Notes: The general population means for negative affect, psychological well‐being, and social satisfaction are 50, and the SD is 10.
There were 41 participants diagnosed with non‐amnestic MCI, and 45 participants diagnosed with amnestic MCI.
Controlling for age, sex, race, education, marital status, and depressive symptoms.
Age range 75–94.
After the onset of the COVID‐19 pandemic, I‐CONECT's data collection modality changed. The research team used the telephone MoCA because we could not conduct the assessment in person. The possible scale range for in‐person MoCA is 0–30, and for telephone MoCA is 0–22. A higher MoCA score indicates better global cognition. Of the 127 participants who had in‐person MoCA assessments, 70 were diagnosed with MCI, and 57 had normal cognition. Among the 36 participants who had MoCA test over phone calls, 16 had MCI, and 20 had normal cognition.
GDS possible scale range 0–15, sample score range 0–7.
Lubben Social Network Scale (LSNS‐6) score possible scale range 0–30, sample score range 3–29.
Abbreviations: GDS, Geriatric Depression Scale; MCI, mild cognitive impairment; MoCA, Montreal Cognitive Assessment; SD, standard deviation.
