The authors developed the Self-Injurious Thoughts and Behaviors Interview (SITBI) and evaluated its psychometric properties. The SITBI is a structured interview that assesses the presence, frequency, and characteristics of a wide range of self-injurious thoughts and behaviors, including suicidal ideation, suicide plans, suicide gestures, suicide attempts, and nonsuicidal self-injury (NSSI). This initial study, based on the administration of the SITBI to 94 adolescents and young adults, suggested that the SITBI has strong interrater reliability (average kappa = .99, r = 1.0) and test-retest reliability (average kappa = .70, intraclass correlation coefficient = .44) over a 6-month period. Moreover, concurrent validity was demonstrated via strong correspondence between the SITBI and other measures of suicidal ideation (average kappa = .54), suicide attempt (kappa = .65), and NSSI (average kappa = .87). The authors concluded that the SITBI uniformly and comprehensively assesses a wide range of self-injury-related constructs and provides a new instrument that can be administered with relative ease in both research and clinical settings.
作者开发了自伤想法与行为访谈（SITBI）并评估了其心理测量特性。SITBI是一种结构化访谈，用于评估一系列自伤想法与行为的存在情况、频率及特征，包括自杀意念、自杀计划、自杀姿态、自杀未遂以及非自杀性自伤（NSSI）。这项基于对94名青少年及青年成人进行SITBI访谈的初步研究表明，SITBI在6个月期间具有较高的评分者间信度（平均kappa系数 = 0.99，r = 1.0）和重测信度（平均kappa系数 = 0.70，组内相关系数 = 0.44）。此外，通过SITBI与其他自杀意念测量方法（平均kappa系数 = 0.54）、自杀未遂测量方法（kappa系数 = 0.65）以及NSSI测量方法（平均kappa系数 = 0.87）之间的高度一致性，证明了其同时效度。作者得出结论，SITBI能够统一且全面地评估一系列与自伤相关的结构，并提供了一种新工具，可在研究和临床环境中相对轻松地进行应用。
