Mood disorder after one year is __________ that expected in the general population

• A. Half
• B. Twice
• C. Three times
• D. Same

Answer: (B)

The main idea is comparing how common mood disorders are in this group after a year versus in the general population, i.e., the relative risk at one year. The best choice reflects that mood disorders persist at about twice the rate seen in general population after a year. So, if the general population has mood disorders at around 10%, this group would be roughly 20%. This twofold increase fits data from longitudinal studies showing ongoing psychosocial and biological factors that keep mood problems elevated beyond the acute phase.

The other options don’t fit the typical pattern: half would underestimate the increased risk, three times would imply a much larger jump than is usually observed, and being the same would indicate no difference, which contradicts the observed elevation in risk.
