1. How does the biopsychosocial model differ from 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 Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach.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.

2. How does the diathesis-stress model explain the onset of 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.

3. Dr. Fox studies the causes of depression. In other words, she looks at factors that play a role in the ________ of depression.

Correct answer: A

Rationale: The correct answer is A, 'etiology.' Etiology specifically deals with the causes or origins of diseases like depression. Choice B, 'epidemiology,' focuses on the patterns, causes, and effects of health and disease conditions in defined populations. Choice C, 'prevalence,' refers to the proportion of a population found to have a condition. Choice D, 'resiliency,' relates to the ability to recover from or adjust to challenges.

4. What is the result when a single zygote separates into two parts, each developing into a separate individual?

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

5. Cross-cultural research on stress demonstrates that ________.

Correct answer: C

Rationale: Cross-cultural research on stress demonstrates that responses to stress vary cross-culturally. Choice A is incorrect because depression being a common response in all countries studied is not supported by cross-cultural research findings. Choice B is incorrect as it generalizes that stress rarely leads to illness in non-Western cultures, which is not universally true. Choice D is incorrect as culture-specific reactions can indeed respond to alterations in the environment, as observed in various cross-cultural studies.
