Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of drug and alcohol rehab program which works to deal with drug addiction issues and psychological disorders which may possibly be co-occurring. In a PHP center, the treatment client in treatment takes part in a number of treatment services and techniques during the day and then returns home in the evening. This is done several days per week, all dependent on the seriousness of the drug or alcohol problem. Partial Hospitalization can be most effective for addicted individuals in California who are unable to afford long-term inpatient care, or for those who are not able to be away from their families for extensive periods of time. While in Day Treatment, people participate in traditional counseling and therapy for addiction problems while also overcoming mental health disorders which could keep them from staying abstinent after treatment is complete.
