The main aim of the present study was to confirm the two-factor structure of the Inventory of Statements About Self-injury- Part II (ISAS-II), analyze its psychometric properties and test-retest reliability of Parts I and II of the ISAS.
The sample was composed of 355 Spanish participants diagnosed with eating disorders or borderline personality disorder (mean age 27.89, standard deviation = 13.31; 315 women, 40 men). Two models proposed for the ISAS-II were analyzed by means of confirmatory factorial analysis.
A two-factor model was confirmed, and a model with self-care included in the intrapersonal factor was preferable. The ISAS-II showed positive correlations with emotional dysregulation. Test-retest reliability showed statistically significant correlations at 7 months (n = 123).
The ISAS-II is a valid instrument to assess nonsuicidal self-injury in Spanish populations, making it possible to assess these behaviors, which require valid and reliable measures worldwide.
本研究的主要目的是验证自我伤害陈述量表第二部分（ISAS-II）的两因素结构，分析其心理测量特性和 ISAS 的第一部分和第二部分的重测信度。
该样本由 355 名被诊断患有饮食失调或边缘型人格障碍的西班牙参与者组成（平均年龄 27.89，标准差=13.31；315 名女性，40 名男性）。通过验证性因素分析对 ISAS-II 提出的两种模型进行了分析。
确认了两因素模型，并且将自我关怀纳入人际因素的模型更可取。ISAS-II 与情绪失调呈正相关。7 个月时的重测信度显示出具有统计学意义的相关性（n=123）。
ISAS-II 是评估西班牙语人群非自杀性自伤的有效工具，使我们能够评估这些行为，这在全球范围内需要有效的和可靠的衡量标准。
