Outcome Results at 4 Months Postrandomization, Based on General Linear Modeling^a

Outcome results	COPE group least squares mean (95% CI) (n = 129)	Usual care group least squares mean (95% CI) (n = 123)	p-value
Outcomes for persons living with ADRD
Functional independence	2.8 (2.7, 3.0)	2.8 (2.6, 2.9)	.61
Activity engagement	2.1 (2.0, 2.2)	2.1 (2.0, 2.1)	.30
Behavioral and psychological symptoms score	9.7 (5.2, 14.2)	12.7 (8.3, 17.1)	.07
Outcomes for caregivers
Perceived well-being	3.2 (3.1, 3.3)	3.0 (2.9, 3.0)	<.001
Confidence using activities	8.2 (7.7, 8.8)	7.9 (7.4, 8.4)	.12
Distress level due to 14 behavioral and psychological symptoms of persons living with ADRD	4.7 (2.1, 7.3)	6.4 (3.9, 9.0)	.13

Notes: ADRD = Alzheimer’s disease and related dementia; CI = confidence interval; COPE = Care of Persons with Dementia in their Environments.

^aCovariates for all outcome models except the model for self-reported quality of life of persons living with ADRD included baseline values of: corresponding outcome; caregiver gender, race, ethnicity, education, relationship to person living with ADRD, depressive symptoms, living arrangement, baseline hours/week supervising person living with ADRD, and Saint Louis University Mental Status (SLUMS) score of person living with ADRD. Covariates for the self-reported quality of life of persons living with ADRD model: baseline value of self-reported quality of life; person living with ADRD age, gender, race, ethnicity, education, relationship to caregiver, living arrangement, and SLUMS score. For all outcomes, initial models included all covariates simultaneously, and final models included statistically significant covariates in initial models.
