  1. Can Judgment Predict Functioning in Assisted-Living? Elizabeth E. MacDougall, Ph.D. & William E .Mansbach, Ph.D. Hood College & MedOptions WHAT WE LEARNED • In a clinically-referred, assisted living sample: • NAB Judgment (NAB-JDG) scores displayed good internal consistency reliability. • NAB-JDG scores predicted basic and instrumental ADLs over and above a measure of general cognitive functioning (MMSE). • There were significant group differences on the NAB-JDG between participants with and without informed consent decisional capacity. RESULTS BACKGROUND • Neuropsychologists have called for better measures of judgment (Rabin et al., 2008). • The NAB-JDG (Stern & White, 2003) is an orally administered test that includes 10 practical judgment questions involving home safety and health/medical concerns. • There are no NAB-JDG data for dementia patients presented in the NAB manual. • Although the NAB-JDG is described in the manual as a test created with ecological validity in mind, there is no empirical evidence presented to support this claim. • Sample Demographics: • Median age – 84.5 • 71% female • 90% Caucasian • 65% widowed • 82% HS or more education • NAB-JDG scores ranged from 1 to 20 and were normally distributed: - Mean =13.48; standard deviation = 4.06. • Cronbach’s α based on standardized items =.82. 18 – 10 – 5 – 0 - Mean NAB Judgment Raw Score OBJECTIVES Yes No Did the participant have the capacity to consent? Error Bars: 95% CI Hierarchical multiple regression model with MMSE and NAB-JDG as predictors of PSMS To extend the initial work done by White and Stern (2003) on the reliability and validity of NAB-JDG scores and score inferences in an assisted-living sample with a high base rate of dementia. To contribute preliminary empirical evidence regarding the ecological validity of the NAB-JDG by examining the relation of the NAB-JDG with basic and instrumental ADLs. Hierarchical multiple regression model with MMSE and NAB-JDG as predictors of IADLs METHODS • 88 participants completed the NAB-JDG as part of a flexible battery of neuropsychological tests administered to assisted-living residents referred for evaluation of cognitive dysfunction. • Exclusion criteria: • <60 years old • <5 years of education • Any medical or psychiatric symptoms that would prevent the participant from completing the evaluation Note: R2 = .­11 for Step 1, ΔR2 = .08 for Step 2 (p < .01). *p < .01. Note: R2 = .­42 for Step 1, ΔR2 = .08 for Step 2 (p < .001). *p < .01, **p < .001. References: Rabin, L.A., Borgos, M.J., & Saykin, A.J. (2008).
