CASE questionnaire [18]. Participants were also asked whether they sought medical help and how they felt following the most recent time, and whether they had ever seriously wanted to kill themselves when self-harming. The whole sample were then asked whether they had ever felt life was not worth living, wished they were dead and away from it all, thought of killing themselves, or made plans to kill themselves; questions which were drawn from a study of suicidal feelings in the USA [19].
