Question

analyzing impact of family history on depression
a recent study found that disorders, such as depression, can run in the same family. what valuable insight about mood disorders can be inferred from these results?
○ health professionals should exclude family history when diagnosing mood disorders.
○ both family history and external factors can trigger the onset of depression and bipolar disorder.
○ children are unlikely to receive a mood disorder diagnosis if their parents were previously diagnosed.
○ when looking at a family tree, mood disorders rarely appear across several ancestral lineages.

Explanation:

• Option 1: The study shows family history is relevant for mood disorders, so excluding it is wrong.
• Option 2: Since disorders run in families (genetic/family history aspect) and external factors also contribute to mood disorders like depression, this is a valid inference.
• Option 3: If disorders run in families, children with diagnosed parents are more likely, not less, to be diagnosed.
• Option 4: The study says disorders run in families, so they should appear across lineages, not rarely.

Answer:

B. Both family history and external factors can trigger the onset of depression and bipolar disorder.
