 The study aimed to explore the acceptability of a web-based version of the volitional help sheet, VHS, for self-harm using the theoretical framework of acceptability, TFA. Participants rated the VHS positively in terms of effective attitude, self-efficacy, intervention coherence, and perceived effectiveness. Lower levels of perceived burden when using the VHS tool were more prevalent among younger adults, people of white ethnic backgrounds, and people without long-term health conditions. The study recommends improving formatting, burden, adding new situations and responses or amending existing ones, ethicality, and providing clearer instructions and further detail about the purpose of the VHS, intervention coherence, to improve acceptability among these groups.
