1. How does the diathesis-stress model explain the onset of mental disorders?

A. Stress alone is sufficient to cause mental disorders.
B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
C. Only genetic factors cause mental disorders.
D. Environmental stressors alone can cause mental disorders.

Correct answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.

2. When examining heredity, mental disorders are almost always ________

A. influenced by one particular gene.
B. influenced by multiple genes.
C. influenced by recessive genes.
D. not influenced by genes.

Correct answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

3. How do childhood experiences influence adult psychopathology?

A. Childhood experiences have no impact on adult psychopathology.
B. Childhood experiences can have a profound impact on adult psychopathology.
C. Childhood experiences are unrelated to adult psychopathology.
D. Childhood experiences have only a minimal impact on adult psychopathology.

Correct answer: B

Rationale: The correct answer is B. Childhood experiences, such as trauma and attachment issues, can indeed have a profound impact on adult psychopathology. These experiences can shape an individual's psychological development, influencing their mental health and well-being throughout their life. Choice A is incorrect as research shows that childhood experiences do play a significant role in adult psychopathology. Choice C is also incorrect as there is evidence supporting the link between childhood experiences and adult psychopathology. Choice D is incorrect because childhood experiences can have more than just a minimal impact on adult psychopathology; they can be quite substantial.

4. How does the biopsychosocial model differ from the biomedical model?

A. The biopsychosocial model focuses solely on the biological aspects of disease.
B. The biopsychosocial model includes biological, psychological, and social factors, whereas the biomedical model focuses on only biological factors.
C. The biopsychosocial model is outdated and has been replaced by the biomedical model.
D. The biopsychosocial model is identical to the biomedical model.

Correct answer: B

Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.

5. How is binge-eating disorder different from bulimia?

A. Typically eat much smaller portions before purging the food.
B. Do not typically purge the food they eat.
C. Only purge their food after several binge sessions.
D. Often resort to anorexic methods to rid themselves of the food they have eaten.

Correct answer: B

Rationale: The correct answer is B because individuals with binge-eating disorder do not typically engage in purging behavior, unlike those with bulimia. Choice A is incorrect as individuals with binge-eating disorder do not purge the food they eat, so they do not eat smaller portions before doing so. Choice C is incorrect as they do not purge their food after several binge sessions. Choice D is incorrect as individuals with binge-eating disorder do not resort to anorexic methods to rid themselves of the food they have eaten.
