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 issues which may be co-occurring. In a PHP program, the person in treatment participates 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 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 extended periods of time. While in Day Treatment, clients take part in typical counseling and therapy for addiction issues while also addressing mental health troubles which could keep them from staying sober once treatment is complete.
