Lesson 11: Mental Disorders Part I
Compare and contrast the biomedical and biopsychosocial approaches to mental disorders.
The biomedical approach mainly focuses on the biological reasons for the disease.
The biopsychosocial approach considers the biology, but also includes psychological and cultural factors.
CRB If a medical researcher says "There are much higher rates of eating disorders in well-developed countries (like the USA) than in other countries" and are studying why, would this fit better in the biological or biopsychosocial approach? Explain why.
This is clearly the biopsychosocial approach. This researcher is clearly looking at the social and cultural factors these eating disorder patients face. This goes beyond the biological reasons for disease.
CRB True or false? One goal of the Biopsychosocial Approach is to use both direct therapies, which would act directly on the patient, and indirect therapy, which would increase social support for the patient, to treat Psychological Disorders.
True. One goal of the Biopsychosocial Approach is to use both direct therapies, which would act directly on the patient, and indirect therapy, which would increase social support for the patient, to treat Psychological Disorders.
