| Measure | Time frame |
|---|---|
| Part 1: The experience of mental images is assessed with one item (yes/no). Part 2: The frequency of NSSI is assessed at baseline with the DSHI and the BSL-95. The frequency of NSSI is further observed with the Diary. The frequency of mental images on NSSI is asked upon at baseline regarding the week prior to assessment. It is further observed with the diary. The affect that was present after the mental image is measured at baseline and daily with the positive and negative affective state (PANAS). Certain characteristics of mental images such as vividness, compellingness, controllability, nowness, distress, and soothingness are measured with one items each (scale 1-9). Other features such as content or associated cognitions are assessed with an open-ended question. All imagery features are assessed both at baseline and daily. The feeling of entrapment is measured at baseline with the Entrapment Scale, and with one item daily (scale 1-9), along with the feeling of defeat with one item daily (scale 1-9). | — |
