Outpatient treatment gives treatment clients the chance to sustain certain obligations and elements of their way of life while taking part in drug and alcohol treatment services. Outpatient treatment is a moderate degree of treatment, and should not be mistaken for the degree of rehabilitation provided within an inpatient or residential rehab program which is significantly more intensive. Outpatient treatment may be ideal for somebody who has a short history of drug or alcohol use for instance, but will certainly not be sufficient for somebody whose rehabilitation needs go beyond what outpatient treatment is prepared to offer. Individuals involved in substance abuse often require a considerable change of environment, because many of the things that prompt their substance abuse are purely environmental. For instance, if someone else has been physically or psychologically abused and this is prompting their drug or alcohol use, there is no way for any treatment endeavours to succeed if they go back to such circumstances each day. In outpatient treatment, clients can take advantage of group and one-on-one therapy, as well as family therapy services. In outpatient treatment, most programs will provide services six or seven days each week on either a part-time or full-time basis for 1 month or longer in some cases.
