Positive depressive symptoms = presence of depressed affect and anhedonia (binary); “Compared to others your age, how would you rate your memory?” scale from 1 to 5, higher scores indicate poorer memory ratings; “Compared to 5 years ago how would you rate yourself today on memory?” scale from 1 to 5, higher scores indicate greater perceived decline; Neuroticism = average of ratings of applicability of 4 adjectives (moody, worried, nervous, calm [reverse coded]) scale from 1 to 4; higher ratings indicate adjectives described an individual better; Self-rated health = “How would you rate your health these days?”, scale from 0 to 10, higher scores indicate better self-rated health; Episodic memory = z-score of word recall activity on Brief Test of Adult Cognition by Telephone (BTACT); Executive functioning = z-score of stop and go switch task on BTACT.
