Protocol - Cognitive Changes
Description
The informant (e.g., caregiver) is asked a series of questions to ascertain changes in the subjects cognition over the past two years. The informant indicates whether the subjects cognition in relation to various situations has improved, stayed the same, or gotten worse. These questions are from the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE).
Specific Instructions
The introduction refers to the last month or so of the subjects life. The questions can be administered to the informant before that time, perhaps when there is potential cognitive decline.

Protocol
Now we want you to remember what Rs FIRST NAME was like two years ago and to compare it with what [he/she] is like now. Two years ago was in {CURRENT INTERVIEW YEAR - 2}. I will read situations where Rs FIRST NAME has to use [his/her] memory or intelligence and we would like you to indicate whether this has improved, stayed the same, or gotten worse in that situation over the past two years.
Note the importance of comparing [his/her] present performance with two years ago. So if two years ago Rs FIRST NAME always forgot where [he/she] had left things, and [he/she] still does, then this would be considered "not much change."
Now we want you to remember what Rs FIRST NAME was like [when we interviewed [him/her] in Rs LAST INTERVIEW MONTH, YEAR /two years ago] and to compare it with what [he/she] was like toward the end of [his/her] life, but leaving out the last month or so of [his/her] life. I will read situations where Rs FIRST NAME had to use [his/her] memory or intelligence and we would like you to indicate whether this had improved, stayed the same, or gotten worse in that situation over that time period.
Note the importance of comparing [his/her] performance toward the end of [his/her] life with [when we interviewed [him/her] in Rs LAST INTERVIEW MONTH, YEAR/two years ago]. So if two years ago Rs FIRST NAME always forgot where [he/she] had left things, and [he/she] still did, then this would be considered "not much change."
1. Compared with two years ago, how is Rs FIRST NAME at:
Remembering things about family and friends, such as occupations, birthdays, and addresses.
Has this improved, not much changed, or gotten worse?
Compared with [when we interviewed [him/her] in Rs LAST IW MONTH, YEAR/two years ago], how was Rs FIRST NAME at:
Remembering things about family and friends, such as occupations, birthdays, and addresses.
Had this improved, not much changed, or gotten worse?

Personnel and Training Required
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "dont know" response is provided.
Equipment Needs
The PhenX Working Group acknowledges these questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.Requirements
| Requirement Category | Required |
|---|---|
| Major equipment | No |
| Specialized training | No |
| Specialized requirements for biospecimen collection | No |
| Average time of greater than 15 minutes in an unaffected individual | No |
Mode of Administration
Interviewer-administered questionnaire
Lifestage
Senior
Participants
65 years of age and older
Selection Rationale
The IQCODE is the most commonly used informant-based assessment of cognition.
