The healthcare focus is on the children; however, the parents often worry about their children's health and future but are seldom offered any counselling or guidance. Aim: The aim of this study was to investigate the effectiveness of two group-based behavioural interventions on stress and burnout among parents of children with chronic conditions. Design, participants and setting: After a waiting list control period (n = 28), parents were offered either a cognitive behavioural (CBT, n = 10) or a mindfulness program (MF, n = 9). Results: Both interventions decreased significantly stress and burnout. The within-group effect sizes were large in both interventions (CBT, g = 1.28-1.64; MF, g = 1.25-2.20). Conclusions: Hence, the results of this pilot study show that treating a group using either CBT or mindfulness can be an efficient intervention for reducing stress levels and burnout in parents of children with chronic conditions.
