Data Collection Event

CogUSA - Wave 3
Information collected in the wave 3 telephone survey primarily replicated the information collected in wave 1. It included confirmation of the respondent’s marital status and residence type, an update of health status and a replication of the cognitive measures administered in wave 1. The cognitive measures included the HRS episodic memory and mental status questions, numeracy, and a few brief measures designed to assess fluid reasoning, including a telephone adaptive version of the Woodcock-Johnson III number series test, and WJ-III retrieval fluency.
