Outpatient treatment gives rehabilitation clients the opportunity to sustain specific responsibilities and aspects of their life-style while taking part in drug and alcohol 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 treatment program which is much more intensive. Outpatient treatment may be suited to someone who has a brief history of substance abuse for example, but will most surely not be sufficient for someone whose rehab needs go beyond what outpatient treatment is prepared to provide. Individuals dealing with drug and alcohol use often need an extreme environmental change, because many of the things that prompt their substance abuse are purely environmental. For instance, when someone is being physically or psychologically mistreated and this is prompting their substance abuse, it's impossible for any treatment efforts to have success whenever they return to such conditions every day. In outpatient treatment, individuals can engage in group and individual therapy, along with family therapy services. In outpatient treatment, most facilities will provide services five to seven days each week on either a part time or full time basis for four weeks or longer in some instances.
