Individual therapy is a joint process between a therapist and a person in therapy. Common goals of therapy can be to inspire change or improve quality of life. Family therapy is a type of psychotherapy that involves all members of a nuclear family or stepfamily and, in some cases, members of the extended family (e.g., grandparents). A therapist or team of therapists conducts multiple sessions to help families deal with important issues that may interfere with the functioning of the family and the home environment.
