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 takes part in various treatment 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 severity of the problem. Partial Hospitalization can be helpful 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, clients take part in standard counseling and therapy for addiction issues while also addressing mental health issues which could keep them from making progress and obtaining gains throughout the treatment process.
