BACKGROUND
With increasing levels of suicide and self-harm behaviour in the criminal justice system professionals would benefit from a tool that can identify individuals who may be at risk of self-harm and/or suicidal behaviour.
METHOD
The Suicide Concerns for Offenders in the Prison Environment (SCOPE) tool was originally devised and validated in six UK prisons between 2003 and 2004. The goal of this study is to re-evaluate the SCOPE using Rasch methodology to produce a psychometrically robust instrument. Data were presented from 1051 SCOPE assessments of male and female offenders.
RESULTS
The analysis produced a revised SCOPE-2 tool reducing the tool from a 27 to a 19 items and simplifying the categorical six point scale to a four item scale.
CONCLUSIONS
Further validation of the new SCOPE-2 tool is required in samples of male and female prisoners to assess different cut-off points for clinical and policy use.
背景
随着刑事司法系统中自杀和自残行为的增多，专业人员将受益于一种能够识别可能有自残和/或自杀行为风险的人的工具。
方法
《监狱环境中罪犯的自杀关注》（SCOPE）工具最初是在 2003 年至 2004 年期间在六个英国监狱中设计和验证的。本研究的目的是使用 RASCH 方法重新评估 SCOPE，以生成具有心理测量学稳健性的工具。数据来自 1051 名男性和女性罪犯的 SCOPE 评估。
结果
分析产生了一个修订后的 SCOPE-2 工具，将工具从 27 项减少到 19 项，并将六分制的分类简化为四分制。
结论
需要在男性和女性囚犯样本中进一步验证新的 SCOPE-2 工具，以评估临床和政策使用的不同截止值。
