The "Inventory of Statements About Self-Injury" (ISAS) is one of the most widely used and reliable psychometric tools for assessing non-suicidal self-injury (NSSI) and its motivations. The Russian adaptation of the ISAS, involving patients with nonpsychotic psychiatric disorders, demonstrated high internal consistency and a two-factor structure similar to the original. However, the reliability and suitability of ISAS in a non-clinical population remain unclear.
To adapt the ISAS in Russian, evaluate its psychometric properties, and analyze its factor structure in a sample of Russian university students.
The psychometric properties and factor structure of the adapted ISAS version were evaluated through an anonymous online survey of Russian university students. Respondents had reported lifetime NSSI and scored above 4 on the ISAS-Functions subscale. Exploratory and confirmatory factor analysis (EFA/CFA) were performed on two randomly formed subgroups to evaluate the factor structure of ISAS. Additionally, the associations between the identified ISAS factors and the presence of suicidal thoughts and attempts over a lifetime and in the week before their participation in the study, as well as seeking psychiatric and/or psychotherapeutic care over a lifetime, were analyzed.
The survey included 3,919 participants, of whom 1,149 (29.3%; 88.0% female) reported NSSI, with a median age of 20 (18; 22) years. The Russian ISAS demonstrated high internal consistency (Cronbach's alpha = 0.851). EFA results supported the original two-factor structure. CFA results suggested an alternative three-factor structure of the ISAS, including "Signal", "Regulation", and "Influence" factors. Suicidal attempts were associated with the factors "Regulation" and "Influence", suicidal thoughts with "Regulation" and female gender, and the seeking of psychiatric and/or psychotherapeutic care with "Regulation" and age.
The adapted ISAS in Russian is a reliable tool with high internal consistency. The study proposed a three-factor structure, indicating a greater heterogeneity of the NSSI phenomenon compared to earlier understandings. The study demonstrated the association between two of the three identified factors with suicidal behavior and thoughts, and the seeking of psychiatric care.
“自我伤害陈述量表”（ISAS）是评估非自杀性自我伤害（NSSI）及其动机最广泛使用且可靠的心理测量工具之一。对涉及非精神病性精神障碍患者的ISAS进行的俄语改编显示出较高的内部一致性和与原版相似的双因素结构。然而，ISAS在非临床人群中的可靠性和适用性仍不明确。
将ISAS改编为俄语版本，评估其心理测量特性，并分析其在俄罗斯大学生样本中的因素结构。
通过对俄罗斯大学生进行匿名在线调查，评估改编后的ISAS版本的心理测量特性和因素结构。受访者报告有终生NSSI经历且在ISAS功能分量表上得分高于4分。对两个随机形成的亚组进行探索性和验证性因素分析（EFA/CFA），以评估ISAS的因素结构。此外，分析了所确定的ISAS因素与终生及参与研究前一周内自杀想法和自杀未遂的存在情况之间的关联，以及终生寻求精神科和/或心理治疗护理的情况。
调查包括3919名参与者，其中1149名（29.3%；88.0%为女性）报告有NSSI，中位年龄为20（18；22）岁。俄语版ISAS显示出较高的内部一致性（克朗巴哈α系数=
0.851）。EFA结果支持原版的双因素结构。CFA结果表明ISAS存在另一种三因素结构，包括“信号”、“调节”和“影响”因素。自杀未遂与“调节”和“影响”因素相关，自杀想法与“调节”因素和女性性别相关，寻求精神科和/或心理治疗护理与“调节”因素和年龄相关。
改编后的俄语版ISAS是一种具有高内部一致性的可靠工具。该研究提出了一种三因素结构，表明与早期认识相比，NSSI现象具有更大的异质性。该研究证明了所确定的三个因素中的两个与自杀行为和想法以及寻求精神科护理之间的关联。
