Final answer:
An internal barrier to seeking help for mental health is mistrust of the health care system, which is influenced by past exploitation and discrimination, and requires culturally sensitive solutions to be addressed.
Step-by-step explanation:
An example of an internal barrier to seeking help for mental health is mistrust of the health care system. This barrier is psychological and revolves around apprehension or skepticism regarding the intentions and practices within the healthcare industry. This sentiment has been found particularly prevalent among certain ethnic minorities due to historical episodes of medical exploitation, such as the Tuskegee Experiment, and ongoing discrimination. As such, mistrust acts as an impediment to the pursuit of mental health services, even when such services are available and financially accessible. Efforts to improve trust in the healthcare system might involve community outreach, patient education, and the inclusion of culturally sensitive practices within healthcare settings.
