Towards Field Consistency

​

Measuring and assessing non-suicidal self-injury (NSSI) is complex and various measuring systems have been created. To facilitate the use of reliable and validated measures, the ISSS has established a repository of measures available to ISSS members. Assessment tools listed below are included with the permission of the authors.

​
