The UCLA Loneliness Scale- Version348 was used to measure one’s own subjective feelings of loneliness as well as feelings of social isolation, in its Italian version.49 It is a 20-item scale on a 4-point Likert scale from 1 (I never feel this way) to 4 (I often feel this way) (e.g., “I am unhappy doing so many things alone”, “I feel isolated from others”). This measure has high internal consistency (Cronbach’s alpha = 0.96)48 and a test-retest correlation over two-month of 0.73. The Cronbach’s alpha for the present sample was 0.83.
