Session Abstract: 

Although needs assessments are an evaluation requirement for most federally funded programs, guidance related to specific methodological approaches and best practices can vary by funding institution. This lack of clear guidelines has resulted in a disjointed patchwork, as individual jurisdictions attempt to fulfill funding obligations with limited resources. The aim of this talk is to describe an approach used to conduct a HRSA-required needs assessment of Ryan White-funded (RW) services in Los Angeles County. Use of these techniques yielded a representative sample of patients in the local RW system. Patient-level weighting expanded the sample from 400 to 18,912 persons, consistent with the 19,915 clients in the system. Topics related to application of theory, sampling design, recruitment strategies, weighting techniques, analyses approaches and dissemination activities will be discussed. Application of such methods may lead to better identification of service deficiencies, leading to improved planning efforts by policy makers, stakeholders and institutions.
