Non-suicidal self-injury (NSSI) is a serious public health problem prevalent among adolescents and young adults. The present study examines the factor structure, internal consistency, and validity of the Persian version of the Inventory of Statements About Self-injury (ISAS), a self-report measure designed to comprehensively assess non-suicidal self-injury (NSSI).
A total of 655 Iranian school-attending adolescents completed study measures online, and 246 youth (37.70 %) (M age = 15.38, SD ± 0.50; 53 % female) reported a history of NSSI at least once during their lifetime.
Confirmatory factor analysis supported the proposed two-factor model of ISAS (i.e., Interpersonal and Intrapersonal dimensions), which were internally consistent and yielded direct associations with converging correlates (e.g., depression, anxiety, irritability, and anger).
Findings indicated that the Persian version of the ISAS has sound psychometric properties and is a valid and reliable self-report measure of NSSI.
非自杀性自伤（NSSI）是青少年和青年中普遍存在的一个严重公共卫生问题。本研究考察了自伤陈述量表（ISAS）波斯语版本的因子结构、内部一致性和效度，该自陈式量表旨在全面评估非自杀性自伤（NSSI）。
共有655名伊朗在校青少年在线完成了研究测量，246名青少年（37.70%）（年龄中位数=15.38，标准差±0.50；53%为女性）报告在其一生中至少有过一次非自杀性自伤史。
验证性因素分析支持了ISAS提出的两因素模型（即人际维度和人际内维度），这两个维度内部一致，并与趋同的相关因素（如抑郁、焦虑、易怒和愤怒）有直接关联。
研究结果表明，ISAS波斯语版本具有良好的心理测量学特性，是一种有效且可靠的非自杀性自伤自陈式测量工具。
