Adam was a 21-year-old white British man with a 2% total body surface area (TBSA) full-thickness flame burn to his hand following a workplace accident six months before the intervention. He was employed full-time and was living with his partner at the time of the accident. After the accident, Adam developed post-traumatic stress disorder (PTSD), which had been treated successfully through trauma-focused psychological therapy by the second author (AT). In addition, Adam developed appearance anxiety due to scarring, and treatment for this began after his symptoms of PTSD had reduced to subclinical levels, as determined by the treating clinical psychologist (AT) and his self-report. He did not have a history of psychological problems before the accident but he reported that he had always had a degree of poor body image but that this had never impacted on his daily functioning. He worried about how others would perceive his hand, covered his scars, avoided holding hands with his partner and withdrew socially. This negatively impacted his relationship and social life. Adam received eight sessions of ACT. He cancelled and rearranged four sessions and had no non-attendances.
