What is Health Psychology?
Public health psychology is a branch or subspecialty of health psychology. Public health psychologists focus on health at the population level as opposed to individual health. For example, public health psychology may target certain at-risk groups, such as low-income populations to prevent health problems.
The field of public health psychology involves the study of how psychological factors, social influences and certain thought processes can affect health. Researchers and doctors are continuing to discover that physical health can be influenced to some extent by psychological well-being.
Public health psychology takes an approach that combines psychological and behavioral factors, along with biological processes, such as genetics, to understand their role in illness and disease. Information and research are often presented to policy makers to improve and promote public health. The information, research and data that is collected is used to improve public health programs and policies, which helps individual patients.
What Does a Public Health Psychologist Do?
Public health psychologists investigate psychological factors and how they affect health concerns of populations. They use their knowledge of psychology to understand the connection between health issues and behavior and emotional factors. For example, a public health psychologist may research psychological factors that increase heart disease in lower income populations. Public health psychologists focus on the needs of a whole population or subpopulation as opposed to just an individual’s issues.
The duties of a public health psychologist may vary based on where they work. For example, some public health psychologists may focus on certain special populations, such as low-income pregnant women or disabled veterans. They may work to discover the health related psychological issues affecting that specific population.
They often target at risk populations, like smokers, and their work is related to other public health areas like nutrition, genetics and epidemiology. They often conduct scientific studies and collect information through a variety of methods including observation, surveys and interviews. Studies may be targeted at specific health issues such as substance abuse or teen pregnancy.
Regardless of the specific population they are focusing on, a large part of what a public health psychologist does is conduct, analyze, interpret and present their research studies. Public health psychologists may work as consultants for private and government industries and organizations, such as hospitals and rehabilitation facilities presenting the data they have collected.
Public health psychologists first identify the link between emotional well-being and physical illnesses. After the connection between behaviors, mental health and disease have been identified, public health psychologists may work with communities, hospitals and agencies to develop programs that promote mental well-being and disease prevention. For example, public health psychologists may develop and promote programs to improve eating habits for low-income individuals to decrease rates of type two diabetes.
Some public health psychologists use the data they research to work with lawmakers to develop laws and public policies that may promote disease prevention. For example, they may work with government agencies to try to address unfair practices in healthcare or influence public policies related to health issues. A small number of public health psychologists may also work in academia, teaching at colleges and universities.

Public health psychologists may work within the government or in private settings to lobby governmental agencies about issues such as inequalities in health care, or they may make recommendations to governmental agencies regarding health care reform.
