Outpatient treatment gives treatment clients the ability to maintain specific obligations and elements of their life-style while getting involved in alcohol and drug rehabilitation services. Outpatient treatment is a moderate amount of treatment, and should not be mistaken for the amount of rehabilitation provided in an inpatient or residential rehabilitation setting which can be a lot more intensive. Outpatient treatment might be suitable for a person who has a short history of substance abuse for example, but will almost certainly not be adequate for someone whose rehabilitation needs exceed that which outpatient treatment is prepared to provide. Individuals involved in substance abuse often require a considerable environmental change, because many of the things that prompt their drug and alcohol use are strictly environmental. For example, if someone has been physically or psychologically abused and this is triggering their substance abuse, there is no way for any treatment efforts to achieve success should they return to such situations each day. In outpatient treatment, individuals can benefit from group and one-on-one therapy, in addition to family therapy services. In outpatient treatment, most facilities offer services six or seven days per week on either a part-time or full-time basis for four weeks or longer in some cases.
