Effectiveness of acceptance commitment therapy for head and neck cancer patients with body image distress in China: a study protocol for randomised controlled trial

Introduction The head and neck comprise vital organs and are apparent human body parts. Tumours here impair physical and sensory functions as well as appearance and social interactions, leading to body image distress (BID) and threatening mental health and quality of life. Acceptance and commitment therapy has shown effectiveness in improving BID in groups such as breast cancer patients. This study aims to apply this therapy to intervene in head and neck cancer (HNC) patients, aiming to improve BID and promote better psychological well-being.Methods and analysis This study is a prospective, parallel-group, randomised controlled trial. A total of 64 HNC patients will be allocated to either an intervention group or a control group. The intervention group will engage in a 3 week, six-session group-based acceptance and commitment therapy programme, while the control group will receive standard treatment. The primary outcome is cancer-related BID, and secondary outcomes are HNC-related BID, psychological flexibility, coping style and psychological distress. These indicators will be measured at baseline, postintervention and 1 month following the intervention’s completion.Ethics and dissemination The trial has received approval from the Institutional Review Board of Shanghai Proton and Heavy Ion Hospital (2308-67-02). The study results will be shared through peer-reviewed journals and conferences.Trial registration number ChiCTR2300077863.
