Measured using the short-form University of California, Los Angeles (UCLA) Loneliness Scale (aka ULS-4). This is a 4-item scale designed to measure one's subjective feelings of loneliness as well as feelings of social isolation. The questions are: no one really knows me well, people are around me but not with me, I feel in tune with the people around me, I can find companionship when I want it. Subjects rate each item as either O ("I often feel this way"), S ("I sometimes feel this way"), R ("I rarely feel this way"), N ("I never feel this way"). Responses are summed over the four questions and rescaled to a 0-1 scale.
