MAP, MARS, LATC
This variable is only available in MAP, MARS, and LATC.
Middle adult age cognitive activity is assessed using a 9-item self-report scale issued at baseline. Participants are asked how often they engaged in cognitively stimulating activities at the age of 40 or from age 30 to 40. Items include reading, visiting a museum, attending theater/concert, visiting a library, reading newspapers, reading magazines, reading books, writing letters, and playing games.
Participants are asked to rate the items on a 5-point scale. Values for items 4-9 are flipped so that higher values reflect more frequent participation (see table below). The composite measure ranges from 1 to 5 and is the mean of the individual Item scores, with higher scores indicating greater cognitive activity.
Participants are asked the following questions:
Response choices for each item:
|Value||Item 1||Items 2-3||Items 4-9 (flipped)|
|1||None||Never||Once a year or less|
|2||Less than one hour||1-2 times||Several times a year|
|3||One to less than two hours||3-9 times||Several times a month|
|4||Two to less than three hours||10-19 times||Several times a week|
|5||Three or more hours||More than 20 times||Every day/almost every day|
Note: The variable is calculated if at least half of the items are non-missing.
