Multivariable Adjusted Mean Differences in Ratings of Participants by Adult Child Study Partners (SPs) And Other SPs as Compared to Spousal SPs.
| Characteristic | Adult Child SP | Other SP |
|---|---|---|
| Mean Difference (95%CI) | Mean Difference (95%CI) | |
| Activity levela | 0.0(−0.08–0.09) | 0.01(−0.10 to 0.08) |
| Current memoryb | −0.20(−0.38–−0.03)* | −0.09(−0.27 to 0.09) |
| Judgmentc | −0.16(−0.33–0.01) | −0.11(−0.30 to 0.07) |
| Organizationd | −0.18(−0.35–−0.02)* | −0.06(−0.24 to 0.11) |
| BDRSe | −0.10(−0.52–0.32) | −0.06(−0.39 to 0.51) |
Note. SP = study partner. 95%CI = 95% confidence interval. Spousal SPs are reference group. Multivariable models were built using forward stepwise regression with alpha-to-keep of 0.15. All models statistically control for cognition as measured by the Mini-Mental Status Exam (MMSE), Trails B, and number of impairments in instrumental activities of daily living (IADLs). Models of activity level and organization also control for Trails A and number of impairments in basic activities of daily living (BADLs). Model of BDRS also controls for Serial 7s, Boston Naming, Animal Fluency, and BADLs.
Activity level = Average of ratings on 10 items. Higher scores reflect more activity.
Current memory = Single item ranking from 1 to 5. Higher scores reflect worse memory.
Judgment = Single item ranking from 1 to 5. Higher scores represent poorer judgment.
Organization = Single item ranking from 1 to 5. Higher scores represent worse organization.
BDRS = Blessed Dementia Ratings Scale is a 22-item measure 2-year change in participant’s cognition.
