The largest mental health therapy specialties

Mental health is vitally important to our well-being. According to the CDC, one in five adults in the U.S. experience at least one mental health condition every year. And it’s estimated that nearly 10 million people a year experience a mental illness or condition that interferes with or impacts major life activities.  

This area of healthcare is undergoing significant change. As the stigma surrounding mental health care gradually diminishes and technology makes getting help more accessible, demand for more mental health specialists will grow.  

Below, we rank the 10 largest mental health therapy specialties.

Licensed clinical social work likely tops the list because it is potentially more accessible than other types of professions on our list. Depending on the state, earning a master’s degree in social work could take between 1-3 years. Becoming a psychiatrist or clinical psychologist could possibly take between 8-13 years.  

The demand for social workers is also on the rise. According to the Bureau of Labor Statistics, employment is “projected to grow 12% from 2020 to 2030, faster than the average for all occupations.”

Psychologist vs. Psychiatrist: what’s the difference? 

In casual conversation, people often use “psychiatry” and “psychology” interchangeably. This is an easy mistake to make, as there are similarities between the two specialties.  

Both psychologists and psychiatrists are trained to identify mental issues and disorders and can treat these conditions using talking therapies. Under the surface, however, the specialties have different educational requirements, different credentials and different treatment approaches.  

In general, it can be easy to differentiate the two specialties by remembering that psychiatrists are medical doctors while psychologists are not. Psychologists also cannot prescribe medication to treat mental health conditions.
