Outpatient treatment gives rehab clients the opportunity to maintain specific obligations and elements of their lifestyle while taking part in alcohol and drug treatment services. Outpatient treatment is a moderate degree of rehabilitation, and should not be mistaken for the amount of treatment offered in an inpatient or residential rehabilitation program that is significantly more intensive. Outpatient treatment might be suited to someone who has a brief history of drug or alcohol use for example, but will most surely not be sufficient for an individual whose rehabilitation needs go beyond what outpatient treatment is able to offer. Individuals involved in drug and alcohol use often need an extreme change of environment, because many of the things that trigger their drug and alcohol use are purely environmental. By way of example, if someone is being physically or psychologically mistreated and this is triggering their drug or alcohol use, it's impossible for any rehabilitation efforts to have success whenever they return to such circumstances on a regular basis. In outpatient treatment, individuals can engage in group and one-on-one therapy, as well as family therapy services. In outpatient treatment, most programs will provide services six or seven days per week on either a part-time or full time schedule for four weeks or longer in some cases.
