There is currently no structured interview tool developed that comprehensively evaluates self-injurious thoughts and behaviors (SITB) in Korea. The Self-injurious Thoughts and Behaviors Interview (SITBI) collectively measures suicidal ideation, plans, gestures, attempts, and non-suicidal self-injuries (NSSI). The SITBI's reliability and validity have been established with it being widely used in English speaking countries. This study evaluated the psychometric validity of the Korean version of the SITBI (SITBI-K).
The SITBI's validity as a diagnostic assessment tool for NSSI and suicidal behavior disorder (SBD), as defined by the Diagnostic and Statistical Manual of Mental Disorders-5th edition, was examined. Analyses were performed on 108 university students reporting experiences of suicidal thoughts and behaviors (female 84.26%, mean age=22.10, ±SD 3.33).
The SITBI-K displayed excellent interrater reliability, with a credible test-retest reliability at two months. Construct validity examined the correlation between the SITBI-K's modules and approved the self-report results. Appropriate convergent and discriminant validities were obtained for suicidal ideation, plans, gestures, attempts, and NSSI.
The SITBI-K showed excellent psychometric validity at a level comparable to the original. Its clinical utility for both NSSI and SBD diagnoses was confirmed.
目前在韩国还没有开发出一种能全面评估自伤性想法和行为（SITB）的结构化访谈工具。自伤性想法和行为访谈（SITBI）综合测量自杀意念、计划、姿态、企图以及非自杀性自伤（NSSI）。SITBI的信效度已经得到确立，并且在英语国家被广泛使用。本研究评估了韩语版SITBI（SITBI-K）的心理测量效度。
考察了SITBI作为《精神疾病诊断与统计手册》第5版所定义的NSSI和自杀行为障碍（SBD）诊断评估工具的效度。对108名报告有自杀想法和行为经历的大学生进行了分析（女性占84.26%，平均年龄=22.10，标准差±3.33）。
SITBI-K显示出极好的评分者间信度，在两个月时具有可靠的重测信度。结构效度考察了SITBI-K各模块之间的相关性，并认可了自我报告结果。在自杀意念、计划、姿态、企图和NSSI方面获得了适当的聚合效度和区分效度。
SITBI-K显示出与原版相当的极好的心理测量效度。证实了其在NSSI和SBD诊断中的临床效用。
