Nod is an app geared towards helping college students stay socially connected. There are five options users choose to indicate their desired level of social connection: “Keeping in touch from afar”, “Taking on goals together”, “Connecting through kindness”, “Staying tapped into my college”, and “Deepening connections”. Based on these rankings users are given personalized activities they can perform to support their choices. Users also have the ability to change up their preferences and explore all the activities. Some examples of activities include: “Contact someone you have not heard from in a while”, and “Read books to children online”. Another feature is the Reflect section of the app. This section aims to bring more self awareness through interactive illustrations and guided meditation.

Research on this App

In a study published in 2020, 221 (mean age 18.7 years, 59% female) first-year college students were randomized to receive either immediate access to Nod (n=100) or access after 4 weeks. (n=121). Participant were assessed for their levels of loneliness (using the UCLA-8 scale), and depression and anxiety (using PHQ-9 and GAD-7 scales). Levels of social anxiety, sleep quality, perceived social support, campus belonging, social adjustment to college, intention to return (to college), and user experience in the app were also measured. There were no significant condition differences in loneliness at week 4. However, there was a significant condition-by-baseline depression interaction to predict week-4 loneliness. Simple slope analyses indicated that baseline depression positively predicted week-4 loneliness among control participants, but not among experimental participants, suggesting that Nod buffered participants with high baseline depression scores from experiencing heightened midquarter loneliness.
