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.

Correct Answer: B

Rationale: The correct answer is B: 'sufficient cause; necessary cause.' A sufficient cause will inevitably produce the disorder, but it is not the only factor. In this case, having the gene for Parkinson's disease is a sufficient cause, meaning it alone can lead to the development of the disease. However, it is not a necessary cause because Parkinson's disease can still develop without the presence of this gene. Choices A, C, and D are incorrect because they do not accurately describe the relationship between the gene and the development of Parkinson's disease as depicted in the question.

Correct Answer: C

Rationale: The correct answer is 'Sufficient causes.' Sufficient causes are conditions that alone are enough to guarantee the occurrence of a disorder. Necessary causes refer to factors that must be present for the disorder to occur but are not enough on their own. Contributory causes increase the likelihood of a disorder but are not enough to cause it by themselves. Protective factors are conditions that reduce the likelihood of a disorder occurring.

Correct Answer: B

Rationale: The correct answer is B. Socioeconomic factors like income and education levels are key determinants of mental health. They influence access to resources such as healthcare, housing, and social support systems, which can impact an individual's mental well-being. Additionally, socioeconomic factors can contribute to stress levels and overall quality of life, which in turn affect mental health. Choice A is incorrect because socioeconomic factors do play a significant role in mental health outcomes. Choice C is incorrect as socioeconomic factors have a broad impact on mental health beyond extreme cases. Choice D is also incorrect as numerous studies have shown the clear impact of socioeconomic factors on mental health.

Correct Answer: B

Rationale: The diathesis-stress model suggests that both genetic predisposition and environmental stress are necessary for the development of mental disorders, highlighting the interaction between nature and nurture. Choice A is incorrect because the model emphasizes the combined influence of genetic vulnerability and environmental stressors. Choice C is incorrect as the diathesis-stress model remains a valuable framework in understanding mental health. Choice D is incorrect because the model considers both genetic and environmental factors, not solely environmental factors.
