Abbreviations: CMAI, Cohen-Mansfield Agitation Inventory; ARBS, Agitated and Reactive Behavior Scale; SE, standard error; MIE, marginal interaction effect – the marginal interaction of follow-up by intervention effect

Fixed effect covariates: age, sex, race, activities of daily living score, cognitive function score, psychotic disorder, bipolar disease, depression, anxiety, dementia, anti-depressant use, anti-anxietal use, antipsychotic use, nursing home corporation, time from MDS collection to CMAI score*, baseline ARBS*, baseline CMAI†, indicator of baseline/follow-up score, treatment group, interaction of baseline/follow-up measure and treatment group

Random effects: random intercept for nursing home, random intercept for the interaction of baseline/follow-up measure and nursing home, random intercept for data collector*, random intercept for individual *exclusive to CMAI model, †exclusive to ARBS and ARBS-CMAI model
