Outpatient treatment gives rehabilitation clients the ability to sustain certain obligations and aspects of their lifestyle while getting involved in drug and alcohol treatment services. Outpatient treatment is a moderate degree of rehab, and should not be mistaken for the degree of rehab offered in an inpatient or residential rehabilitation program which is much more extensive. Outpatient treatment may be ideal for someone who has a brief history of substance abuse as an example, but will almost certainly not be sufficient for a person whose rehabilitation needs go beyond what outpatient treatment is able to provide. Individuals involved in substance abuse often need a considerable environmental change, because most of the things that prompt their substance abuse are strictly environmental. For example, if someone is being physically or psychologically mistreated and this is prompting their substance abuse, it's impossible for any rehabilitation efforts to achieve success if they go back to such conditions each day. In outpatient treatment, clients can engage in group and individual therapy, as well as family counseling services. In outpatient treatment, most programs offer services five to seven days each week on either a part time or full time basis for thirty days or longer in some cases.
