MAP, MARS, LATC
This variable is only available in MAP, MARS, and LATC.
Childhood cognitive activity is an 11-item composite measure of frequency of participation in cognitively stimulating activities, issued at baseline. Participants are asked how often they engaged in cognitively simulating activities at age 6 (3 items) and at age 12 (8 items).
Participants are asked to rate the items on a 5-point scale. Values for questions #1-3 and 5-10 are flipped so that higher values indicate more frequent participation across all items (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 question:
|Value||Items 1-3, 5-10 (flipped)||Items 4, 11|
|1||Once a year or less||None|
|2||Several times a year||Less than one hour|
|3||Several times a month||One to less than two hours|
|4||Several times a week||Two to less than three hours|
|5||Every day/almost every day||Three or more hours|
Note: The variable is calculated if at least half of the items are non-missing.
