse problems and mental health conditions 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 seriousness of the problem. Partial Hospitalization can be helpful for addicted individuals who may not be able to 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 standard 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.
