Late life cognitive activity is a composite measure of frequency of participation in 7 cognitively stimulating activities during the past year. Activities include reading, writing letters, visiting a library, and playing games such as chess or checkers. These items involve information processing or retention and have relatively few barriers to participation.
Participants are asked to rate each item on a 5-point scale. Values for items 2-7 are flipped so that higher values indicate more frequent participation (see table below). The variable ranges from 1 to 5 and is calculated by averaging the individual item scores.
Participants are asked the following questions:
Response choices for each item:
|Value||Item 1||Items 2-7 (flipped)|
|1||None||Once a year|
|2||Less than one hour||Several times a year|
|3||One to less than two hours||Several times a month|
|4||Two to less than three hours||Several times a week|
|5||Three or more hours||Every day/almost every day|
Note: At baseline interview, item #2 reads, “In the last ten years, how often did you visit a library?”
The variable is calculated if at least half of the items are non-missing.
The baseline version of this variable is available upon request.
