A social worker acts as a client advocate, educator, coordinator of care, and an adviser. He or she will work as a liaison with the family, and will look at helping with finances, admissions, discharges, housing, follow-up appointments to outside services, and is sometimes the link to the courts and any legal procedures.
A psychologist works with individuals, couples, and families by identifying and diagnosing mental behavioural and emotional disorders. He or she will then develop a treatment plan, and if necessary, collaborate with doctors or social workers to help the patient carry through with the desired changes. In a nutshell, a social worker addresses problems within our society. A psychologist addresses problems due to our society.
