The present study reports the psychometric properties of the Inventory of Statements About Self-injury (ISAS), a measure designed to comprehensively assess the functions of non-suicidal self-injury (NSSI). The ISAS assesses 13 functions of NSSI, as well as the frequency of 12 NSSI behaviors. The ISAS was administered to 235 young adults from a college population who had performed at least one NSSI behavior. Consistent with previous research, ISAS functions comprised two factors representing interpersonal and intrapersonal functions. In addition, the ISAS factors exhibited excellent internal consistency and expected correlations with both clinical constructs (e.g., borderline personality disorder, suicidality, depression, anxiety) and contextual variables (e.g., tendency to self-injure alone). Findings support the reliability and validity of the ISAS. The ISAS may be useful in research and treatment contexts as a comprehensive measure of NSSI functions.

Non-suicidal self-injury in United States adults: prevalence, sociodemographics, topography and functions (2011, methodology): “…the SITBI, two functional items were included from the Inventory of Statements about Self-injury (Klonsky & Glenn, 2009), a reliable and valid measure of NSSI functions, because they represent functions that have been frequently endorsed in past research (Klonsky, 2007 ; Klonsky & Glenn, 2009).”

Non-Suicidal Self-Injury Within Offender Populations: A Systematic Review (2012, methodology): “Self-report measures include the Deliberate Self-harm Inventory (Gratz, 2001 ), which assesses topography of NSSI history, and the Inventory for Self-Statements about Self-Injury (Klonsky & Glenn, 2009 ) and Functional Assessment of Self-Mutilation (Lloyd, Kelley, & Hope, 1997), which assess motiv”
The relationship between non-suicidal self-injury and suicidality (2016, methodology): “This is consistent with studies finding NSSI to serve predominantly an intrapersonal, emotion-regulation function (Klonsky, 2007; Klonsky & Glenn, 2009; Nock & Prinstein, 2004).”
Examining the link between nonsuicidal self-injury and suicidal behavior: a review of the literature and an integrated model. (2012, background): “Several researchers have concluded that NSSI is a form of coping behavior, on the basis of research that individuals report engaging in NSSI to regulate their affective and social experiences (Klonsky & Glenn, 2009; Nock & Prinstein, 2005).”
