“…Among the 21 quantitative and mixed-method studies, 12 (57%) studies used original or modified UCLA in assessing loneliness ( Abedini et al, 2020 ; Cacioppo et al, 2017 ; Ebimgbo et al, 2021 ; Gonyea et al, 2018 ; Hawkley & Kocherginsky, 2018 ; Igbokwe et al, 2020 ; Mannes et al, 2016 ; Ntozini & Abdullahi, 2021 ; Ojagbemi & Gureje, 2019 ; Olawa et al, 2019 ; Olawa & Idemudia, 2020 ; Taylor & Nguyen, 2020 ). The remaining eight studies used a modified version of the de Jong-Gierveld Loneliness Scale ( Han et al, 2017 ), a 20-point index measuring social contact ( Creecy et al, 1983 ), the Social Isolation component of a Patient-Reported Outcomes Measurement Information System ( Yoo-Jeong et al, 2020 ), single-item question, for example, “did you feel lonely for much of the day yesterday or in the past seven days?” ( Choi et al, 2021 ; Phaswana-Mafuya & Peltzer, 2017 ; Taylor et al, 2018 ; Victor et al, 2012 ), or two-item questions, for example, “are there times when you have a feeling of loneliness and what do you think needs to be done to reduce this loneliness?” ( Nzabona et al, 2016 ).…”
