___________ measures the number of different food groups consumed over a specific reference period (24 hr / 48 hr / 7 days).
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Household Dietary Diversity Scale
The Household Dietary Diversity Score/Scale (HDDS) counts how many different food groups a household consumed over a fixed recall period of 24 hours, 48 hours or 7 days, and is used as a proxy for diet quality and nutritional access.
The Household Food Insecurity Access Scale records anxiety and inadequate access to food, the Household Hunger Scale captures the severest hunger experiences, and the Coping Strategy Index/Scale records the behaviours a household adopts when food runs short — none of them counts food groups.
