Associations Between SCARED^a Scale Score Over 0 and Mental Health Outcomes Among Health Care Proxies of Nursing Home Residents with Advanced Dementia

	SCARED = 0 n (%) or Mean (SD) Value	SCARED > 0 n (%) or Mean (SD) Value	Unadjustedb Parameter Estimate (95% CI)	Adjustedb,c Parameter Estimate (95% CI)
Depression (CIDI-SF)d	19/393 (4.8%)	30/273 (11.0%)	2.43 (1.34, 4.41)	2.59 (1.14, 5.85)
Psychological Distress (K6)e	253/459 (55.1%)	237/311 (76.2%)	2.61 (1.89, 3.59)	2.31 (1.55, 3.43)

^aStressful Caregiving Adult Reactions to Experiences of Dying (SCARED) scale, dichotomized as 0 vs. > 0; higher scores indicate greater distress.

^bDepression and psychological distress outcomes modeled with logistic regression, parameter estimate is odds ratio. General Mental Health outcome modeled with linear regression, parameter estimate is beta coefficient.

^cAdjusted for: health care proxy age, sex, education (college or greater vs. less), relationship to resident (spouse vs. other), baseline antidepressant use, hours visiting resident per week (≥ 4 vs. < 4), current antidepressant use, baseline depression (CIDI-SF outcome only), prior assessment K6 score (K6 outcome only), prior assessment SF-12 score (SF-12 outcome only), resident age, resident comfort (Symptom Management at End-Of-Life in Dementia scale) (CIDI-SF outcome only), and adjusted for clustering due to repeated measurements.

^dShort Form Composite International Diagnostic Interview (CIDI-SF), n=610.

^eK6, (range 0–24), higher scores indicating greater distress, dichotomized 0 vs. > 0, n=769.

^fSF-12 mental health subscale, higher scores indicate better mental health, n=772.
