Search Existing Data Requests

The Knight ADRC has supported many investigators at Washington University and at other institutions over the years. We wish to avoid the situation where two investigators study the same research question to avoid duplication of effort and potential conflict. To determine if your topic has already been studied with our resources, please search our database. If you find that your topic or a related topic has been submitted, you may wish to contact the investigator to inquire about their findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID number (e.g. T1004), the full request has been submitted and is either approved, disapproved or in process. If an entry has no ID number, then it represents a submission that has not yet been reviewed. Search terms are applied across an entire requests application including variables not displayed below. A more specific, detailed search may yield better results depending upon your needs.

Project Title: Personality Predictors of Dementia Onset and Progression: An Integrated Data Analysis

Date: December 21, 2021 at 5:17 pm

Request ID: D2011

Aim 1: Examine whether baseline personality and indicators of psychological well-being (Positive Affect, Negative Affect) prospectively predict dementia onset.

Aim 2: Examine whether baseline personality and indicators of psychological well-being (Positive Affect, Negative Affect) prospectively disease progression (i.e. cognitive decline) following dementia diagnosis.

Aim 3: Use an integrated data analytic framework to investigate overall and sample-specific personality predictors of dementia onset and progression in six longitudinal studies.
