The Ottawa Self-Injury Inventory (OSI) is a self-report measure that offers a comprehensive assessment of nonsuicidal self-injury (NSSI), including measurement of its functions and addictive features. In a preliminary investigation of self injuring college students who completed the OSI, exploratory analysis revealed four function factors (Internal Emotion Regulation, Social Influence, External Emotion Regulation and Sensation Seeking) and a single Addictive Features factor. Rates of NSSI are particularly high in inpatient psychiatry youth. The OSI can assistin both standardizing assessment regarding functions and potential addictive features and aid case formulation leading to informed treatment planning. This report will describe a confirmatory factor analysis (CFA) of the OSI on youth hospitalized in a psychiatric unit in southwestern Ontario.
Demographic and self-report data were collected from all youth consecutively admitted to an adolescent in-patient unit who provided consent or assent.
The mean age of the sample was 15.71 years (SD = 1.5) and 76 (81 %) were female. The CFA proved the same four function factors relevant, as in the previous study on college students (χ (2)(183) = 231.98, p = .008; χ (2)/df = 1.27; CFI = .91; RMSEA = .05). The model yielded significant correlations between factors (rs = .44-.90, p < .001). Higher NSSI frequency was related to higher scores on each function factor (rs = .24-.29, p < .05), except the External Emotion Regulation factor (r = .11, p > .05). The factor structure of the Addictive Features function was also confirmed (χ (2)(14) = 21.96, p > .05; χ (2)/df = 1.57; CFI = .96; RMSEA = .08). All the items had significant path estimates (.52 to .80). Cronbach's alpha for the Addictive Features scale was .84 with a mean score of 16.22 (SD = 6.90). Higher Addictive Features scores were related to more frequent NSSI (r = .48, p < .001).
Results show further support for the OSI as a valid and reliable assessment tool in adolescents, in this case in a clinical setting, where results can inform case conceptualization and treatment planning.
渥太华自我伤害量表（OSI）是一种自我报告测量工具，可对非自杀性自我伤害（NSSI）进行全面评估，包括对其功能和成瘾特征的测量。在一项针对完成OSI的自我伤害大学生的初步调查中，探索性分析揭示了四个功能因素（内部情绪调节、社会影响、外部情绪调节和感觉寻求）和一个单一的成瘾特征因素。NSSI发生率在住院精神科青年中尤其高。OSI有助于规范对功能和潜在成瘾特征的评估，并有助于病例制定，从而制定明智的治疗计划。本报告将描述对安大略省西南部一家精神病科住院青年的OSI进行的验证性因素分析（CFA）。
从所有连续入住青少年住院部并提供同意或赞同的青年中收集人口统计学和自我报告数据。
样本的平均年龄为15.71岁（标准差=1.5），76名（81%）为女性。CFA证明了与之前对大学生的研究中相同的四个功能因素相关（χ(2)(183)=231.98，p=.008；χ(2)/自由度=1.27；CFI=.91；RMSEA=.05）。该模型在各因素之间产生了显著相关性（rs=.44-.90，p<.001）。较高的NSSI频率与每个功能因素的较高得分相关（rs=.24-.29，p<.05），外部情绪调节因素除外（r=.11，p>.05）。成瘾特征功能的因素结构也得到了证实（χ(2)(14)=21.96，p>.05；χ(2)/自由度=1.57；CFI=.96；RMSEA=.08）。所有项目都有显著的路径估计值（.52至.80）。成瘾特征量表的克朗巴哈α系数为.84，平均得分为16.22（标准差=6.90）。较高的成瘾特征得分与更频繁的NSSI相关（r=.48，p<.001）。
结果进一步支持OSI作为青少年有效且可靠的评估工具，在本研究中是在临床环境中，其结果可为病例概念化和治疗计划提供参考。
