Answer: True
Explanation: Researchers and practitioners have stressed that cultural and minority groups should not be excluded in the fields of counseling and clinical psychology. To strive for culturally competent services, consideration should be given to individuals outside the mainstream subject groups when studying causes and treatments of diseases.
For example when researching the causes of a disease and the subjects are mainly white and male, the same causes may not apply to black male patients. Also, treatment may be more effective when it is given by a practitioner who shares the same cultural views as the patient.
