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 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 seriousness of the problem. Partial Hospitalization can be beneficial 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 take part in standard counseling and therapy for addiction issues while also addressing mental health troubles which could prevent them from staying sober once treatment is complete.
