Notes: CG = caregiver; NPI-Q = Neuropsychiatric Inventory-Questionnaire, PGDRS = Psychogeriatric Dependency Rating Scale, MMSE = Mini-Mental State Examination.

^aAll significant univariate variables entered using stepwise methods. Patient age, MMSE, Number of other people available to assist PWD, number of unmet safety needs, CG age, CG caring for another dependent, CG skills counseling unmet need, CG emotional support unmet need, CG mental health counseling/psychiatric care unmet need, and CG primary medical care unmet need did not meet the model inclusion parameters.

^bAll significant univariate demographic and context variables entered into Block 1. Significant hypothesis-driven predictor variables entered using stepwise methods into Block 2. MMSE, number of unmet safety needs, CG skills counseling unmet need, CG emotional support unmet need, CG mental health counseling/psychiatric care unmet need, and CG primary medical care unmet need did not meet the model inclusion parameters into Block 2.
