This variable is only available in MAP, MARS, and LATC.
Cognitive resources at age 40 measures the presence of materials that support cognitive activity (e.g., encyclopedia, library card, magazine subscriptions) in the home at the age of 40. The variable is measured using an 8-item scale issued at baseline.
Participants are asked to indicate whether they had each of seven items available (questions 1-7) and to estimate the number of books in the home (question 8). Responses for question 8 are adjusted to range from 0 to 1. The overall score of cognitive resources at age 40 ranges from 0 to 8 and represents the sum of the 8 questions. Higher scores indicate greater access to materials.
Participants are asked the following questions:
