Summary<\/span><\/h2>\n

The Ottawa Self-Injury Inventory (OSI) is a self-report measure used to assess nonsuicidal self-injury including frequency, types of self-injury, functions of the behaviour, potential addictive features of the behaviour, and motivation for change. There is an abbreviated version of the OSI known as the OSI-Functions inventory. Dr. Mary K Nixon was the lead author of the pen and paper version of the OSI in the early 2000’s, in addition to Paula Clourtier.<\/p>\n

We want to thank Dr. Mary K Nixon for sharing her expertise with us in the development of the electronic version and accompanying Assessment Guide. Several minor modifications have been made from the pen and paper version including addition of questions relating to social media.<\/i><\/p>\n

She is the Founding Editor of the Journal of the Canadian Association of Child and Adolescent Psychiatry and\u00a0 was the network leader for INSYNC (Interdisciplinary National Self-Injury in Youth Network of Canada), a group of researchers studying self-injury across Canada that was initiated in 2005. Dr Nixon has published a number of articles on self injury and co-edited and contributed to a number of chapters in the book \u2019Self Injury in Youth: The Essential Guide to Assessment and Interventions, Routledge Press, 2009\u2019.<\/i><\/p>\n
