“…The evidenced mechanisms of the effect of the PEER program provide further evidence to support the use of ACT and self‐compassion as therapeutic approaches when working with adolescents impacted by their own or a family member's cancer, particularly those experiencing higher levels of distress. Whilst previous literature evidences the benefits of these approaches for young people (Bluth et al, 2016 ; Bluth & Eisenlohr‐Moul, 2017 ; Ernst & Mellon, 2016 ; Halliburton & Cooper, 2015 ; Rodgers et al, 2018 ; Swain et al, 2015 ), people with cancer (Feros et al, 2013 ; Hulbert‐Williams et al, 2015 ) and those at the intersection of these groups (Campo et al, 2017 ; Patterson, McDonald, Ciarrochi, et al, 2017 ; Patterson et al, 2019 ; Patterson, McDonald, Kelly‐Dalgety, Luo, & Allison, 2021 ) has been relatively limited, these approaches were considered promising for this population because of their focus on non‐judgemental and compassionate acceptance of difficult thoughts and feelings brought on by cancer (Clarke et al, 2020 ; González‐Fernández & Fernández‐Rodríguez, 2019 ; Hayes et al, 2006 ; Hulbert‐Williams et al, 2015 ; Ing et al, 2019 ). Struggling with difficult thoughts and feelings is a reasonable response to the challenging life circumstance of a cancer diagnosis that is beyond one's control; being able to accept and live well with these emotions and cognitions, rather than engaging in the futility of trying to challenge or change them, may be more adaptive.…”
