The purpose of this study was to quantify the general cancer support activities that long‐term carers of head and neck cancer (HNC) survivors engage in; and the relationships between these care activities and psychological well‐being. Respondents answered a survey detailing their caring activities, the amount of time that they spent on those activities and how comfortable they felt engaging in them. Psychological well‐being was assessed by the Depression Anxiety Stress Scales‐21. A total of 197 carers took part in the study. The majority (76%) were women, mean age 57.4.
