A psychologist is a specialist who is trained to study the science of mind and behavior in a scientifically-based manner and utilizes evidence to comprehend the way individuals think, feel, and behave. Psychologists are employed in a wide range of fields such as clinical practice, research, education, health, sports and organizations. They may be engaged in evaluating mental health, treating individuals, planning interventions, or carrying out research to develop the understanding of human behavior.
Psychiatrists do not always prescribe medication; this is because unlike them, psychologists do not usually prescribe medication, but rather concentrate on psychological therapeutic modalities, counseling, and behavioral approaches to help an individual achieve positive mental health and wellbeing. Recent studies focus on psychological interventions that are effective in treating depression, anxiety, and trauma, and research indicates that quality of life is improved permanently with psychological intervention administered by trained psychologists. In addition to mental health care, psychologists also help formulate policies, enhance education, and enhance healthy working environments. Their primary concern is the use of psychological science to ensure the more effective functioning and resilience of individuals (as well as communities).
