Biological Psychologist or Psychiatrist

Biological psychology or psychiatry strives to understand the biological basis for mental disorders, including Alzheimer’s, bipolar disorder, schizophrenia, and others.

Military (Veteran) Psychologist or Psychiatrist

Individuals who serve in the armed forces are not exempt from mental health disorders. In fact, because of the demands of the military, being away from family, and the trauma of war zones, psychologists and psychiatrists are an essential part of military healthcare. Mental healthcare for soldiers doesn’t end when they are discharged, which is why the Veteran’s Administration employs psychologists and psychiatrists as well. Job duties of military psychologist and psychiatrist include:

  • Administering personality tests to new recruits
  • Evaluating mental health of active-duty soldiers
  • Diagnosing mental health disorders

Active duty psychologists and psychiatrists earn their degree prior to joining the service. Students may apply for the Health Professions Scholarship Program (HPSP) to cover the cost of a psychology doctorate or a medical degree in psychiatry. The professional association for military psychologists is the Society for Military Psychology and the one for military psychiatrists is the Society of Uniformed Services Psychiatrists (SUSP).
