RESUMEN
The COVID-19 pandemic has left many individuals suffering from "connection deficit disorder" given changes to the way we work, go to school, socialize, and engage in daily activities. Young adults affected by cancer between the ages of 18-39 have known this connection deficit long before the pandemic. Being diagnosed and treated for cancer during this time can significantly disrupt engagement in important educational, career, social, and reproductive pursuits, and contribute to increased stress, anxiety, depression, and other negative outcomes. Experiencing meaningful connection-with nature, with peers who understand, and with oneself, may help assuage this adverse effect of disconnect. A single arm within-subjects program evaluation was conducted to examine outcomes following participation in immersive, multi-night, mindfulness-based treks in nature in a sample of young adults (n = 157) and caregivers (n = 50) affected by cancer from 2016-2021. Pre to post-trek changes included significant (p < 0.001) self-reported improvements in feeling connected to nature (d = 0.93-0.95), peers (d = 1.1-1.3), and oneself (d = 0.57-1.5); significant (p < 0.001) improvements on PROMIS Anxiety (d = 0.62-0.78), Depression (d = 0.87-0.89), and Sleep Disturbance (d = 0.37-0.48) short forms; and significant (p < 0.05) changes in pro-inflammatory biomarkers (d = 0.55-0.82). Connection-promoting experiences like this have the potential to improve health and wellbeing in this population and serve as a model for others.
