In this episode of The Criminologist Podcast, host Joseph Arvidson is joined by Shawn Trusten and Phil Galli, co-creators of the Core 4 Survey and Intervention, an innovative framework that breaks down social support into four key domains: Instrumental, Expressive, Perceived, and Received.

Built on years of case management experience and field testing, the Core 4 model helps practitioners move beyond the binary “pro-social/anti-social” lens and instead gain a nuanced, actionable understanding of the social networks that influence client behavior. This episode explores how the Core 4 tool bridges assessment and intervention—serving as a roadmap for client-centered case planning and long-term behavioral change.
