“…Perceived social isolation, often used interchangeably with loneliness, is a similar subjective measure that also includes feeling like a stranger to others, barely known, avoided, detached from others, and isolated even when not alone (Cimino et al, 2023; PROMIS-SI, 2021; Santini et al, 2020). Social isolation (sometimes referred to as social disconnectedness) is an objective state of having lack of (or limited) social contact and is assessed through measures such as, small social network size, infrequent contact with others, and living alone (Cimino et al, 2023; National Academies of Sciences, Engineering, and Medicine [NASEM], 2020; Santini et al, 2020). It is worth noting that an individual may be surrounded by people and have many social contacts but still experience loneliness, whereas objective social isolation, which reflects actual time alone or without social company may not elicit feelings of loneliness.…”
