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 issues which may be co-occurring. In a PHP program, the person in treatment takes part in a variety of 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 individuals 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 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.
