Partial Hospitalization, sometimes referred to as "PHP" or Day Treatment, is a type of drug and alcohol rehab program that works to deal with substance abuse issues and psychological problems which might be co-occurring. In a PHP center, the treatment client in treatment partakes in various rehabilitation services and techniques in the day and then leaves in the evening. This is done several days a week, depending on the seriousness of the drug or alcohol problem. Partial Hospitalization can be most effective for drug addicted people in Lykens who are unable to pay for long-term inpatient care, or for those who are unable to be apart from their households for extensive lengths of time. While in Day Treatment, individuals take part in typical counseling and therapy for alcohol or drug addiction problems while simultaneously overcoming mental health issues which could keep them from remaining abstinent after rehabilitation is done.
