Outpatient treatment gives rehabilitation clients the opportunity to maintain specific obligations and aspects of their way of life while getting involved in drug and alcohol rehab services. Outpatient treatment is a moderate degree of rehabilitation, and shouldn't be mistaken for the degree of rehab offered within an inpatient or residential treatment program which is significantly more intensive. Outpatient treatment may be suited to anyone who has a brief history of drug or alcohol use for example, but will certainly not be adequate for someone whose rehabilitation needs go beyond what outpatient treatment is able to provide. Individuals dealing with substance abuse often require an extreme change of environment, because many of the things that prompt their drug and alcohol use are purely environmental. For example, when someone is being physically or psychologically abused and this is prompting their drug or alcohol use, there is no way for any rehab efforts to achieve success if they go back to such circumstances each day. In outpatient treatment, clients can engage in group and individual therapy, as well as family therapy services. In outpatient treatment, most programs will provide services 6 or 7 days a week on either a part-time or full time schedule for four weeks or longer in some instances.
