Non-suicidal self-injury (NSSI) is defined as the repetitive deliberate destruction of one's body tissue without suicidal intent and is frequently repetitive. The aim of this study was to examine the psychometric properties of the Inventory of Statements About Self-injury (ISAS), a measure designed to comprehensively assess 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 529 high school students who had performed at least one NSSI behavior. The internal consistency and test-retest reliability of the scale were examined; for construct validity, the relationship between the Turkish form of the ISAS and various criteria scales was examined, and confirmatory factor analysis (CFA) was conducted.
Consistent with previous research, factor analysis of the functions scale confirmed the good-fit of the original's 2-dimension model (c²=243; s.d. = 59; NCI (c²/sd) = 4; RMSEA = 0.08 (.07-.09); CFI=0.97; NFI=0.97). In order to test the scale for construct validity, the Brief Symptom Inventory and Suicide Probability Scale were administered to participants, in addition to the ISAS, and the correlations with clinical constructs (e.g., suicidality, depression, anxiety) were in the expected direction. Also the reliability analysis revealed that the ISAS subscales demonstrated high internal consistency.
In the light of the findings, it was concluded that the Turkish version of ISAS could be used as a reliable and valid tool in assessing non-suicidal self-injury in research and treatment contexts.
非自杀性自伤（NSSI）被定义为反复故意破坏自己的身体组织且无自杀意图，并且常常具有重复性。本研究的目的是检验自伤陈述量表（ISAS）的心理测量特性，该量表旨在全面评估非自杀性自伤（NSSI）。ISAS评估了NSSI的13种功能，以及12种NSSI行为的频率。
对529名至少有过一次NSSI行为的高中生施测ISAS。检验了该量表的内部一致性和重测信度；为检验结构效度，考察了ISAS土耳其语版本与各种标准量表之间的关系，并进行了验证性因素分析（CFA）。
与先前研究一致，功能分量表的因素分析证实了原始二维模型的良好拟合（χ² = 243；标准差 = 59；NCI（χ²/标准差） = 4；RMSEA = 0.08（0.07 - 0.09）；CFI = 0.97；NFI = 0.97）。为检验该量表的结构效度，除ISAS外，还对参与者施测了简明症状量表和自杀概率量表，与临床构念（如自杀倾向、抑郁、焦虑）的相关性符合预期方向。可靠性分析还表明，ISAS分量表具有较高的内部一致性。
根据研究结果得出结论，ISAS的土耳其语版本可作为在研究和治疗背景下评估非自杀性自伤的可靠且有效的工具。
