Outcome Measures

Primary Outcomes (4)

  • Mean change in loneliness

    Loneliness will be measured using the UCLA Loneliness Scale. A 20-item scale designed to measure one's subjective feelings of loneliness as well as feelings of social isolation. Participants rate each item as 1 (never), 2 (rarely), 3 (sometimes) or 4 (often). The scores range from 20-80 with higher scores indicating worse outcome.

    Baseline to 6 months

  • Mean change in anxiety

    Anxiety will be measured using the PROMIS tool. The scores range from 4-20 with higher scores indicating worse outcome.

    Baseline to 6 months

  • Mean change in depression

    Depression will be measured using the PROMIS tool. The scores range from 4-20 with higher scores indicating worse outcome.

    Baseline to 6 months

  • Mean change in social interactions

    Duke Social Support Index assesses several domains of perceived social support, including social network size, social interaction, social satisfaction, and instrumental social support. Higher scores indicate a higher quality of social interactions. Scores range from 0 to 37.
