Redesigning the Central Eight: Introducing the M-PACT Six

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.
