Interdependence, bonding and support are associated with improved mental wellbeing following an outdoor team challenge

Social relationships and mental health are functionally integrated throughout the lifespan. Although recent laboratory‐based research has begun to reveal psychological pathways linking social interaction, interdependence, bonding and wellbeing, more evidence is needed to integrate and understand the potential significance of these accounts for real‐world events and interventions. In a questionnaire‐based, repeated measures design, we measured the wellbeing of 13‐ to 19‐year‐old participants (n = 226) in the Ten Tors Challenge (United Kingdom) 7–10 days before (T1) and after (T4) the event. Immediately before (T2) and after (T3) the event, we administered measures of team bonding, perceived and experienced interdependence, perceived and received support, physical pain and fatigue, and performance satisfaction. There was a significant increase in participants' wellbeing (pre‐to‐post event). Post‐event social bonding and performance satisfaction positively predicted the wellbeing increase. Bonding was, in turn, positively predicted by experienced interdependence, received support, pain and fatigue, and the sense of having done better as a team than expected. Results provide novel field‐based evidence on the associations between meaningful bonds of mutual reliance in a challenging team event and adolescent wellbeing. Team challenge events potentially offer effective contexts for forging social interactions, interdependencies, and bonds that can support mental and physical health.
