reliability and validity of the SRVersion.Methods:TheHABC-Monitor has three patient symptom domains (cognitive, functional, and behavioral/psychological) with parallel items for both the CG Version and the SRVersion. The Caregiver Quality of Life domain is included on the CGVersion but not the SRVersion. Patients (n1⁄4 291) were consecutively approached and consented during a patient’s routine visit to their primary care provider. The SR Version was administered to each patient during a subsequent phone interview. Results: The HABC-Monitor demonstrated excellent fit for the confirmatory factor analysis model (RMSEA 1⁄4 0.020, CFI 1⁄4 0.974, WRMR 1⁄4 0.837); good internal consistency (0.78-0.92); and adequate knowngroups validity, indicated by significant separation of TICSm severity groups.Conclusions:The SRVersion demonstrates good reliability and validity as a clinically practical multidimensional tool for measuring symptoms of dementia. The tool can be used with the CG Version to provide useful feedback (via monitoring of symptoms) for modifying care plans for dementia patients and their informal caregivers.
