Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of drug rehabilitation facility which works to treat substance abuse problems and mental health disorders which may possibly be co-occurring. In a PHP facility, the person in treatment partakes in various treatment activities and methods in the day and then leaves in the evening. This is carried out several days a week, all dependent on the seriousness of the drug or alcohol problem. Partial Hospitalization can be helpful for drug or alcohol addicted individuals in Naperville who may not be able to afford long-term inpatient rehab, or who are unable to be apart from their home for extended lengths of time. While in Day Treatment, individuals take part in typical treatment services for addiction issues while also addressing psychological issues which could keep them from staying abstinent once treatment is done.
