Reliability of the Service Need Assessment Profile (SNAP): A measure of support for people with disabilities (original) (raw)

Journal of Intellectual and Developmental Disability, 2005

Abstract

ABSTRACT Background Measures for estimating costs associated with the provision of disability services in Australia have not previously been available. Because such instruments are scarce worldwide, decisions about funding services have relied more on historical precedent and less on individual need. Recognising the necessity for an objective measure, Gould (1998) developed the Service Need Assessment Profile (SNAP), a scale for estimating the support needs and associated costs for people with disabilities. Method This study examined the technical properties of SNAP using assessment data from 318 adults (190 males and 128 females), mean age 43 years, with a range of disability types and levels of severity, residing in supported accommodation around metropolitan Adelaide, South Australia. Results Results suggest that SNAP's reliability varies across different sub‐groups and across domains. Conclusion Using SNAP assessments as a method for allocating funds/resources across the disability sector should be approached cautiously, bearing in mind the reported limitations.
