Nonsuicidal self-injury (NSSI) is a severe and prevalent mental health problem (
The main aim of this study is to validate the P-NSSI-IAT by assessing its ability to detect prior NSSI behaviour in a sample of clinical patients.
We will target patients who receive outpatient treatment for various conditions. Participants will first complete the P-NSSI-IAT. Next, they will be asked how many times they have intentionally cut or carved their skin without intending to kill themselves in the past twelve months and the past 30 days and how likely they would be to intentionally cut or carve their skin without intending to kill themselves in the future.
The registered study is the first to examine the clinical utility of a new implicit measure for prior NSSI behaviour (the P-NSSI-IAT). It will provide an answer to the question whether the P-NSSI-IAT allows detection of self-rated prior NSSI and future likelihood of NSSI in a sample of clinical patients.
