Although many adolescent risk assessment tools include an emphasis on dynamic factors, little research has examined the extent to which these tools are capable of measuring change. In this article, we outline a framework to evaluate a tool's capacity to measure change. This framework includes the following: (a) measurement error and reliable change, and (b) sensitivity (i.e., internal, external, and relative sensitivity). We then used this framework to evaluate the Structured Assessment of Violence Risk in Youth (SAVRY) and Youth Level of Service/Case Management Inventory (YLS/CMI). Research assistants conducted 509 risk assessments with 146 adolescents on probation (101 male, 45 female), who were assessed every 3 months over a 1-year period. Internal sensitivity (i.e., change over time) was partially supported in that a modest proportion of youth showed reliable changes over the 3-, 6-, and 12-month follow-ups. External sensitivity (i.e., the association between change scores and reoffending) was also partially supported. In particular, 22% of the associations between change scores and any and violent reoffending were significant at a 6-month follow-up. However, only 1 change score (i.e., peer associations) remained significant after the Bonferroni correction was applied. Finally, relative sensitivity was not supported, as the SAVRY and YLS/CMI was not more dynamic than the Psychopathy Checklist: Youth Version (PCL:YV). Specifically, the 1-year rank-order stability coefficients for the SAVRY, YLS/CMI, and PCL:YV Total Scores were .78, .75, and .76, respectively. Although the SAVRY and YLS/CMI hold promise, further efforts may help to enhance sensitivity to short-term changes in risk. (PsycINFO Database Record
虽然许多青少年风险评估工具都强调动态因素,但很少有研究检验这些工具在多大程度上能够衡量变化。在本文中,我们概述了一个评估工具衡量变化能力的框架。该框架包括以下内容:(a)测量误差和可靠变化,以及(b)敏感性(即内部、外部和相对敏感性)。然后,我们使用该框架评估了《青少年暴力风险结构化评估》(SAVRY)和《青少年服务/案例管理清单》(YLS/CMI)。研究助理对 146 名缓刑中的青少年(101 名男性,45 名女性)进行了 509 次风险评估,这些青少年在 1 年内每 3 个月接受一次评估。内部敏感性(即随时间的变化)得到了部分支持,因为相当一部分青少年在 3、6 和 12 个月的随访中表现出可靠的变化。外部敏感性(即变化分数与再犯罪之间的关联)也得到了部分支持。特别是,在 6 个月的随访中,变化分数与任何和暴力再犯罪之间的 22%的关联具有统计学意义。然而,只有 1 个变化分数(即同伴关系)在进行了 Bonferroni 校正后仍然具有统计学意义。最后,相对敏感性没有得到支持,因为 SAVRY 和 YLS/CMI 并不比《青少年心理病理检查表》(PCL:YV)更具动态性。具体来说,SAVRY、YLS/CMI 和 PCL:YV 总得分的 1 年秩相关系数分别为.78、.75 和.76。尽管 SAVRY 和 YLS/CMI 有一定的前景,但进一步的努力可能有助于提高对风险短期变化的敏感性。
