The primary distinction between psychiatrists and psychologists lies in the medical and biological interventions that psychiatrists are trained to provide. Psychiatrists are licensed medical doctors who can prescribe medication and utilize medical treatments to address mental health disorders, which involves an understanding of the biological underpinnings of mental health conditions. This medical training allows them to assess both the psychological and physiological factors that contribute to mental health issues.

In contrast, psychologists often focus more on therapeutic techniques and psychological assessments based on behavioral theories, cognitive processes, and empirical research methodologies, rather than medical interventions. While psychologists may employ various treatment strategies, their expertise typically does not include prescribing medication or managing medication-related side effects. This fundamental difference in training and approach is what sets psychiatrists apart in the field of mental health.
