The Measurement of Services and Supports (MOSS) project commenced in 2005, with the initial aim of developing and trialing a tool that would evaluate the outcomes of therapy and psychology services delivered by Scope’s Therapy, Psychology and Related Services teams (previously known as Specialist Services). There are a number of key drivers that have influenced the MOSS project from its inception. These include: • Scope’s Strategic direction; • The State Disability Plan 2002-2012 (Victorian Department of Human Services, 2002); • A desire to provide evidence for funding bodies relating to the effectiveness of the support delivered by Therapy, Psychology and Related Services; and • A desire to ensure that Therapy, Psychology and Related Services support is based on evidence.
