Since their seminal work, Andrews and Bonta outlined the Central Eight assessment domains. As the landscape and utility of criminal justice assessments extended, tool developers expanded upon their initial development principles searching to further risk prediction gains. However, often overlooked in recent advancements is the foundation and usage of associated needs assessments. As a critical component of contemporary tools, particularly for youth, results of needs assessments identify and prioritize program placement. These additional tools comprise domain subscales that represent common predictors of need. Due to their latent nature, need assessment requires careful development and assessments of construct validity. While important, examinations of construct validity are seldom completed for contemporary tools, and their results rarely used for meaningful tool improvements. The current study describes the needs assessment development of the Modified Positive Achievement Change Tool (MPACT). Substantial psychometric evidence of construct validity is provided, describing the tool’s updated, six needs constructs.

自开创性工作以来，安德鲁斯（Andrews）和邦塔（Bonta）概述了中央八个评估领域。随着刑事司法评估的范围和实用性的扩展，工具开发人员扩展了其最初的开发原则，以寻求进一步的风险预测收益。但是，在最近的进展中经常忽略的是相关需求评估的基础和使用。作为现代工具（尤其是针对年轻人）的重要组成部分，需求评估的结果确定并确定了计划的优先级。这些其他工具包括代表需求的常见预测因素的领域子量表。由于其潜在性，需要评估需要仔细开发和评估构造的有效性。尽管很重要，但对于现代工具很少能进行构造效度的检验，其结果很少用于有意义的工具改进。当前的研究描述了改进的积极成就变更工具（MPACT）的需求评估开发。提供了构造有效性的大量心理计量证据，描述了该工具的最新六种需求构造。
