Respondents were also asked if they ever experienced any other extremely traumatic or life-threatening event not already captured in the TE checklist and, if so, about the respective NOE and AOE. Finally, respondents were asked about any TE that was not endorsed due to its private nature. The question posed was as follows: ‘Sometimes people have experiences they don’t want to talk about in interviews. I won’t ask you to describe anything like this, but, without telling me what it was, did you ever have a traumatic event that you didn’t tell me about because you didn’t want to talk about it?’ Respondents who reported a private TE were asked about NOE and AOE.
