Final answer:
Health psychology is not only concerned with psychological well-being; it examines the intersection of biological, psychological, and sociocultural factors to promote overall health.
Step-by-step explanation:
The statement that 'Health psychology is only concerned with psychological well-being' is false. Health psychology actually focuses on the intricate interplay among biological, psychological, and sociocultural factors, adhering to the biopsychosocial model. This field aims to improve health through research, education, policy, and interventions. Health psychologists might delve into the genetic and behavioral correlations to health, assess stress impacts on well-being, and design strategies to alter unhealthy behaviors. Ultimately, they work to pinpoint which population segments may be more vulnerable to adverse health outcomes based on psychological or behavioral factors.
